Age structure and economic policy: The case of saving and growth

The age structure of the population affects aggregate saving, which affects growth through investment. Growth in turn is influenced by other age structure effects and feeds back into aggregate saving by well known life cycle mechanisms. Some of these feedbacks are generally ignored in empirical work. Especially the age structure effect on macroeconomic variables is a commonly overlooked, yet easily accessible factor useful for prediction, policy evaluation and design. The connection between age structure, savings and growth in the OECD from 1950 to 1990 illustrates how policy analysis that ignores the macroeconomic effects and feedbacks from age structure changes is liable to lead to faulty and potentially costly conclusions about policy issues.     

Birth control and the black American: A matter of genocide?

Demography - During the 1960’s and continuing into the 1970’s, the charge that birth control and abortion are integral elements of a white genocidal conspiracy directed against...     

Birth limitation, late marriage and decline in the natural increase rate of the population]

Birth limitation and late marriage are two major factors which contribute to the reduction of population growth rate. These two factors should be used as the fundamental method for effectively controlling China's population growth. Facts have proved that birth limitation and late marriage are complimentary to each other and should match each other closely. Since late marriage cannot be delayed indefinitely, the average fertility rate for females under the age of 25 in their first marriage may still reach 5-6 children, provided that birth control measures are not taken. Because of this situation, at the same time that late marriage is encouraged, birth control should also be promoted positively. All married couples should be advised to have only one child. In order to ensure the everlasting practice of these two methods, certain policies concerning family planning and birth control should be formulated according to China's current economic situation. These policies include enforcement of an ideological education and social insurance practice in order to solve the problem of the high population growth rate in the countryside and effectively reach the goal of controlling China's population growth.     

Birth control socialization: How to avoid discussing the subject

Observational data from parents-adolescent son or daughter triads' discussions concerning birth control reveal the strategies used by both generations to avoid the transmission of information. Questionnaire data from all members of the triads provide additional confirming evidence that neither parents nor adolescents engage easily in birth control socialization.     

Birth control and regional differentials in the Soviet Union

Abstract Following the territorial division pointed out by Urlanis into those parts of the Soviet Union where birth control is practised and where it is not as widespread, it is possible to ascertain the importance of different factors bearing on fertility within each region. This study was based on data obtained from the 1959 USSR Census of Population including information on social and demographic characteristics of the urban and rural populations for over 150 political-administrative areas. In Central Asia, Azerbaidjan and Armenia, outside the region of birth control, the level of fertility depends mainly on the proportion of women who are married and also on their social position measured by the discrepancy in the educational status of men and women. In contrast, the birth control region of a relatively low level of fertility in urban areas, for example, displays the characteristic of women's educational achievement most strongly associated with the child-woman ratio. Except for the rural areas in this region, the present study fails to support the popular hypothesis that economic dependency of women is directly related to fertility.     

生育文明与我国未来生育率控制

我国的生育率变化一直以来都与生育文明的发展有着密切的关系。深厚的传统生育文化支持着我国农业社会的高生育水平,这在历史上起到过一定的积极作用,但是庞大的人口数量越来越成为我国经济社会发展的包袱。我国现阶段生育率已经在计划生育政策的控制下,达到了一个较低的标准。但是,这种低生育水平还很不稳定,也不可避免的带来了一些社会问题。随着我国经济发展和社会转型,推进生育文明的发展将成为稳定低生育水平,实现适度人口规模的最好方法。     

The spatial dynamics of stratification: Metropolitan context, population redistribution, and black and Hispanic homeownership

Racial and ethnic inequality in homeownership remains stubbornly wide, even net of differences across groups in household-level sociodemographic characteristics. This article investigates the role of contextual forces in structuring disparate access to homeownership among minorities. Specifically, I combine household- and metropolitan-level census data to assess the impact of metropolitan housing stock, minority composition, and residential segregation on black and Hispanic housing tenure. The measure of minority composition combines both the size and rate of growth of the coethnic population to assess the impact on homeownership inequality of recent trends in population redistribution, particularly the increase in black migration to the South and dramatic dispersal of Hispanics outside traditional areas of settlement. Results indicate remarkable similarity between blacks and Hispanics with respect to the spatial and contextual influences on homeownership. For both groups, homeownership is higher and inequality with whites is smaller in metropolitan areas with an established coethnic base and in areas in which their group is less residentially segregated. Implications of recent trends in population redistribution for the future of minority homeownership are discussed.     

The interaction of migration,income, and employment in Sweden

A common approach in migration studies is to explain interregional migration by single-equation models. Such models are likely to suffer from simultaneous-equation bias when used in studies attempting to analyze migration over a long period of time. In this study, a simultaneous-equation approach is applied, which takes account of the interdependence between migration and income and employment changes. The four-equation model is estimated for 70 labor market areas in Sweden.     

Birth rate trends and changes in marital fertility in the Netherlands after 1937

The rise in fertility in the Netherlands since 1937 is examined in the light of new statistical information which has recently become available. The conclusion reached is that a continuance of the high fertility rates of the recent past is unlikely.     

The effects of income level,income distribution,education and urbanization on fertility rates among 28 administrative regions of China

Conflicting empirical evidence on the role of income distribution on fertility rates is the impetus for this 1982 study of providence-specific Chinese Census data, excluding Tibet. The findings support the prior thesis of Repetto but utilize the micromethods and per household income measures of the competing findings of Boulier. It is cautioned that in the Chinese analysis equal income distribution depresses fertility, but China may not reflect world wide patterns. China did not have until recently a market incentive system, and there are income measurement problems. The data are per capita economic output not per capita income, and those high output areas which did not produce low fertility may actually have had households with low incomes. The importance of this research is in establishing that cross-province data are a useful tool in understanding the influence of income distribution on fertility. As with most developing countries, women's education, for instance, at least junior high education explained the largest variation of fertility differences among the 28 provinces. The urbanization variable when controlling for income was positive, unlike the other developing countries. The 1949 Chinese government's spatial industrial policy encouraged urbanization and industrialization in rural areas and family planning programs such that highly urbanized provinces have low population density. A variety of variables on income level, income distribution, education, and urbanization are discussed. OLSQ regressions were generated utilizing such independent variables as output per capita in yuan (YOUTHPC80), the square of YOUTHPC80 (YOUTHPC802), YOUTHPC80 multiplied by the average family size in each province (YOUTHPH80), and the squared value of YOUTHPH80.     

怀孕年龄与胎次对出生缺陷的影响分析

本研究通过抽取浙江大学医学院附属妇产科医院某病区5782个病例(736例患病),从出生缺陷的角度,通过对妇女怀孕年龄及胎次与胎儿畸形患病率的关系对开放二胎政策之后的人口质量的影响进行分析,发现孕妇年龄过低(19岁以下)与过高(35岁以上)均会导致出生缺陷率提高;而胎次的影响比较复杂,对于24岁以下的年龄段来说,胎次越高,患病率越高,而对于25-44岁的孕妇来说,除了第4胎及以上的患病率较高,第2、3胎的患病率没有明显的差别。因此,放开二胎将不会对人口质量产生显著影响。     

Education and survival: Birth cohort,period, and age effects

Previous studies have found that educational differences in mortality are weaker among the elderly. In this study I examine whether either cohort or period effects may have influenced the interpretation of age effects. Six 10-year birth cohorts are followed over 30 years through decennial censuses. Differential survival is inferred from changes in the relative proportions of a cohort in each education category as the cohort ages. In cross-section, younger persons generally show stronger education effects on survival, although this pattern is clearer for women than for men. There is evidence of period effects. Within cohorts, relative survival tends to increase with age.     

The Resource-Infrastructure-Environment Index for Measuring Progress: An Application to Australia, Mexico and the US

The resource-infrastructure-environment (RIE) index was proposed as an alternative measure of progress which was then employed to: (1) compare the aggregate (single summary) index findings between Australia (mid-industrialised nation), Mexico (emerging economy), and the US (highly industrialised nation); and (2) compare the RIE index against the gross domestic product (GDP), human development index (HDI) and genuine savings (GS) measure. This paper builds on the previous work by assessing the seven themes and 21 dimensions which comprise the RIE index for the three aforementioned nations, as well as the associated policy implications. The results identified Australia’s strength in the human resource and infrastructure themes. For Mexico, strong contributions came from the natural and generated resource themes as well as the physical environment theme, while the US performed strongly in the infrastructure themes. The comparative results of the US and Mexico illustrated that it is possible to achieve high levels of progress without an excessive reliance on high levels of production and income.     

Socio-economic status, permanent income, and fertility: a latent-variable approach

This paper examines how permanent income and other components of socio-economic status (SES) are related to fertility in less developed countries. Because permanent income cannot be measured directly, we employ a latent-variable method. We compare our results with those of the more common proxy-variable method and investigate the consequences of not accounting for measurement error. Using data from Ghana and Peru, we find that permanent income has a large, negative influence on fertility and that research must take the latent nature of permanent income into account to uncover its influence. Controlling for measurement error in the proxies for permanent income can also lead to substantial changes in the estimated effects of control variables. Finally, we examine which of the common proxies for permanent income most closely capture the concept. The results have implications beyond this specific dependent variable, providing evidence on the sensitivity of microanalyses to the treatment of long-term economic status.     

Prenatal Health,Educational Attainment,and Intergenerational Inequality: The Northern Finland Birth Cohort 1966 Study

In this article, we study the effects of prenatal health on educational attainment and on the reproduction of family background inequalities in education. Using Finnish birth cohort data, we analyze several maternal and fetal health variables, many of which have not been featured in the literature on long-term socioeconomic effects of health despite the effects of these variables on birth and short-term health outcomes. We find strong negative effects of mother’s prenatal smoking on educational attainment, which are stronger if the mother smoked heavily but are not significant if she quit during the first trimester. Anemia during pregnancy is also associated with lower levels of attained education. Other indicators of prenatal health (pre-pregnancy obesity, mother’s antenatal depressed mood, hypertension and preeclampsia, early prenatal care visits, premature birth, and small size for gestational age) do not predict educational attainment. Our measures explain little of the educational inequalities by parents’ class or education. However, smoking explains 12%—and all health variables together, 19%—of the lower educational attainment of children born to unmarried mothers. Our findings point to the usefulness of proximate health measures in addition to general ones. They also point to the potentially important role played by early health in intergenerational processes.     

Birth Registration in China: Practices,Problems and Policies

Data from interviews with staff of government offices, relevant literature and national statistics are used to analyze laws, regulations, rules, policies and operational procedures concerning birth registration in China. The current status of and existing problems with birth registration, as well as the influences of delayed birth registration on children’s rights and welfare are examined. Finally, barriers to birth registration in China are explored and strategies to improve the process of birth registration and to protect children’s rights are proposed. The main findings are as follows: First, the rate of birth registration in China is low and in rural areas and for marginalized children, it is even lower. Second, the dual birth registration system and interference from the Population and Family Planning department cause serious administrative difficulties. Third, the serious problems surrounding birth registration in China are a result of interactions among the interests of different stakeholders, while most stakeholders are unaware of the dimensions of the problems. Strategies and policies to promote birth registration are discussed.
