Gender Pay Gap and Employment Sector: Sources of Earnings Disparities in the United States, 1970–2010

Using data from the IPUMS-USA, the present research focuses on trends in the gender earnings gap in the United States between 1970 and 2010. The major goal of this article is to understand the sources of the convergence in men’s and women’s earnings in the public and private sectors as well as the stagnation of this trend in the new millennium. For this purpose, we delineate temporal changes in the role played by major sources of the gap. Several components are identified: the portion of the gap attributed to gender differences in human-capital resources; labor supply; sociodemographic attributes; occupational segregation; and the unexplained portion of the gap. The findings reveal a substantial reduction in the gross gender earnings gap in both sectors of the economy. Most of the decline is attributed to the reduction in the unexplained portion of the gap, implying a significant decline in economic discrimination against women. In contrast to discrimination, the role played by human capital and personal attributes in explaining the gender pay gap is relatively small in both sectors. Differences between the two sectors are not only in the size and pace of the reduction but also in the significance of the two major sources of the gap. Working hours have become the most important factor with respect to gender pay inequality in both sectors, although much more dominantly in the private sector. The declining gender segregation may explain the decreased impact of occupations on the gender pay gap in the private sector. In the public sector, by contrast, gender segregation still accounts for a substantial portion of the gap. The findings are discussed in light of the theoretical literature on sources of gender economic inequality and in light of the recent stagnation of the trend.

Sun Belt Rising: Regional Population Change and the Decline in Black Residential Segregation, 1970–2009

The goal of this study is to examine the extent to which population shifts over the post–Great Migration period and divergent trends in segregation across regions contributed to the overall decline in black segregation in the United States in recent decades. Using data from the 1970 to 2000 decennial censuses and the 2005–2009 American Community Survey (ACS), our analysis indicates that black dissimilarity and isolation declined more in the South and West than in the Northeast and Midwest. Nevertheless, regional population shifts account for only a modest amount (8 % to 12 %) of the decline in black-white segregation over the period and for an even smaller proportion of the decline in black-nonblack segregation, in part because the largest declines in segregation occurred in the West while the region with the largest relative increase in the black population was the South. Using more refined census divisions rather than census regions provided some additional explanatory power (shifts across divisions explained 15 %–16 % of the decline in black-white segregation): divisions with larger gains in their share of the black population tended to have larger declines in black segregation. Overall, although the effect of the regional redistribution of the black population on declines in segregation was significant, of even greater importance were other causes of substantial declines in segregation in a wide array of metropolitan areas across the country, and especially in the West, over the past 40 years.

The dynamics of the population sex ratio in India, 1971-96

This paper reconstructs the trend in the population sex ratio in India between 1971 ad 1996 from available information on changes in sex differentials in mortality in the country since the beginning of the century. It is estimated that, although the mortality of females relative to that of males in India has improved since 1968, the population sex ratio increased between 1971 and 1981, stayed constant between 1981 and 1991, and started to decrease only after 1991. This implies that the recorded decrease and increase in the periods 1971-81 and 1981-91 respectively were both spurious and were the results of undercounts of females in 1971 and 1991. Another implication of this finding is that, owing to the lagged effect of past mortality on current trends in the population sex ratio, this ratio is a bad proxy for use in the study of changes in differential mortality by sex.     

Sex Differentials in Mortality in the Soviet Union: Regional Differences in Length of Working Life in Comparative Perspective

In this paper we take a different approach from other authors to the study of differences between the mortality of the two sexes in the USSR. First, we use measures of mortality that are not sensitive to the most common types of error in data and that reflect experience in an age range that is important from a policy perspective: the working ages. Secondly, we measure variation in mortality between regions of the USSR. Thirdly, we compare these regional mortality trends with experience in 33 developed countries. The sex differential in mortality in the USSR is an amalgam of very different regional patterns. Its size and rate of change are more extreme in the USSR than in other countries, and are mainly due to the poor and rapidly worsening mortality of men in the Russian Republic. But the widening sex differentials and increasing mortality of men in the older working ages in Soviet regions are similar to trends in many other developed countries.     

Differentials in the femininity ratio among centenarians: variations between northern and southern Italy from 1870

Significant differentials have been observed between Italian regions in the distribution of centenarians by sex, from two women per man in the south to over eight in certain regions in the north. In order to explain these differentials we studied the evolution of the femininity ratio (FR), using a longitudinal approach to follow the ageing process in two cohorts, and making use of nearly all the statistical data available since the time of the Unification of Italy in 1870. Significant differentials in the FR observed at the age of 100 are mainly due to mortality differentials among men over the age of 60. The high mortality of men in the north and their low mortality in the south are the main explanations of why the FRs are higher in the north and lower in the south. Mortality differentials among women have only a marginal impact.     

Relationships between nuptiality and fertility: a case study on the Spanish Province of Navarre, 1786-1991

In this article we analyse the influence of age at marriage and percentage of definitive celibacy on marital and total fertility over the past two hundred years in the Spanish province of Navarre. A considerable percentage of the fall in marital fertility in the first half of the twentieth century in rural Navarre was due to the postponement in women's age at marriage. On the other hand, Navarre offers many exceptions to the scenario often endorsed by researchers that sees marriage as the prime mechanism for regulating reproduction in traditional societies. While in the northern part of the province this mechanism did bring about the reduction of total fertility, in the southern part the fall was primarily a consequence of a fall in marital fertility.     

Five decades of missing females in China

This paper seeks to explain the dearth of females in the population of China in cohorts born from the late 1930s to the present. We demonstrate that in virtually all cohorts. the shortage of females in comparison with males is revealed when the cohort is first enumerated in a census. Subsequently it barely changes, an indication that female losses occur very early in life. Using the high-quality data from the censuses and fertility surveys in China, we show that many of the births of the girls missing in the censuses were not reported in the surveys because they died very young. The incidence of excess early female mortality (probably infanticide) declined precipitously in the Communist period, but not to zero. The recent escalation in the proportion of young females missing in China has been caused largely by rapidly escalating sex-selective abortion.

Fertility in urban areas of Mexico: Implications for the theory of the demographic transition

Recent investigations indicate that fertility is not universally associated with urbanization and economic development in the manner predicted by the theory of the demographic transition. It is possible, however, that these investigations only partially test the theory, for the degree of industrialization in urbanareas is rarely taken into account. Two hypotheses are tested based upon Mexican census and vital registration data for 1940-60: (a) urban fertility is inversely related to the proportion of the urban population employed in the secondary sector of the economy and (b) changes in urban fertility are inversely related to changes in the proportion of the urban population employed in the secondary sector of the economy.At each census date from 1940 to 1960, the association between urban fertility (age-standardized child-woman ratio adjusted for infant mortality) and the percent in the secondary sector is low and positive. In 1960, however, the association is negative (suggesting a possible change in the direction of the association), but city growth rates and the proportion of females married are more closely related to fertility than percent in the secondary sector. Hypothesis a, then, receives little support from the data.Much the same is true of hypothesis b. The association between changes in urban fertility and changes in the percent in the secondary sector is positive. Moreover, city growth rates and changes in the proportion literate explain more of the variation in fertility change than does the percent in the secondary sector.In addition, over-all fertility has risen since 1940, and this rise is pronounced in large urban areas. It is suggested that among certain segments of Mexican society, the response to economic development has been an increase rather than a reduction in fertility. It is further suggested that if city growth is indicative of rural-urban migration, the presence of large numbers of rural migrants in urbanareas may help to explain the decreasing size of the urban-rural fertility differential in Mexico.If this interpretation is correct, the theory of the demographic transition is in need of further modification, specification, and verification.

Demographic change,rising earnings inequality,and the distribution of personal well-being, 1959–1989

This paper uses new methods to determine the sources of the sharp fall and then the steep rise in personal income inequality between 1959 and 1989. The increase in the proportion of single-head families tended to boost inequality over the entire period. Forty percent of the reduction in income inequality in the 1960s occurred because of the decline in earnings inequality among male heads of families; more than one-third of the increase in inequality after 1969 occurred because inequality in male earnings soared. Since 1979 females’ gains in earnings have increased inequality because these gains have been concentrated increasingly in families with high incomes     

AGING,RETIREMENT AND SOCIAL SECURITY IN A MODEL OF INTEREST GROUPS

The assessment of the degree of genetic variation in a natural population, and the nature of that variation, is of central importance in both theoretical and applied population studies. Two “variance” results in population genetics theory are presented. For the first, expressions are found for the expected difference in the estimates of genetic variation in a population obtained by two investigators sampling from the same population in the same generation. The second result concerns the question of whether the degree of genetic variation in a population is best estimated by using the number of alleles observed in a sample of genes or by the number of polymorphic sites observed in the sample. For some combinations of the actual degree of variation and the sample size the former is preferred while for other combinations the latter is preferred. The reason for this is discussed.     

Social structure and U.S. inter-state fertility differentials in 1900

This paper investigates the importance of agricultural land shortages versus modernization of the society in influencing inter-state differentials in fertility in 1900, when the United States was in midtransition. Urbanization and manufacturing characteristics of states were the strongest correlates of variations in the index of total fertility because urban-industrialism depressed both the probability of marriage and marital fertility. Other modern characteristics of American states were also important in understanding variations in marital fertility. Low labor force employment of children and farm mechanization, integrally related characteristics, seemed to depress levels of marital fertility in many parts of the United States, independent of the urban-industrial system. Agricultural land opportunity had little overall effect on marital fertility; however, it was quite important in understanding variations in patterns of marriage.     

北京市流动人口的最新状况与分析

本文根据2006年“北京市1‰流动人口调查”数据分析了北京市流动人口的结构、分布、经济状况和居住状况等特征。研究发现,北京市流动人口正在发生结构性的变化,其家庭化的趋势明显;北京的经济优势是吸引流动人口来京的最主要原因;流动人口在京滞留时间较长,很多人已经成为事实上的“北京人”;流动人口的流动渠道和实现就业的渠道具有“非正规”的特性;流动使绝大多数人实现了职业身份的“非农化”,但在进城后流动劳动力继续向上流动的机会减少。另外,本文也探讨了在京流动人口在劳动就业、社会保险、居住条件等方面面临的困境和问题。     

A census-based analysis of the economic status of older indigenous Australians

The focus of this paper is the educational and economic status of indigenous Australians aged 50 years and over as reported in the 1991 Population Census. These indigenous people were less likely to be in employment than other Australians in the same age group and were more likely to be in unskilled occupations. Although there was no evidence of an improvement in the relative individual incomes of indigenous people in this age group between 1986 and 1991, there was some evidence of gains relative to other Australians in the share of the population in employment. This probably reflects the expansion of the Community Development Employment Projects (CDEP) scheme and as such should not be taken as an indicator of growth in indigenous employment independent of government support.     

Assessment of ASEAN population programme

The objectives of the 5th meeting of the ASEAN Heads of Population Program, held at Chiang Mai during November 1981, were the following: to discuss and consider the midterm reviews of some of the Phase 1 projects; to discuss and consider the ASEAN population experts' views on the progress made in the rest of the phase 1 projects; to discuss and consider the progress made in the implementation of the phase 2 projects; to discuss and consider the ASEAN population experts' recommendations on the ASEAN population program in the 1980s based on the report of the programming exercise submitted by the consultant in the expert group meeting; and to discuss administrative and other problems faced by the program implementors in the operationalization of the ongoing ASEAN population projects and provide appropriate directions to solve such problems. As a result of the programming exercise, the meeting established the directions for the future ASEAN population program and strongly recommended the continuation, intensification, and expansion of the ASEAN population program. A total of 12 projects comprise the ASEAN population program: 5 projects under phase 1 and 7 under phase 2. Under phase 1, 1 project has been completed, and the 1st parts of 2 other projects are in the process of implementation. Phase 2 projects, which started in September/October 1980, are all in the process of implementation. The following phase 1 projects are summarized: integration of population and rural development policies and programs; modular training for trainers of population and development agencies in ASEAN countries; multi-media support for population programs in the context of rural development in ASEAN countries; and migration in relation to rural development. The following phase 2 projects are also summarized: institutional development and exchange of personnel; women in development in ASEAN countries; and migration in relation to rural development. The following phase 2 projects are also summarized: institutional development and exchange of personnel; women in development; developing and strengthening national population information systems and networks in ASEAN countries; population and development dynamics and the human resource balance; studies on health and family planning in ASEAN countries; development of ASEAN social indicators; and population migratory movement and development.
