Preliminary inquiry into the difference in sex ratio at birth in China]

Based on population statistics from China's 2nd and 3rd national censuses, China's unusually high male/female birth rates are examined. It appears that the lower male/female birth rates are generally found in China's minority-populated autonomous regions. Xizang Autonomous Region (Tibet) has the nation's lowest male/female birth ratio of 101.3; the highest ratio, 112.5, is in Anhui province; the national average for 1981 was 108.47. Although geographic, socioeconomic, and other factors may be attributed to regional differences, it is maintained that the high male/female birth rate is universal throughout China. The significant difference between the relatively high male/female birth rate in China's urban areas in 1981 (109.9), and the lower rate in the rural areas (107.6) is challenged by the author, who suggests that China's urban statistics are unquestionably more reliable than the rural statistics. The author suggests that factors such as the importance of raising male offspring, China's traditionally male-dominated family system, and the desire for male farm workers is strongest in China's rural sector. The current male/female birth rate is not a recent trend; prior to 1949, the male/female birth rate ranged from 110 to 115.     

The situation concerning marriage and births among childbearing women in Shaanxi province]

The results of a 1978 survey of 10 percent of the population of Shaanxi province, China, are presented. The survey contained questions on selected demographic characteristics of childbearing women. Data are included on marriage patterns, divorce, widowhood, fertility, and number of living children. Abbreviated life tables for both sexes for the province are also included.     

The new marriage law and planned birth]

The New Marriage Law was passed during the Fifth National People's Congress. It raised the minimum marriage age from 20 years for men and 18 years for women stipulated by the Old Marriage Law to 22 years for men and 20 years for women. It also differs from the Old Marriage Law in that it strengthens its encouragement of late marriage, late births and birth control, emphasizes that birth planning is the duty of both husband and wife, and prohibits marriage of collateral blood relations within 3 generations (the Old Marriage Law's standard was "to follow custom"). A third of the provisions of the New Marriage Law concern family planning, of which the first 3 clauses are the most important: 1) To set guidelines for the relationship between marriage and family: the New Marriage Law is concerned with not just the family, but also marriage and birth and expects all citizens to comply with and protect these standards. 2) To implement freedom in marriage--equality for men and women; to protect the rights of women, children, and the aged; to implement planned birth. 3) To prohibit any action that prevents freedom of marriage, such as marriage on a mercenary basis and to prohibit financial profit from marriages. Other clauses include: 1) direct blood relations and victims of leprosy or other diseases determined unmarriageable by the medical profession are prohibited from marriage; 2) after marriage registration and with the mutual agreement of both parties, either partner can become a member of the other's family; children can take either parent's surname; both partners have mutual rights of inheritance, as do parents and children. In Heilungjiang Province, data from September 1980 show that 87.5% of its fertile women used contraceptives. From January to September 1980 85.6% married late; the rate of applications for One Child Certificates was 80%. By 1979 the rate of natural population increase was 10.14/1000.     

Educational attainment and the transition to first marriage among Japanese women

I use data from a large nationally representative survey to examine the relationship between women's educational attainment and the timing of first marriage in Japan. The results indicate that later marriage for highly educated women primarily reflects longer enrollment in school, that university education is increasingly associated with later and less marriage, and that the trend toward later and less marriage is occurring at all levels of educational attainment. These findings are consistent, albeit weakly, with the argument that higher education should be negatively associated with marriage only in countries in which gender relations make it particularly difficult for women to balance work and family.     

Age of entry into marriage and the date of the initiation of voluntary birth control

It is widely known that modern economic development has been accompanied by the initiation and spread of effective limitation of fertility, and that generally the populations which experienced development at a late date also had a belated reduction in childbearing. Here a surprising relation is found between (and within) broad regions: the areas in which traditional age of entry into marriage was late were the areas in which marital fertility was reduced first.     

The continuation of education after marriage among women in the United States: 1970

Data from the 1970 National Fertility Study are used to assess the extent and determinants of post-nuptial education among women in the United States. Over one-fifth of all women have attended high school or college since marriage; over one-third either have returned to school or anticipate returning to an academic institution sometime in the future. This phenomenon is apparently increasing since women married less than five years have already attended school in as great a proportion as women married 15-19 years. Examination of differentials reveals for both blacks and whites that post-nupital education is higher among women who: (1) attended college before marriage, (2) married early, (3) are currently separated or divorced, (4) support egalitarian sex-role attitudes, or (5) whose most recent occupation is in the professional, managerial, or administrative category. Post-nuptial trends in education undoubtedly reflect the much broader social phenomenon of changing sex-role perceptions.     

Entering first union: the choice between cohabitation and marriage among women in Italy and Spain

While in Spain and Italy cohabitation has not acquired the same role that it has had in Northern Europe, in both of these Mediterranean countries cohabitation is no longer a marginal phenomenon. Moreover, the nature of cohabiting couples is diverse. According to the most recent FFS data, first cohabitations constitute a temporary arrangement that usually ends in the formalization of the union (marriage), and within 5 years 28.9 % of first cohabitations in Spain and 51.7 % in Italy were transformed into marriages. Within a Western context of changes in union formation patterns, the study of the choice between marriage and cohabitation as first union is of great significance. Is it possible to identify a shared pattern of union formation in Mediterranean countries like Italy and Spain? The purpose of this paper is to examine the choice between cohabitation and marriage as first union (timing, incidence and determinants) using a comparative life course approach. For the analysis of the timing and prevalence, cumulative incidence curves are calculated by birth cohorts and regions; while two semiparametric competing-risks models are estimated for the determinants of first partnership formation (one for each country), considering birth cohort, parental separation, educational attainment, employment status, age at leaving the parental home and birth of a child (the last three time-varying) as independent variables.     

The impact of economic resources on premarital childbearing and subsequent marriage among young American women

This paper extends previous work on premarital childbearing by modeling both the entry rates and the exit rates of unwed motherhood among young American women. In particular, I investigate the impact of economic resources on the likelihood of experiencing a premarital birth and then of subsequent marriage. Using a multiple-destination, multiple-spell hazard regression model and a microsimulation analysis, I analyze the accumulating effects of various economic variables. The results show that the economic resources are indeed important both for premarital childbearing and for subsequent marriage. However, the simulations show that large changes in these economic variables do not necessarily translate into large changes in nonmarital childbearing.     

Schooling,marriage, and age at first birth in Madagascar

The low school attainment, early marriage, and low age at first birth of females are major policy concerns in less developed countries. This study jointly estimated the determinants of educational attainment, marriage age, and age at first birth among females aged 12–25 in Madagascar, explicitly accounting for the endogeneities that arose from modelling these related outcomes simultaneously. An additional year of schooling results in a delay to marriage of 1.5?years and marrying 1?year later delays age at first birth by 0.5?years. Parents’ education and wealth also have important effects on schooling, marriage, and age at first birth, with a woman's first birth being delayed by 0.75?years if her mother had 4 additional years of schooling. Overall, our results provide rigorous evidence for the critical role of education—both individual women's own and that of their parents—in delaying the marriage and fertility of young women.     

A retrospective comparison of water birth and conventional vaginal birth among women deemed to be low risk in a secondary level hospital in Australia

BackgroundWater birth involves the complete birth of the baby under warm water. There is a lack of consensus regarding the safety of water birth.AimThis study aimed to describe the maternal and neonatal outcomes associated with water birth among labouring women deemed at low risk for obstetric complications and compare these outcomes against women of similar risk who had a standard land birth.MethodA retrospective audit and comparison of women giving birth in water with a matched cohort who birthed on land at Bankstown hospital over a 10 year period (2000–2009).ResultsIn total 438 childbearing women were selected for this study (N = 219 in each arm). Primigravida women represented 42% of the study population. There was no significant difference in mean duration of both first and second stages of labour or postpartum blood loss between the two birth groups. There were no episiotomies performed in the water birth arm which was significantly different to the comparison group (N = 33, p < 0.001). There were more babies in the water birth group with an Apgar score of 7 or less at 1 min (compared to land births). However, at 5 min there was no difference in Apgar scores between the groups. Three of eight special care nursery admissions in the water birth group were related to feeding difficulties.ConclusionThis is the largest study on water birth in an Australian setting. Despite the limitations of a retrospective audit the findings make a contribution to the growing body of knowledge on water birth.     

Entry into marriage and parenthood by young men and women: The influence of family background

We investigate the influence of family background on early entry into marriage and parenthood among white, Hispanic, and black men and women ages 14 to 22 in the first (1979) wave of the National Longitudinal Survey of Youth. Family background is highly associated with early entry into marriage for whites of both genders and female Hispanics and also with early entry into parenthood for all groups except black males. Large group differences in family characteristics explain most of the difference between white and Hispanic women in early marriage and parenthood and about half the difference in early parenthood between black and white women but do not explain the observed variations among other race-gender groups.     

A preliminary inquiry into the problem of floating population in Shanghai city proper]

Shanghai's geographic location and socio-economic status make it the most attractive city for transient population from all over China. As a result of the country's rapid economic development and policy of "openness and domestic economy vitalization, "Shanghai has increased its economic, scientific, and cultural communication with other Chinese cities and foreign countries. The transient population has also increased greatly. Between January and June, 1984, the transient population reached 136,880,000. A study conducted at midnight on August 10, 1984 surveyed the transient population, with the following results: 1) Based on random sampling of data collected by the 46 Household Registration Committees, temporary visitors in Shanghai's residences totaled between 315,286 and 359,602 persons 2) Hotel residents: 125,000 3) People residing on boats: 19,000 4) Temporary residents in 10 suburban areas: 20,000 5) Other transient population consists of temporary factory and construction workers and farm produce vendors: 79,000 the total transient population at midnight on August 10, 1984 was 586,000 persons. 41.6% were visiting friends and relatives or came for medical assistance. 45.9% came from other provinces, 38.8% from local farm villages, 14.3% from nearby towns, and .93% from Hong Kong, Macao, and Taiwan. The transient population has contributed to the development, productivity, and supply of commodities to Shanghai, and increased the city's communication with other provinces, but measures should be taken to properly manage it. To better manage this problem, the following steps must be taken: 1) Survey the population -- number, composition, distribution, sources, and activity patterns; 2) Classify by profession and centralize management; 3) Establish methods for proper distribution and diversification of market and entertaining areas; and 4) Improve roads, communication, and hotel facilities.     

Why marry? Race and the transition to marriage among cohabitors

Our study investigates the transition to first marriage among cohabiting black and white men and women, drawing on data from the National Survey of Families and Households. Our results underscore the importance of economic factors on the transition to marriage for both black and white cohabitors. We also find that for black cohabitors, but not for whites, socioeconomic disadvantage during childhood reduces the odds of marriage. The presence of children in cohabiting unions tends to increase the chances of marrying a cohabiting partner for both blacks and whites. Our results demonstrate the importance of including cohabitation in research on the marriage process.     

Pregnancy care and birth outcomes for women with moderate to super-extreme obesity

PurposeTo describe the health service utilisation and birth outcomes of pregnant women with moderate to super-extreme obesity.BackgroundMaternal obesity is increasingly recognised as a key risk factor for adverse outcomes for both women and their babies. Little is known about the service utilisation and perinatal outcomes of women with obesity beyond a body mass index of 40.MethodWomen with a self-reported pre-pregnancy BMI of 40 or more, who had received care and birthed a baby at the study site between 1 January 2009 and 31 December 2010. Clinical audit was used to identify the health service utilisation and birth outcomes of these women.Results153 women had a BMI of 40 or more. Women saw 6 different health professionals during pregnancy (1–16). Most of their visits were with a medical practitioner, often with limited experience, and almost all women only saw a midwife once at their booking visit (n = 150, 98.0%). While the majority of women experienced a normal pregnancy, free from any complications, almost half the women in this study experienced a caesarean section (n = 74, 48.4%).ConclusionClinical audit has been useful in providing additional information which suggests current maternity care provision is not meeting the needs of this group of women. The model of antenatal care provision may be a mediating factor in the birth outcomes experienced by obese women. The development of effective, targeted antenatal care, designed to meet the needs of these women is recommended.     

The temporal relationship of marriage,conception, and birth in Massachusetts

An investigation into the timing of first births in relationship to the date of marriage in Massachusetts confirmed the finding of previous national and local birth timing studies that first births likely to have been conceived before the marriage of their parents constitute a substantial proportion of all first births. The differential frequency of premaritally conceived births among various subgroups appeared to account for the variation noted in the overall timing patterns of first births after marriage. Data were gathered through linkage of certificates of birth of a sample of legitimate first children with the marriage record of their parents. Analysis of the marriage-first birth interval by maternal age and race, type of marriage ceremony, and occupation of the bride and groom were conducted and comparisons with previously published data were made. Separate consideration was given to the frequency and characteristics of those births likely to be premaritally conceived and those likely to have been conceived after the wedding.     

A preliminary inquiry into the interrelationship between population growth and economic development in Hong Kong]

Hong Kong includes Hong Kong Island, Kowloon, New Territory, and more than 230 islands. During World War ii, the population of Hong Kong decreased sharply, and the total number decreased to less than 600,000. Since the war ended in 1945, the population of Hong Kong has been increasing rapidly at an annual rate of 20%. By the end of 1981, its total population had increased to 5.2 million, including 1.25 million newly arrived immigrants. The average age is 24.8. People above the age 65 constitute only 6% of the total population. This shows that there is a sufficient supply of labor for local economic development. Because of continued economic growth, there has been a constant demand for more labor. Low wages provide an excellent condition for high-speed industrial development. An improved quality of professional workers and management personnel also contributes much to Hong Kong's industrial modernization. Because of high employment among the labor population, the general population earns income and spends a great deal, and this has created a rather active economy. General population growth trends include: 1) continued population growth will bring the total population to 6.3 million by the end of 1981, and the housing problem will become more serious; 2) a stable decline in the natural population growth rate will gradually change the population pattern to a low birth, low death, and low natural growth situation; and 3) improvements in science and technology, health care, and living conditions will reduce the death rate, and the average age will lengthen, and with the increase in old people, the demand for social welfare will also increase; and 4) there will be a shortage in experienced labor (professional technicians and high management personnel) in the 1980s. Facing the new situation, Hong Kong's economic structure needs reform, moving from a labor intensive enterprise to a capital-technological intensive enterprise. The market will be expanded and Hong Kong will earn more profit in China's mode rnization process.
