Traditional measures of poverty are informative in indicating the degree of economic deprivation in a population at a cross-sectional point in time, but they do not consider growth in the size of the non-poverty population. We develop a measure of non-poverty population growth in order to explore whether it constitutes a useful indicator of an important demographic dynamic. We illustrate our approach with an analysis of the U.S. states using Census and American Community Survey data from 1990, 2000, and 2010. The results indicate that the extent to which the non-poor population increased across states is uncorrelated with the initial poverty rate as conventionally measured. Broken down by nativity, the findings further show that some states with official poverty rates above the national average (e.g., Arizona, Georgia, and Texas) nonetheless had some of the highest rates of non-poor population growth among less skilled immigrants. By contrast, other states with official poverty rates below the national average (e.g., Connecticut, New Hampshire, and Vermont) often had low rates of non-poor population growth among less skilled immigrants. These findings suggest that low initial poverty rates do not necessarily contribute substantially to the alleviation of global poverty through the immigration of less skilled persons from less developed nations. However, the rate of non-poor population growth among less skilled immigrants also appears to be uncorrelated with state variation in minimum wages even after taking into account population density and median home value.  相似文献

While union density in the public sector has increased in recent decades, private sector union density in the U.S. has declined steadily since the mid-1950s. Scholars have evoked a variety of explanations to account for the decline in union membership, but substantially less attention has been devoted to understanding the contribution of the union organizing process as governed by the National Labor Relations Board (NLRB). In this paper, we focus on two aspects of this process: union organizing effort (the effort to establish union representation elections to organize non-unionized workers) and union organizing success (success in winning union representation elections). Using annual time series data for the U.S. from 1948 to 2004, we show that there has been a long-term decline in both union organizing effort and union organizing success, which likely contributes to declining union density. We focus on three explanations for these changes: the political–legal environment for unions, deindustrialization and globalization, and employer opposition to unionization efforts. We find that each of these factors contributes to organizing effort and success and conclude with a discussion of the implications of this research for future mobilization efforts.  相似文献

Immigrant residential segregation in U.S. metropolitan areas, 1990–2000   总被引:2,自引:0,他引:2  
This paper examines the extent of spatial assimilation among immigrants of different racial and ethnic origins. We use restricted data from the 1990 and 2000 censuses to calculate the levels of dissimilarity by race and Hispanic origin, nativity, and year of entry, and then run multivariate models to examine these relationships. The findings provide broad support for spatial assimilation theory. Foreign-born Hispanics, Asians, and blacks are more segregated from native-born non-Hispanic whites than are the U.S.-born of these groups. The patterns for Hispanics and Asians can be explained by the average characteristics of the foreign-born that are generally associated with higher levels of segregation, such as lower levels of income, English language ability, and home ownership. We also find that immigrants who have been in the United States for longer periods are generally less segregated than new arrivals, and once again, much of this difference can be attributed to the characteristics of immigrants. However, patterns also vary across groups. Levels of segregation are much higher for black immigrants than for Asian, Hispanic, and white immigrants. In addition, because black immigrants are, on average, of higher socioeconomic status than native-born blacks, such characteristics do not help explain their very high levels of segregation.  相似文献

In this article, we assess trends in residential segregation in the United States from 1960 to 2000 along several dimensions of race and ethnicity, class, and life cycle and present a method for attributing segregation to nested geographic levels. We measured segregation for metropolitan America using the Theil index, which is additively decomposed into contributions of regional, metropolitan, center city-suburban, place, and tract segregation. This procedure distinguishes whether groups live apart because members cluster in different neighborhoods, communities, metropolitan areas, or regions. Substantively, we found that the segregation of blacks decreased considerably after 1960 largely because neighborhoods became more integrated, but the foreign born became more segregated largely because they concentrated in particular metropolitan areas. Class segregation increased between 1970 and 1990 mainly because the affluent increasingly clustered in specific metropolitan areas and in specific municipalities within metropolitan areas. The unmarried increasingly congregated in center cities. The main purpose of this article is to describe and illustrate this multilevel approach to studying segregation.  相似文献

At the time of entry into the U.S., immigrants are required to identify their ’intended’ destination to INS officials. They are not, however, required to remain in that location. If immigrant settlement patterns represent an evolutionary, dynamic system, it is likely that immigrants will adjust their location in the period shortly after arrival in the U.S. in response to various factors, leading to an ‘initial’ settlement system. Of interest in the following paper are the scale, direction and magnitude of adjustments made to the immigrant settlement system in the period shortly after arrival. The analysis utilizes the 1990 5 percent Public Use Microdata Sample (PUMS) and the 1985–90 Immigration and Naturalization Service (INS) Public Use Tapes in order to explore the intended and initial (observed) settlement patterns of recent (1985–90) immigrants and to comment upon the applicability of these terms. Results indicate that the two settlement patterns are highly similar, despite apparently high levels of movement among recent arrivals. The analysis also touches upon the ‘come to stay’ question raised by Ellis and Wright (1998a), suggesting that the interpretation of the question is dependent upon immigrant status rather than when immigrants first arrived in the U.S. This research was funded by a grant from the National Science Foundation (97-08436).

Between 1994 and 2006, the ratio of foreign-born scientists and engineers (FSE) to native scientists and engineers (NSE) doubled. I decompose this change into a migration effect (which accounts for migration in general), a proportional college effect (which accounts for the relative proportions of college graduates among migrant and native workers), and a proportional science and engineering (S&E) effect (which accounts for the relative proportions of S&Es among migrant and native college-educated workers). Results show that the migration effect explains about three-quarters of the increase in FSE/NSE during the entire period under study. The proportional S&E effect, which captures changes in the ratio as a result of immigration of S&Es in excess of what would be expected from general migration alone, was largest in 1995–1998, which were years of sustained economic growth. Conversely, a slower economy coincided with a declining proportional S&E effect after 2000. Increases in the annual cap on H-1B visas, an important avenue of entry for foreign-born S&Es, had little effect on the ratio. In short, during 1994–2006, the association between economic swings and the specific, more than proportional migration of S&Es was much stronger than the association between the latter and changes in the H-1B cap.  相似文献

Using data from the U.S. Bureau of Justice Statistics and Census Bureau, I estimate death rates of working-age prisoners and nonprisoners by sex and race. Incarceration was more detrimental to females in comparison to their male counterparts in the period covered by this study. White male prisoners had higher death rates than white males who were not in prison. Black male prisoners, however, consistently exhibited lower death rates than black male nonprisoners did. Additionally, the findings indicate that while the relative difference in mortality levels of white and black males was quite high outside of prison, it essentially disappeared in prison. Notably, removing deaths caused by firearms and motor vehicles in the nonprison population accounted for some of the mortality differential between black prisoners and nonprisoners. The death rates of the other groups analyzed suggest that prison is an unhealthy environment; yet, prison appears to be a healthier place than the typical environment of the nonincarcerated black male population. These findings suggest that firearms and motor vehicle accidents do not sufficiently explain the higher death rates of black males, and they indicate that a lack of basic healthcare may be implicated in the death rates of black males not incarcerated.  相似文献

This study examines casualties from tornadoes in the United States between the years 1998 and 2000. A political model of human ecology (POET) was used to explore how the environment, technology, and social inequality influence rates of fatalities and injuries in two models. Data were drawn from four sources: John Hart's Severe Plot v2.0, National Weather Service (NWS) Warning Verification data, Storm Prediction Center (SPC) watch data, and tract-level census data. Negative binomial regression was used to analyze the causes of tornado fatalities and injuries. Independent variables (following POET) are classified in the following manner: population, organization, environment, and technology. Rural population, population density, and household size correspond to population; racial minorities and deprivation represent social organization; tornado area represents environment; and tornado watches and warnings, as well as mobile homes, correspond to technology. Findings suggest a strong relationship between the size of a tornado path and both fatalities and injuries, whereas other measures related to technology, population, and organization produce significant yet mixed results. Census tracts having larger populations of rural residents was, of the nonenvironmental factors, the most conclusive regarding its effects across the two models. The outcomes of analysis, although not entirely supportive of the model presented in this study, suggest to some degree that demographic and social factors play a role in vulnerability to tornadoes.  相似文献

Using large nationally representative longitudinal data on changes in happiness and mortality and multivariate increment–decrement life tables, we assess length of quality life through cohort estimates of happy life expectancies. We examine population-based and status-based life expectancies in absolute term of years and relative term of proportions. We find that happy life expectancies exceed unhappy life expectancies in both absolute and relative terms for the overall population and population in each state of happiness at any given age. Being happy (as opposed to unhappy) at any age brings a longer life and more of the future life spent in happiness. We also examine social differentials in the estimates of happy life expectancy at each age by sex, race, and education. The educational gap in happy life expectancies is larger than the sex and race gaps. For the better educated, longer life consists of a longer happy life and shorter unhappy life in both years and proportions and regardless of happy or unhappy status at any given age.  相似文献

Chinese population statistics are collated from the time of the Western Han Dynasty (A.D. 2) to 19 5 3, including statistics of population and households for provinces as well as for China as a whole. Evidence bearing on the definitions of the statistics, methods of compilation, and reliability of the figures as measures of population size and change, is summarized. An "emended series " of population totals for China proper, A.D. 2 to 1953 is presented, excluding figures which are clearly defective.  相似文献

In this paper, I examine temporal changes in U.S. adult mortality by chronic disease cause of death and by sex over a 40-year period in the second half of the twentieth century. I apply age-period-cohort (APC) analyses that combine conventional approaches and a new method of model estimation to simultaneously account for age, period, and cohort variations in mortality rates for four leading causes of deaths, including heart disease, stroke, lung cancer, and breast cancer. The results show that large reductions in mortality since the late 1960s continued well into the late 1990s and that these reductions were predominately contributed by cohort effects. Cohort effects are found to differ by specific causes of death examined, but they generally show substantial survival improvements. Implications of these results are discussed with regard to demographic theories of mortality reductions, differential cohort accumulation of health capital and lifetime exposures to socioeconomic and behavioral risk factors, and period changes in diagnostic techniques and medical treatment.  相似文献

An increment-decrement stochastic-process life table model that continuously mixes measures of functional change is developed to represent age transitions among highly refined disability states interacting simultaneously with mortality. The model is applied to data from the National Long Term Care Surveys of elderly persons in the years 1982 to 1996 to produce active life expectancy estimates based on completed-cohort life tables. At ages 65 and 85, comparisons with extant period estimates for 1990 show that our active life expectancy estimates are larger for both males and females than are extant period estimates based on coarse disability states.  相似文献

This study compares trends in work–family context by education level from 1976 to 2011 among U.S. women. The major aim is to assess whether differences in work–family context by education level widened, narrowed, or persisted. We used data from the 1976–2011 March Current Population Surveys on women aged 25–64 (n = 1,597,914). We compare trends in four work–family forms by education level within three race/ethnic groups. The work–family forms reflect combinations of marital and employment status among women with children at home. Trends in the four work–family forms exhibited substantial heterogeneity by education and race/ethnicity. Educational differences in the work–family forms widened mainly among white women. Compared with more-educated peers, white women without a high school credential became increasingly less likely to be married, to be employed, to have children at home, and to combine these roles. In contrast, educational differences in the work–family forms generally narrowed among black women and were directionally mixed among Hispanic women. Only one form—unmarried and employed with children at home—became more strongly linked to a woman’s education level within all three race/ethnic groups. This form carries an elevated risk of work–family conflict and its prevalence increased moderately during the 35-year period. Taken together, the trends underscore recent calls to elevate work–family policy on the national agenda.  相似文献

A general index of social, economic, and political threat in Europe and Belgium was developed for the years 1920 to 1993. We asked 91 Belgian historians, experts in contemporary history, to rate, on 7-point intensity scales, the extent to which each year, between 1920 to 1993, the security and existence of either Europe or Belgium was threatened. In making their judgments, the historians must integrate most of the information contained in objective data known to them as causes of fear (crime, unemployment, apprehension at starting a family, buying a car, or starting a new business, etc.). The present threat index rests on a synthetic judgment because many official objective data available to historians either are incomplete or lack conceptual coherence. The index obtained has then been compared to known objective indicators of social, economic, or political threat. We obtained Cronbach's coefficients of 0.99 for Belgian historians. Corrected for serial dependency, the threat index for Belgium is found to depend on a 5-variable subset composed of: suicide, unemployment, and balance of trade, for the positive associations; and GNP and car registrations, for the negative associations. The Pearson correlation between the threat index for Europe and Belgium is 0.95 (N = 74, p < 0.001). Just as McCann and Stewin (1990) had developed a similar tool for North America, the aim of this multi-purpose tool was to monitor the mood of Europe and Belgium over time based on evaluations made by professional historians. McCann and Stewin's (1990) threat index for the US has a Pearson correlation of 0.65 (N = 67, p < 0.001) with the European threat index. The article concludes with a discussion first on the question of the role of threat producing discourses in the perception of threat, and second, on the question of Europe as a concept.  相似文献
