Since 1949 and in particular the 1970s, China's fertility rate has undergone rapid and continuous change. This is a direct reflection of China's success in population control. The decline in China's fertility rate regulated the speed of population growth, altered the population structure, and brought population development to be in line with economic development. Data used in this article are from the National 1/1000 Random Sample of Fertility (1982), the 10% Sample of the 1982 Population Census, 1981, 1983 and 1984 statistical yearbooks, and other data from the Statistics Bureau. China's fertility rate dropped an annual average of 2.5/1000 from 1950-81. However, this time, the fertility rate fluctuated, depending on political, social and economic factors. As the nation prospered, the fertility rate remained stable and high; as China suffered severe economic losses, the fertility rate dropped. A steady decline was evident beginning in 1970 as the government began to propagandize the merits of smaller families. Between 1971-83 the average yearly rate of growth was 1.6%. The number of years a woman was fertile was similar for both urban and rural women in 1964 and 1981; moreover, in 1981 both groups showed a sharp drop in fertility between the ages of 27-35. The 1 child rate for urban women rose from 21.9% in 1964 to 86.6% in 1981. Urban women tend to be more receptive to late marriage, late births, and fewer children. This change in the 1 child rate contributed to the drop in the birth rate of 31.1/1000 in 1964 to 20.9/1000 in 1981.  相似文献

In 1982, the Chinese State Family Planning Commission conducted a nationwide fertility survey of 1 person/1000 in 28 provinces, municipalities, and autonomous regions. 815 sample units were selected and 310,462 women aged 15-67 were interviewed, 99.9% of those identified. 252,094 (24.77%) were of childbearing age (15-49) with 24.76% 15-19 years old. Among women of fertile age, 31.46% were unmarried, 64.53% were married to their 1st husbands, 2.89% were remarried, .19% were divorced, and .94% were widowed. Average age of 1st marriage increased from 18.4 in the 1940s to 22.8 in 1981. Total fertility rate dropped from 5.44 in the 1940s to 2.63 in 1981. In 1981, the birth rate was 85/1000 women of fertile age. Fertility was much higher among minority nationalities. 118 million of China's 170 million married couples of reproductive age (69.46%) use birth control at present; 50.2% use the IUD, 25.4% tubal ligation, 10.0% vasectomy, 8.2% oral contraceptives, and 2.0% condoms. About 21 million married women should have begun using contraception but have not. 14 million or 42.3% of 33 million 1 child couples have pledged to have only 1 child. If the fertility level of 1981 is maintained and the average woman continues to have 2.63 children, 2.91 in rural areas, China's population will reach 1.2 billion by 1993 and will exceed 1.3 billion by 2000. The Central Committee has a target population of 1.2 billion by 2000.  相似文献

China's fertility rate, affected by various economic, cultural and social factors, is in a state of flux. In analyzing the major factors affecting the change, and in determining a fixed ratio for the degree of effectiveness of each factor, it is possible to improve birth policy in terms of predicting trends in fertility changes. Based on data gathered in 1981, the following observations were made: 1) A look at gross output value for industry and agriculture by geography shows that the more economically developed an area is, the lower is the fertility rate, and that the less economically developed an area is, the higher is the fertility rate. For example, Yunnan, with an average gross output value per person of 406.5 yuan, has a total fertility rate of 3.814, whereas Shanghai's average gross output value per person is 5566.4 yuan, and its total fertility rate is 1.316. 2) Figures comparing educational levels with total fertility rates show that cities with a greater number of women with a middle school education tend to have a lower fertility rate than cities with fewer such women. For example, Beijing's 516,000 middle school educated women have a total fertility rate of 1.589, compared to Anhui's 186,000 middle school educated women who have a total fertility rate of 2.799. Also, among college educated women, the fertility rate is 41.5/1000, the 1 child rate is 88.6%, and the multiple child rate is 1.2%, whereas those women with a primary school education have a fertility rate of 86.4/1000, a 1 child rate of 44.3%, and a multiple child rate of 26.7%. 3) As towns become urbanized, the fertility rate of those towns tend to decline. For example, Sichuan, with an Urbanization Index of 14.3 has total fertility rate of 2.650; Tianjin's Urbanization Index is 68.7, and its total fertility rate is 1.645. 4) A comparison of women engaged in physical labor to those in non-physical jobs shows that the former tend to have a higher fertility rate: women working at physical labor have a fertility rate of 86.7/1000, compared to a fertility rate of 65/1000 for those in non-physical jobs. 5) China's family planning programs advocating late marriage, late births and 1 child per couple in itself does not influence fertility rates, but taken with economic factors, it will have far reaching consequences. For example, cities with high gross output value tend to have a higher rate of 1 child per couple. 6) As the average age at marriage for women rose from 18 years in 1949 to 23 years in 1981, the rate of women having multiple children has declined in all age groups since 1964.  相似文献

In 1981 a 3% random sampling of women born between 1931-66 was taken in Shanghai to study their menstrual and marital histories, pregnancies, contraceptive use, education, and occupation. In the last 30 years the fertility rate and the rate of natural population increase began to decline beginning around 1957-58. The changes in fertility rate fall into 3 periods: 1) between 1958-61 the fertility rate fell from 238.6/1000 to 159.2/1000, averaging 26.5/1000 annually; there was a slight period of stability from 1961-63; 2) between 1963-67 it fell from 155.8/1000 to 56.3/000, averaging 24.9/1000 annually and between 1967-68 there was a slight increase; and 3) between 1968-74 it fell from 63.2/100 to 26.4/1000, averaging 6.1/1000 annually. The fertility rate of various age groups also declined during the last 30 years. The average number of children for married women was 1.92. Factors influencing the fertility rate include: 1) birth control policy: the changes in the fertility rates were dominated by the birth control policy; for instance, from 1956-60, after late marriages were officially advocated, the average age at 1st marriage for men was 1.64 years older than before; between 1962-64, those women with more than 3 children were sterilized. 2) Education: the higher the educational attainment, the later was the age at 1st marriage, the more effective was the use of contraceptives and the lower the standard was for fertility; 3) occupation: the type of job influenced the age at marriage, as well as the frequency of miscarriage and live births; 4) attitude towards children: the total number of children women reported they would like averaged out to be 1.7; 5) urban and rural differences: the fertility rate for Shanghai City was not only lower than for Shanghai County, it fell at a faster rate; 6) changes in the age structure of fertile women affected the fertility rate; and 7) others: nutrition, the ability to propagate, age at 1st marriage, plus economic and social factors all affected fertility.  相似文献

Immigration is an important factor in America's population growth. In the last 200 years over 50 million persons immigrated to the U.S.; 99.6% of the current total population are descendents of those immigrants. In the 1930s, American population decreased by about 7.2/1000, but during the 1950s the annual rate of natural increase rose to 18.5/1000. In the 1960s, this rate began to decrease until the 1970s when it was about 9/1000. By 1981 and 1982, the rate of natural increase declined to 7/1000. These changes are due to the relatively slow decline in the mortality rate of the last 30 years (10.6/1000 in 1945 to 9/1000 in 1981) and to the fluctuations in birth rates (from 19.5/1000 in 1945 to a high of 25.3/1000 in 1957 and back to 16/1000 in 1981). Birth rates are influenced by factors such as the number of fertile women, age structure, fecundity, marriage, family, occupation, and education. In 1950 there were 38,920,000 women aged 15-49, and by 1980 there were 57,630,000. Of these, in 1950, 31.28% were aged 20-29, the most fertile period for women, as compared with 35.04% in 1980. Thus, in postwar America, the changes in birth rate did not follow changes in the number of fertile women. Marriage patterns also underwent changes, particularly in the last 20 years. From 1930 to 1935, the marriage rate was 8.6/1000. By 1945, it rose to 16.4/1000. But during the 1960s, an increasing number of women aged 20-29 years remained unmarried. At the end of the 1970s, there was also an increase in the number of married women who did not have children. Furthermore, the number of divorces increased, an additional reason for a declining birth rate. Changes in family structure also influenced postwar American reproduction. In the last two decades, the traditional family has almost disappeared and the nuclear fammily is on the decline. By 1970 there were more people living alone, single parent families, and unrelated people sharing a domicile, than there were family units. Also, educated women who worked often married at a later age, thus placing restrictions on the birth rate.  相似文献

At the end of 1981 Yanging County had 26 communes, 375 production brigades and a total population of 211,098. A random sampling of 5.07% of the production brigades was taken, which included teams from the plains as well as mountainous regions. The sample had a population of 10,888, or 5.16% of the entire county, among whom 189 subjects were interviewed. These 189 women, whose ages ranged from 35-67, were divided into 5 birth year cohorts (1914, 1920, 1930, 1940, 1946). Findings include: 1) Age at marriage: the average age at marriage (about 17 years) between the 1914 and 1946 groups rose 1.82 years, indicating that early marriage was the norm. The time between marriage and 1st birth has shortened. 2) Fertility data: from 1914 to 1946 the lifetime fertility rate tended to decline from 4.60 to 3.70, but the 1930 cohort was the highest (6.42), followed by the 1920 cohort (6.26). The fertility rate of the 1914 cohort tended to rise in the 1950s after already having reached a peak in the early 1940s, probably because after Liberation fertility rose due to a higher standard of living and a stablized society. The fertility of the 1930 cohort was highest around 1963 when they were already 30 years old. The fertility of the 1940 cohort was also highest beginning around 1963. In both cases, the reason probably was because the national economy improved at this time. Indeed, the national fertility rate rose from a 1960 low of 20.9/1000 to 43.6/1000 in 1963. 3) Contraceptive use: prior to 1972 before there was an offical birth control policy, a sizeable number of women already desired to use contraceptives, the reason being most of these women felt they already had enough children. However, many women did use contraceptives in response to the call to do so. 4) Factors influencing fertility standards: in general, the less a woman's education and the lower her income, the higher was her standard of fertility, and vice versa. 5) The percentage of women who had children who died before the age of 15 ranged from 35.9% of the 67 year olds to 12.6% of the 35 year olds.  相似文献

The dynamic characteristics of China's 5 distinct stages of population development since the People's Republic of China was established in 1949, namely, 1950-1958, 1959-1963, 1964-1970, 1971-1981, and 1982-present, are outlined and discussed. By tracing both the overall rate of population growth and age-specific fertility rates for women aged 15-45 (5-year groups), a clear pattern emerges which indicates that the rates of early and late fertility (ages groups 15-19 and 30-45) are significantly declining. This is interpreted as a key factor in the overall decline in fertility rate. Annual statistics showing the number of children per woman of childbearing age and interval between 1st marriage and 1st birth are compared and discussed. It is concluded that the overall decline in birth rate and fertility rate since the 1970's is attributable to China's successful family planning campaign.  相似文献

The population of Henan Province is 72,850,000, 92% of whom live in villages. From July 12 to August 11, 1981, a fertility survey was taken of 20 communes and 31 work brigades in the counties of Fugou, Shancai, and Dengfeng, in which 38,168 people and 5700 fertility registration forms were studied. In 1980, 15% of the 3 counties' population were women aged 18-49, 80% of whom were married. The birth rate was 134.56/1000, of which the rate for married women was 172.36/1000. A random sampling from Shancai of 18-49 year old women showed an average of 2.3 children per couple. The factors influencing rural fertility are economic, social, ideological, and cultural. The economic system of distribution according to work has actually encouraged population growth because in rural areas where the standard of living is low larger families with more workers have greater incomes than smaller families with fewer workers. Early marriage and early births are encouraged under this system, as evidenced by findings in Fugou County. The survey also found that in the 3 counties, virtually everyone marries, women who work tend to work in the village close to home, high illiteracy is prevalent, and traditional attitudes of favoring males over females were all factors contributing to early and frequent births. In order to lower rural birth rates, rural economy should be developed, old attitudes and habits should be changed, and literacy should be increased.  相似文献

The 1982 census provided detailed information on fertility in China. It recorded 20,689,704 births in 1981, producing a birth rate of 2.1%, a decrease, respectively, of 43% and more than 50% in comparison with 1952 and 1963. The birth rate has varied widely over the last 30 years, from 3.6% in the early 1950's, to 1.8% in 1961, after a planned birth program was begun, to a record high of 3.7% in 1962 following the economic recovery, to 3.3% in 1970, after a gradual decline through the 1960's. By 1981 the birth rate had declined to 2.1%, clearly resulting from the intense planned fertility promotion begun in the early 1970's. In the mid- and late 50's, urban birth rate was consistently higher than rural, with the mass move to the cities at the beginning of the People's Republic. General economic development after 1957 brought simultaneous declines of both urban and rural rates, both reaching a low point in 1961. Age structure of the population also has an influence, depending on the proportion of childbearing women in the population. In 1981, the fertility of China's childbearing women was 8.3%, lower than that of the developing countries, but higher than the developed countries. By age group, the fertility rates reached 14.7% and 23.9% respectively in women between 20-24 and 25-29 years of age; the legal marriage age is 20. The fertility rate in large cities is generally lower than that of provinces. Higher educational and socio-economic level also exert an inverse influence on fertility rates; in low socio-economic areas the rate reached 3.5%, and in more advanced areas it was held to 2.2%. In all professions with the exception of agriculture, fishing, and forestry, the percentage of families with 1 child was 81.8%. Since planned fertility was implemented, the overall fertility rate has dropped from 3% to 2%. China's fertility mode has changed to that of developed countries, with high intensity between 20 and 29 years of age. Appropriate measures should be taken to lower the fertility rate in different regions.  相似文献

生育意愿研究有水平研究和趋势研究两个视角,后者更能反映人们观念的变迁,更能预判未来生育水平的变动。文章以上海市为例,采用横断历史元分析法(Cross-temporal meta-analysis),将1981年以来的30多年间上海市范围内开展的26项涉及居民生育意愿调查的结果串联起来,结合其中5项调查的个案数据分析,考察我国大城市不同社会经济特征人群的生育意愿纵向变化趋势并进行子人群间的比较。研究发现20世纪80年代以来上海户籍城乡居民的生育意愿均不断减弱并且二者逐渐趋同,生育意愿的"城乡之别"已然消失;在沪外省市流动人口的生育意愿强于户籍人口,"内外之分"仍然存在,但也显示出未来有趋同的可能性;独生子女与非独生子女的生育意愿比较显示户籍人口中独生子女与非独生子女的生育意愿差异极小,流动人口中非独生子女的生育意愿略强于独生子女;从不同文化程度和收入水平的人群比较来看,文化程度越高的户籍人口生育意愿越强,流动人口的生育意愿随文化程度的提高呈现"两头高、中间低"的特征,无论是户籍人口还是流动人口,高收入人群的生育意愿均相对较高;但是无论哪个人群的平均意愿子女数均已低于2个孩子。  相似文献

This report attempts to analyze the negative population growth and its significance in Tai-Cang County, China. Based on population data provided by local Tai-Cang authorities, family planning effectively lowered the birth rate from 11.9% between 1960-1969 to 3.0% between 1979-1983. The rate of single-child families grew enormously while the number of 2-child families reached a record low. Families with more than 2 children virtually vanished by 1983. Moreover, while a younger marriage age in 1981 and 1982 contributed to a slight increase in the birth rate, new marriage laws in 1983 caused an older marriage age and acted to lower the birth rate due to the fact that mothers were bearing children at an older age. A change in population components also influenced this low birth rate: the county population below the age of 14 is 21.2% compared with 33.6% nationally; however, the percentage of the population in this county over the age of 65 is 8.5% while the national figure is 4.9%. Finally, the marriagable population of females (i.e., 23 years old) was slightly lower between 1982-1984 due to the low birth rate seen from 1959-1961. The findings indicate that family planning is effective in lowering birth rates along with late marriages and older childbearing ages. The negative population growth in Tai-Cang County, however, is a temporary phenomenon. The indications are that the problems and shortcomings of family planning must be overcome, regional population planning must be improved, and the study of eugenics and optimum population reinforced. The report also notes that the population trend is toward aging.  相似文献

Due to imperfections in the current family planning (FP) policy, and the differences un program implementation in urban and rural areas, the fertility of the urban population with higher IQ scores is under control but this is not the case for the rural population. Among rural couples, one child is rare and two or three are commonplace, while in cities over 70% of couples are having one child. In the metropolitan cities, this figure is about 90%. In the rural areas, provision of education is a serious problem because of insufficient resources, a lack of qualified teachers and inadequate facilities. At the present, at least 3 million school age children in rural areas can not go to primary school. Besides there is a big contrast in FP practice between Han nationality and minorities. Population growth is basically under control among the more advanced Han nationally but not among the less advances minority nationalities. This growth rate among the minority population was about 50.27/1000 in the past five years, which is alarming. Furthermore, the couples given opportunity to have a second child are often those whose first child had birth defects or is mentally retarded, whereas couples with a normal child can have only one child. This has become a vicious circle, since subsequent children are more likely to have the same birth defects. It was discovered from a 1983-85 survey that the prevalence of birth defects was 12.8/1000. The current situation is that the fertility of urban, educated, and healthy people is restricted while the less educated, those living in less developed areas, and those with health defects are having more children. The outcome of this situation is the decline of national population quality, which greatly deviates from the original intention of the FP.  相似文献

The Uighur Autonomous region in Xinjiang includes a number of minority groups such as the Uighur, Kazakh and Hui. The question of how to implement family planning in minority areas if of utmost importance. In February 1982, the State Council decreed that family planning policy for minority groups could justifiably be more lax than for the Han people, who comprise a majority of Chinese population. Instead of advocating 1 child per couple, as is the current national policy, urban minority groups are permitted 2 (with exceptions, 3) children per couple and rural villagers are permitted 3 (with exceptions, 4) children. The 1982 National Census showed that the natural rate of growth for Xinjiang was 13.63/1000 (compared to the national rate of 11.45/1000) with individual minority growth rates as high as 20.11/1000. The area's gross output value cannot keep up with this population increase. Over half of Xinjiang's minorities are of the Islamic faith, which teaches that births are not self-willed. It is crucial to inculcate in them that births can indeed be planned. Also, their custom of early marriage (age 15 for girls and 16 for boys) which leads to a high fertility rate, must be changed. Although Xinjiang's land mass is great, only 38.4% is arable, so the common belief that its population can grow without limit is fallacious. When family planning was being implemented nationwide, for minorities it was only propagandistic. After the population growth for the majority Han was under control, the minority groups declared family planning programs would also benefit them. Symposiums were held contraceptive use became voluntary among many women. The birth rate fell from 22.5/1000 in 1981 to 14.09/1000 in 1985. Family planning also received approval from religious leaders. But because population distribution and growth are uneven in Xinjiang, family planning policy must reflect these differences.  相似文献

In July, 1981, the staff of the Population Research Section of the Economics Department of Wuhan University and family planning personnel at the local level conducted a survey on fertility in the rural areas of Hubei Province. The survey was conducted in the forms of public opinion polls and individual conversations with the local people. The results of this survey can be summarized as follows: (1) Marriage Question -- the average age for first marriage is 22.54. The marriage rate is 5.3/1,000 for age 18, 35.5/1,000 for age 19, 54.2/1,000 for age 20, 171.9/1,000 for age 21, 393.5/1,000 for age 22, 717.8/1,000 for age 23, 886.3/1,000 for age 24, and 965.3/1,000 for age 25. (2) Birth Question -- average time between first marriage and first child is two years. Women between the ages of 25 and 29 average 2 children; women between the ages 20 and 24 average 1.3 children. Figures show that an unlimited population growth is already under restraint, and the fertility rate shows some obvious decline. (3) Ideological Question -- traditional beliefs favoring more children and favoring boys to girls are still strong in the minds of the people. In general, young males and females still contemplate an early marriage and wish to have two children. In order to correct the people's ideology and match it with national population policy, more work is needed in family planning.  相似文献

In 1982 the Chinese National Family Planning Commission conducted a nationwide (excepting Taiwan and Tibet) .001 random sampling of the total population to gather data on the fertility and age structures of married women. In comparing general marital fertility and standardized fertility, findings show that from 1964 to 1970 both rates averaged 225.1/1000. When family planning work began on a wide scale in 1971, the rates steadily declined, reaching 116.7/1000 in 1980. However, in 1967-68 the standard fertility rate rose by 21.34% due to the chaos of the Cultural Revolution, and in 1980-81 the rate increased by 13.2%, indicating that problems still remain in family planning. The total marital fertility rate dropped 2.84/1000 from 1964 to 1981. The rate of decline in rural areas was greater than in the cities, but the cities had a larger percentage decline than the countryside. In the 5-year periods of 1965, 1970, 1975, and 1980, marital fertility rates tended to decline in 1970 and 1975 among women aged 30-40 years because during those periods greater control was placed on women having multiple children. For 1980 and 1975, combined total rates for 15-19 year olds dropped 17.1%, but the combined total rates of 30-49 year olds dropped by 61.2%, indicating that in recent years the drop in marital fertility is mostly among those over 30 years of age.  相似文献

The birth rates of the USSR within its present boundaries are reconstructed for the period 1918-1940 on the basis of incomplete data and taking into consideration several changes in frontiers. Estimates for the years 1941-1945 are derived from data on school attendance during the 1949-1954 period, as well as from data provided by the censuses of 1959 and 1970 concerning cohort survival. Deriving an "effective fertility rate," which adjusts for the mortality wastage of young children, discussion focus is on fertility trends until 1976 and the changes in age patterns of reproduction at the national level and in the various republics. During the 1918-1940 period, the birth rate in the USSR never fell below 30/1000 and never exceeded 45/1000. There was a significant drop in the birth rate in the 1931-1936 period, and this is attributable to the problems of the period of collectivization and to the large-scale processes of migration involved in the country's industrialization. After the late 1940s, the overall birth rate in the USSR stabilized at a level of 25-27/1000, but from 1960 onwards, there was a steady decline in the rate. The level reached its lowest in 1969 and then rose somewhat. This increase reflects the transient influence of changes in the age-marriage structure of the population and in the "timetable" of births. A comparison of the present fertility level with the level in the 1920s indicates that the birth rate has declined by a factor of approximately 2.5, but in evaluating this decline the sharp decline in mortality, particularly infant mortality, must also be considered. The child mortality level in prerevolutionary Russia was very high. The overall mortality rate for the 20 provinces of European Russia in 1920-1922 was 33.2/1000, namely, 1/4 higher than it was before the Revolution. In subsequent years infant mortality continued at a high level and was 18.2% in 1940. In the last 25 years mortality in children under age 5 has markedly declined. In 1976 the overall birth rate was 18.5/1000 and the "effective" birth rate was 18.0/1000. The practice of birth control in families is spreading in various ways. In some cases the proportion of married couples using family planning is increasing, while in other cases couples already using birth control are beginning to use it after the birth of a child lower in birth order. In most areas of the country birth control is being practiced predominantly in such a way as to keep families down to 1 or 2 children. For the whole of the USSR in 1973-1974, the gross reproduction rate was 1.178, while the net rate was 1.118. Although there is ample population replacement in the country as a whole, in a number of republics even mere replacement is threatened.  相似文献

The National Committee on Family Planning conducted a sample survey of fertility in the Yi-yang area in September 1982. The survey was focused on the marriage and fertility status of women between the ages of 15 and 67. Results from this survey show that early marriage is still very popular. Only 40% of those surveyed delayed their marriage to a later age. There is a need to educate the people on the benefits of late marriage. In addition, statistics show that the average fertility rate for a woman was 6.8 children in 1970 and 2.35 children in 1982. This recent figure is still too high when compared with the under 1.2 figure suggested by the central government. Among the total number surveyed, only 77% have taken birth control measures, and the other 23% still have not taken any birth control measures. The phenomenon shows that popular education on late marriage and having children at a later age is still urgently needed in order to further reduce the fertility rate. Married couples of childbearing age should be taught effective birth control measures and knowledge of eugenics with better education for the next generation. In this way, the masses may participate actively and positively in the national family planning campaign.  相似文献

Most developing countries are in the demographic stage of early mortality, high birth rates and high rates of natural population increase. A characteristic of developing countries is that after World War ii, particularly since the 1960s fertility rates are on the decline, even though they still remain high. The fertility rate of developed countries fell from a 1950 rate of 22.9/1000 to 15/1000 in 1982, a decrease of 34.5%, whereas the fertility rate of developing countries hovered around 43/1000 between 1930-1950, 40.6/1000 during the 1960s and 33/1000 in 1982. Between 1950 and 1982 there was a decrease of 24.8%. But the main reason for this decrease is the decline in the last 20 years of the fertility rates of China and India, whose rates fell 34.9% from 1960-1980. Changes in fertility rates are influenced by the age structure of a country, as seen in the changing age structure of developing countries from 1960-80. For example, an increase in fertility rates was 1 consequence of an increase in the number of fertile women aged 15-45 from 42.6% in 1960 to 44.4% in 1980. Nevertheless, there exists some sort of birth control, whether conscious or subconscious, because the number of births per fertile woman is 3-4 fewer than the 14-15 children a woman can theoretically bear. The reason for changes in fertility rates in developing countries can be traced to marriage and family customs, and even more important, to social and economic factors. For example, Asian, African and Latin American cultures tend to support early marriages. When the fertility rates of developed and developing countries are looked at for a comparable period, then the rate of decrease for developing countries is slower than developed countries. But, if the comparison is made for a transitional period (i.e., industrialization), then the rate of decrease for developing countries is faster than for developed countries. Currently there are 25 developing countries that have attained a fertility rate of 25/1000 or lower, and 52 developing countries with a rate of 35/1000.  相似文献

Abstract The paper describes a computerized model developed to simulate the fertility of a hypothetical marriage cohort in a closed population. The model was applied to England and Wales fertility data of marriage cohorts of the years 1951 to 1970. For each of these cohorts, the computer was programmed to construct five series of tables showing birth-order probabilities, family size frequency distribution, mean length of intervals between marriage and successive births, parity progression ratios and mean family sizes of fertile women. The results showed that the fertility of the cohorts of women who married between the middle 1950s and the early 1960s was character ized by a declining trend in the frequency of childlessness and by a dramatic increase in the proportion of marriages with two or more children. Since 1964 or so, there has been a downward trend in duration-specific birth-order probabilities. The analysis suggests that the recent drop in fertility may well prove to be the effect of an upward shift in the timing of births as well as a fall in completed fertility.  相似文献

Attention in this discussion of the population of India is directed to the following: international comparisons, population pressures, trends in population growth (interstate variations), sex ratio and literacy, urban-rural distribution, migration (interstate migration, international migration), fertility and mortality levels, fertility trends (birth rate decline, interstate fertility differentials, rural-urban fertility decline, fertility differentials by education and religion, marriage and fertility), mortality trends (mortality differentials, health care services), population pressures on socioeconomic development (per capita income and poverty, unemployment and employment, increasing foodgrain production, school enrollment shortfalls), the family planning program, implementing population policy statements, what actions would be effective, and goals and prospects for the future. India's population, a total of 684 million persons as of March 1, 1981, is 2nd only to the population of China. The 1981 population was up by 136 million persons, or 24.75%, over the 548 million enumerated in the 1971 census. For 1978, India's birth and death rates were estimated at 33.3 and 14.2/1000 population, down from about 41.1 and 18.9 during the mid-1960s. India's current 5-year plan has set a goal of a birth rate of 30/1000 population by 1985 and "replacement-level" fertility--about 2.3 births per woman--by 1996. The acceleration in India's population growth has come mainly in the past 3 decades and is due primarily to a decline in mortality that has markedly outstripped the fertility decline. The Janata Party which assumed government leadership in March 1977 did not dismantle the family planning program, but emphasis was shifted to promote family planning "without any compulsion, coercion or pressures of any sort." The policy statement stressed that efforts were to be directed towards those currently underserved, mainly in rural areas. Hard targets were rejected. Over the 1978-1981 period the family planning program slowly recovered. By March 1981, 33.4 million sterilizations had been performed since 1956 when statistics were 1st compiled. Another 3 million couples were estimated to be using IUDs and conventional contraceptives.  相似文献
