White Residential Segregation in U.S. Metropolitan Areas: Conceptual Issues, Patterns, and Trends from the U.S. Census, 1980 to 2010

Racial and ethnic diversity continues to spread to communities across the United States. Rather than focus on the residential patterns of specific minority or immigrant groups, this study examines changing patterns of White residential segregation in metropolitan America. Using data from the 1980 to 2010 decennial censuses, we calculate levels of White segregation using two common measures, analyze the effect of defining the White population in different ways, and, drawing upon the group threat theoretical perspective, we examine the metropolitan correlates of White segregation. We find that White segregation from others declined significantly from 1980 to 2010, regardless of the measure of segregation or the White population used. However, we find some evidence consistent with the group threat perspective, as White dissimilarity is higher in metro areas that are more diverse, and especially those with larger Black populations. Nevertheless, our findings indicate that Whites having been living in increasingly integrated neighborhoods over the last few decades, suggesting some easing of the historical color line.

Segregation and Social Welfare: A Methodological Proposal with an Application to the U.S.

The aim of this paper is twofold: (a) to define a new concept, the welfare loss that a society experiences due to the segregation of the demographic groups that comprise it and (b) to propose measures that quantify this phenomenon satisfying a set of normative properties. In aggregating the well-being losses (gains) of the groups derived for being concentrated in low-status (high-status) organizational units, this paper embraces the distributive approach adopted in the literature on economic deprivation and poverty. The advantages of these measures are shown by exploring the welfare losses that the United States has experienced from 1980 to 2012 due to occupational segregation by both gender and race/ethnicity. Our analysis shows that our measures reveal certain aspects of the phenomenon that do not emerge when using overall segregation measures. Thus, for example, while nothing seems to have changed in U.S. labor market in the last decade according to some well-known overall segregation measures, the social welfare loss due to segregation has actually increased.     

Preprocessing the 1960–1970 U. S. census public use samples

This is a report on computer programming undertaken to preprocess the 1960–1970 U. S. census public use samples to increase their accessibility. This includes wholesale recoding into positive integers from 1 to N, with 0 reserved for “not applicable”, combining household and person records, sorting records into ten 1/10,000 samples, compacting binary codes to fit on a single reel of tape, and the production of a revised set of formatted tapes.     

Hypersegregation in U.S. Metropolitan Areas: Black and Hispanic Segregation Along Five Dimensions

Residential segregation has traditionally been measured by using the index of dissimilarity and, more recently, the P* exposure index. These indices, however, measure only two of five potential dimensions of segregation and, by themselves, understate the degree of black segregation in U.S. society. Compared with Hispanics, not only are blacks more segregated on any single dimension of residential segregation, they are also likely to be segregated on all five dimensions simultaneously, which never occurs for Hispanics. Moreover, in a significant subset of large urban areas, blacks experience extreme segregation on all dimensions, a pattern we call hypersegregation. This finding is upheld and reinforced by a multivariate analysis. We conclude that blacks occupy a unique and distinctly disadvantaged position in the U.S. urban environment.     

Annexation as a factor in the growth of U.S. cities, 1950–1960 and 1960–1970

The incidence of annexation, the growth in the original area and in the area annexed, and the proportion of growth due to annexation between 1950 and 1970 are analyzed for U.S. cities grouped by size, metropolitan status, and region of the country. Over this period, annexation was a principal means of population growth for incorporated places outside the Northeast. Though often associated with metropolitan growth, annexation was even more important in the growth of nonmetropolitan cities. Overall growth differences by size of place, metropolitan status, and decade (1950--1960 or 1960--1970) could not be explained by the incidence and nature of annexation.     

Intergenerational Neighborhood Attainment and the Legacy of Racial Residential Segregation: A Causal Mediation Analysis

Advances in mediation analysis are used to examine the legacy effects of racial residential segregation in the United States on neighborhood attainments across two familial generations. The legacy effects of segregation are anticipated to operate through two primary pathways: a neighborhood effects pathway and an urban continuity pathway. The neighborhood effects pathway explains why parent’s exposure to racial residential segregation during their family-rearing years can influence the residential outcomes of their children later in life. The urban continuity pathway captures the temporal consistency of the built and topographical environment in providing similar residential opportunities across generations. Findings from the Panel Study of Income Dynamics and U.S. Census data indicate that the legacy effect of racial residential segregation among black families operates primarily through the neighborhood effects that influence children growing up. For white families, there is less support for the legacy effects of segregation. The findings are supported by a comprehensive mediation analysis that provides a formal sensitivity analysis, deploys an instrumental variable, and assesses effect heterogeneity. Knowledge of the legacy of segregation moves neighborhood attainment research beyond point-in-time studies of racial residential segregation to provide a deeper understanding into the ways stratified residential environments are reproduced.     

U.S. Hispanics: A demographic and issue profile

This paper highlights sociodemographic characteristics of Hispanics and extrapolates issues attendant to this large and growing segment of American society. Educational, political, and economic issues are considered.This article was presented at the 40th California History Institute sponsored by the Holt-Atherton center for Western Studies, the University of the Pacific, Stockton, California, April 24–25, 1987.     

Urban Quality of Life: A Case Study of Guwahati

This paper studies quality of life (QOL) in urban environment. The term environment has been used in broader sense, which includes physical, social and economic environment. A framework has been proposed which posits that QOL comprises objective condition of living and satisfaction from such living condition constitutes QOL. Such objective condition refers to objective QOL and satisfaction refers to subjective QOL. Dimension of QOL has been found to be multi dimensional. It has been found that both objective and subjective condition is important dimension of QOL. But correlation between objective and subjective QOL has been found not to be high. At the same time it has been found that satisfaction from condition of traffic is the lowest among all satisfaction variables.     

Immigration and environmental emissions: A U.S. county-level analysis

This paper investigates the immigration–environment association using U.S. county-level data, for a subset of counties (N = ~200), and a model inspired by the STIRPAT approach. The analysis makes use of U.S. census data for the year 2000 reflecting U.S.-born and foreign-born populations, combined with county-level data reflecting emissions of CO₂, NO₂, PM₁₀, and SO₂. With a focus on approximately 200 primarily urban counties for which complete data are available, and after controlling for income, employment in the utilities and manufacturing sectors, and coal consumption for SO₂ estimations, few statistically significant associations emerge between population composition and emissions. Counties with a relatively larger U.S.-born population have higher NO₂ and SO₂ emissions. On the other hand, counties with a relatively higher number or share of foreign-born residents have lower SO₂ emissions. Although limited to cross-sectional analyses, the results provide a foundation for future longitudinal research on this important and controversial topic.     

The 1960s: A decade of progress for blacks?

Between 1960 and 1970 blacks, as well as whites, improved their socioeconomic status. Among both races, educational attainment increased, the occupational distribution was upgraded, and real purchasing power rose markedly. In almost every comparison, the gains were somewhat greater among blacks than among whites and thus most indicators of racial differentiation declined. Nevertheless, the changes of this decade failed to eliminate racial differences with regard to socioeconomic status. In all comparisons, except for the income of certain groups of women, blacks were at a disadvantage when compared to whites both at the start and at the end of this decade, and very large racial differences remain. Further socioeconomic progress by blacks during the 1970s will probably not eliminate racial differences. The article concludes by relating the socioeconomic trends to such other aspects of race relations as integration, governmental policy, and the attitudes of whites and blacks.     

The age pattern of first-birth rates among U.S. women: The bimodal 1990s

Between 1990 and 2002, the age pattern of Type I first-birth rates (i.e., the hazard of a first birth) among U.S. women was bimodal. This pattern, driven by changing differential fertility patterns among racial and ethnic groups, reached its apex at the mid-1990s and had almost vanished by the decade's end. Research on first-birth timing has tended to focus on Type II first-birth rates and therefore has failed to identify this larger, bimodal pattern. This article presents the benefits of using Type I rates, documents the emergence of the bimodal pattern via two new measures of bimodality, and uses a decomposition analysis to discuss the pattern's causes.     

Residential Integration on the New Frontier: Immigrant Segregation in Established and New Destinations

This article explores patterns and determinants of immigrant segregation for 10 immigrant groups in established, new, and minor destination areas. Using a group-specific typology of metropolitan destinations, this study finds that without controls for immigrant-group and metropolitan-level characteristics, immigrants in new destinations are more segregated and immigrants in minor destinations considerably more segregated than their counterparts in established destinations. Neither controls for immigrant-group acculturation or socioeconomic status nor those for demographic, housing, and economic features of metropolitan areas can fully account for the heightened levels of segregation observed in new and minor destinations. Overall, the results offer support for arguments that a diverse set of immigrant groups face challenges to residential incorporation in the new areas of settlement.     

Volunteering for Human Service Provisions: Lessons from Italy and the U.S.A.

The increased reliance on volunteers in all industrialized democracies has been parallelled by growing fiscal crises in most states, widespread criticism of welfare, and increased demand for social services. While volunteer work is presumed to be an alternative to public services, its feasibility is not yet clear. We suggest that a cross-national comparison of two significantly different countries would provide more information about volunteerism as a partial substitute for public services. We compared the United States where volunteerism is a widespread tradition and Italy where there has been a “rediscovery” of volunteerism since the 1980s. Differences between the two countries in the practice of volunteerism are examined from several perspectives. They include the relationships between volunteers and the statutory sector, the professionalization of volunteer activity, the role of citizen participation in a capitalistic society, and the Lockean principle of limited government. Finally, we conclude that while there are many differences in welfare provision between the United States and Italy, they do have a common element: increased reliance on volunteers for every aspect of day-to-day life; however, this reliance is mostly ideologically-based and may prove unfounded and costly.     

Immigration to the U.S.: the unfinished story

Annual totals of new immigrants and refugees in the US may now be up to the record highs of over a million immigrants counted in 6 years between 1905 and 1914. Since 1979, legal immigrants have averaged 566,000 a year (570,009 in 1985), newly arrived refugees and asylees approved have averaged 135,000, and the "settled" illegal immigrant population is growing by up to 1/2 million a year, according to some estimates. 1/2 of illegal immigrants are persons who entered the US legally but then overstayed the terms of temporary visas. Immigration and Naturalization Service apprehensions of illegal aliens, projected at a record 1.8 million for fiscal year 1986, indicate a sharp increase in illegal border crossers, driven by Mexico's and Central America's mounting population and economic pressures and lured by the prospect of jobs with employers who through a loophole in US immigration law can hire illegal aliens without penalty. The Census Bureau estimates that net immigration now accounts for 28% of US population growth and will account for all growth by the 2030's if fertility stays at the current low 1.8 births per woman. Public opinion strongly favors crubs on illegal immigration and legalization of illegal aliens long resident in the US, and in 1986 Congress enacted legislation to reduce illegal immigration to the US. Asians and Latin Americans now make up over 80% of legal immigrants and Latin Americans comprised 77% of illegal immigrants counted in the 1980 census. Asians far outstrip Latin American immigrants in education, occupational status, and income and might be expected to assimilate in the same manner as earlier immigrant group did. Hispanic immigrants so far appear to favor cultural pluralism, maintaining their own culture and the Spanish language. Research in California indicates that recent Hispanic immigrants (legal and illegal) have helped preserve low-wage industries and agriculture. Illegal immigrants appear to draw more on public health and education services than they pay back in taxes. With or without immigration reform, population and economic pressures in Mexico and the Caribbean Basin ensure that the numbers of people seeking to enter the US are only likely to increase.     

Delayed childbearing in the U.S.: facts and fictions

Between 1970-82, the proportion of 1st births in the US to women 25 and older rose from 19-36% and the proportion of women still childless at ages 25-34 increased by 56% at about the same time. Although a sharp contrast with the baby boom era of the 1950s and 1960s, todays's epidemic of delayed childbearing is similar to patterns earlier in the 20th century. As then, much is due to delayed age at marriage, but baby boomers now in the their late 20s and early 30s are also delaying childbirth after marriage. The trend stems in part from their economic difficulties as they compete in a tight job market caused both by their large numbers and a turbulent economy. But it is also related to women's increasing education and, in turn, increasing opportunities in and commitment to the labor force, which can be expected to encourage a delayed childbearing even after prospects brighten for young people. Although a diverse group, most of today's delayed childbearers are white, highly educated, 2-career couples. Adequate daytime care for preschool children is a prime concern. Although more employers now offer childcare assistance and flexible work schedules to working parents, the juggle between jobs and childraising can be a strain. On the plus side are delayed childbearers' greater maturity and generally higher incomes, which can ease potential problems created by parent-child age differences as their children grow up. Businesses have been quick to respond to the new market of older, affluent, 1st-time mothers. New methods of treating of circumventing infertility and prenatal detection of chromosomal birth defects can now help overcome potential biological problems that may concern women who choose to delay childbearing past age 30.     

Contraceptive sterilization in the U. S.: 1965 and 1970

There was an impressive increase between 1965 and 1970 in the prevalence of contraceptive sterilization, an increase that accelerated in the later years of the period and was shared in by virtually all subgroups considered. Among couples in 1970 for whom sterilization had been an option (recognizing that it is a terminal method), about one of every five had chosen this method of contraception. About half of all sterilizations were vasectomies, though vasectomies have outnumbered tubal ligations in recent years. Differentials in prevalence and in increases during 1965–1970 are reported for a number of life-cycle and social variables. In addition, a profile of the contraceptive sterile is presented for recent sterilizations. Significant proportions are relatively young and of low parity at the time of sterilization. In the context of the continued diffusion of the pill and IUD and increases in legal abortion, the net demographic effect of increasing sterilization is regarded as low, though sterilization is an important component of an effective fertility control regime.     

A century of U.S. censuses and the language characteristics of immigrants

Since 1890, every U.S. census but one has asked about the language characteristics of the U.S. population. This almost uninterrupted data series, however, has been shaped by contemporaneous presumptions about the ties between language and ethnicity, the likelihood of proficiency in English among various subgroups, and practical constraints. I describe shifts across censuses in the phrasing of questions about language, the coding of responses, and the subpopulations for which the questions were asked and the results were published. I then describe the data generated by these items and discuss their interpretation. I conclude with a summary of the major insights and limitations of a century's worth of data.
