A revised socioeconomic index of occupational status

Duncan's Socioeconomic Index (SEI), a widely used indicator of occupational ranking, is based on education and income data from the 1950 census. The major purpose of this paper is to offer a more contemporary version of this index. There are several reasons for doing so. Not only has the occupational classificatory scheme been altered, but the educational and economic characteristics of the American labor force and of specific occupational groups have changed since 1950. The two decades may also have seen a shift in the relations between the educational and economic attributes of an occupational grouping and its social standing or prestige. Second, the construction of the original SEI rested on the characteristics of the male labor force, rather than those of the total labor force. Third, in the process of updating the index, we illustrate how certain arbitrary decisions (dictated by data limitations) in the construction of the Duncan SEI served to vest the socioeconomic index with some artifactual properties. In the production of an updated version of the socioeconomic index, we use three approaches. First, we experiment with differing measures of the income and educational criteria. Second, we reconstruct the dependent variable, occupational standing, to provide a better approximation of the prestige measure used by Duncan (1961). Third, we consider the attributes of both the male and total labor forces in generating contemporary indexes of occupational status. We also compare the performance of the new socioeconomic indexes in models of occupational attainment against the performance of the original Duncan index and subsequent occupational prestige measures. The paper appends new socioeconomic indexes for detailed occupational titles based on the 1970 census classification of occupations.     

Do females necessarily have the same occupational status scores as males? A conceptual and empirical examination of the Duncan Socioeconomic Status Index and Nam-Powers Occupational Status Scores

Social Science researchers have advanced important yet somewhat contradictory conclusions regarding the different economic and occupational reward structures faced by men and women. Income and wage differences between men and women have been shown to be sizable and persistent throughout the occupational hierarchy. Conversely, gender differences in occupational status, commonly scaled by the Duncan Socioeconomic Index, have been shown to be small or nonexistent in most studies. In an attempt to investigate this incongruity, the present study undertakes a comparison of the Duncan SEI and the Nam-Powers Occupational Status Scores in an empirical study of the occupational position of white men and women in 65 large standard metropolitan statistical areas (SMSAs) in 1970. While the findings of earlier studies showing no gender differences in occupational status are for the most part replicated using the Duncan SEI, use of the Nam-Powers scores prompts a much different conclusion. Large status differences between men and women are indicated using this latter scale, differences which are very much in line with income differences commonly cited. We suggest that the Nam-Powers metric should be used instead of the Duncan SEI in studies of occupational status of women and men.     

Occupational stratification,job-mismatches,and child poverty: Understanding the disadvantage of Black immigrants in the US

This study examines the implications of occupational stratification and job mismatches for the welfare of children, using data from the 2005–2009 American Community Survey. The results show that Black children of immigrants have household heads that are more likely to have occupations with low SEI scores than children in US-born households. More importantly, they demonstrate that intersections between parental job-mismatches and employment in the bottom rather than upper levels of the occupational distribution have important implications for understanding poverty differences among children. Job mismatches within occupations with low SEI scores are associated with greater poverty risks among Black than White, Asian, or Hispanic children of immigrants. However, racial poverty disparities are considerably lower among children with household heads in the highest occupational strata.     

Trends in the relative occupational status of African Americans and European immigrants in Northern cities, 1880–1970

In his classic book, A Piece of the Pie, Stanley Lieberson described divergent trends in occupational standing for African Americans and European immigrants after 1920, as the Great Migration from the South swelled the size of the black population in northern cities. In this paper I build upon Lieberson’s work using longitudinal data drawn from the Integrated Public Use Microdata Series for the census years 1880–1970. This more versatile data source allows me to examine separate occupational trends for northern-born blacks and southern-born migrants and to control for relevant socio-demographic characteristics. The findings confirm Lieberson’s general conclusion that blacks lost ground, occupationally, to immigrants after 1920. However, they show further that: (1) northern- and southern-born blacks experienced different trends in relative occupational standing after 1920, (2) that these different trends were due largely to compositional differences between the two groups of northern blacks, especially educational differences, and (3) that blacks were generally less successful than immigrants at translating additional educational attainment into improved occupational status, with southern migrants experiencing the weakest occupational returns to education. It is concluded that compositional differences and a racially-defined occupational queue were the most important factors shaping group differences and trends in occupational standing between 1920 and 1970. Timing of arrival in the northern industrial economy and a response by whites to the “racial threat” from a growing black population were less important.     

Measures of occupational status in a special population

Previous research has shown that indirect measures of occupational status such as the Duncan Socioeconomic Index (SEI) are more valid than direct measures of occupational prestige, such as those developed by the National Opinion Research Center and by Treiman, for analyses of social mobility. The Professional, Technical, and Kindred (PTK) occupations available for the SEI are a biased sample of all PTK occupations. Do findings on the validity of the SEI pertaining to the general population hold for special populations, such as college graduates? Confirmatory factor analysis comparing the validities of four measures of occupational SES—the SEI, a 1960 counterpart of the SEI developed by Siegel and based on all Census occupations, the NORC prestige scale, and the Treiman international prestige scale—showed that the indirect measure developed by Siegel was clearly more valid than the other three measures. Since these findings indicate that the predictors in a regression equation are more valid than the criterion, there is some question as to what the criterion should really be.     

Assumptions of social mobility research in the U.S.: The case of occupational status

This paper examines the theoretical and empirical basis for common rank-orderings of occupational roles by raters throughout the world. From an illustrative comparison of occupational stratification in Australia and the United States we conclude tentatively that (1) commonalities in the socioeconomic characteristics of occupational roles provide the basis for interplace consistencies in “prestige” scores, (2) the structure of occupational mobility in the U.S. and Australia is largely similar, (3) this similar structure of occupational stratification manifests a common socioeconomic process which defines a (the?) major component of occupational mobility in capitalist, industrial (only?) societies. We infer that “prestige” scores for occupations are fallible estimates of the socioeconomic statuses of occupation, within the context of mobility processes in (at least) the U.S. and Australia.     

Using geographically weighted regression for environmental justice analysis: Cumulative cancer risks from air toxics in Florida

Previous quantitative research on environmental justice has been limited by simplistic assumptions used to measure health risks and traditional regression techniques that fail to discern spatial variations in statistical relationships. We address these gaps through a case study that examines: (a) whether potential health risks from exposure to hazardous air pollutants in Florida are related to race/ethnicity and socioeconomic status, and (b) how the significance of statistical associations between health risk and race/ethnicity or socioeconomic status vary across the state. This study integrates census tract level estimates of cumulative cancer risk compiled by the EPA with Census 2000 data and a spatial statistical technique known as geographically weighted regression that allows us to explore spatial variability in analytical results. Our findings indicate that while race and ethnicity are significantly related to cancer risks in Florida, conventional regression can hide important local variations in statistical relationships relevant to environmental justice analysis.     

Prestige versus socioeconomic status in the attainment processes of American men and women

This paper demonstrates the consequences to the researcher of choosing to analyze social mobility data with a prestige scale rather than with a socioeconomic index. First, the low intergenerational correlations reported for the International Prestige Scale are rejected when they are shown to be compatible with inadequate models of the processes of status inheritance. Second, the Duncan socioeconomic index is shown to be the preferred measure of status transmission in that it suffers from less random error than does the International Prestige Scale, particularly among men. Third, the occupational attainment processes of American men and women are described with socioeconomic scoring, and these findings are contrasted with those which obtain with prestige coding.     

Trends in exposure to industrial air toxins for different racial and socioeconomic groups: A spatial and temporal examination of environmental inequality in the U.S. from 1995 to 2004

In recent decades there have been dramatic declines in industrial air toxins. However, there has yet to be a national study investigating if the drop has mitigated the unequal exposure to industrial toxins by race and social class. This paper addresses this by developing a unique dataset of air pollution exposure estimates, by aggregating the annual fall-out location of 415 air toxins, from 17,604 facilities, for the years 1995 to 2004 up to census block groups (N = 216,159/year). These annual estimates of exposure were matched with census data to calculate trends in exposure for different racial and socioeconomic groups. Results show that exposure to air toxins has decreased for everyone, but African-Americans are consistently more exposed than Whites and Hispanics and socioeconomic status is not as protective for African-Americans. These results by race were further explored using spatially specified multilevel models which examine trends over time and across institutional boundaries.     

Evaluating Effectively Maintained Inequality: School and post-school transitions,socioeconomic background,academic ability and curricular placement

Effectively Maintained Inequality (EMI) is proposed as an explanation for contemporary socioeconomic inequalities in education. Socioeconomic inequalities are ‘maintained’ by students from lower socioeconomic backgrounds taking less advantageous curricula influencing their post-school destinations. The purpose of this study is to evaluate EMI by addressing several hypotheses derived from the EMI thesis using Australian longitudinal data. It analyses within-school transitions and the transition from school to post-school destinations (elite university, other university, vocational and no post-school study or training). The study also models curricular placement (subject choice). It finds that the transitions within- and post-school are more powerfully influenced by students’ academic ability than by socioeconomic background. Furthermore, subject choice has strong impacts on the transitions. Similarly, Year 12 subject choice is only weakly predicted by socioeconomic background, and more strongly influenced by ability and occupational interests. In turn, occupational interests are largely independent of socioeconomic background. The EMI thesis is not supported.     

The persistence of white flight in middle-class suburbia

Scholars have continued to debate the extent to which white flight remains racially motivated or, in contrast, the result of socioeconomic concerns that proxy locations of minority residence. Using 1990–2010 census data, this study contributes to this debate by re-examining white flight in a sample of both poor and middle-class suburban neighborhoods. Findings fail to provide evidence in support of the racial proxy hypothesis. To the contrary, for neighborhoods with a larger non-white presence, white flight is instead more likely in middle-class as opposed to poorer neighborhoods. These results not only confirm the continued salience of race for white flight, but also suggest that racial white flight may be motivated to an even greater extent in middle-class, suburban neighborhoods. Theoretically, these findings point to the decoupling of economic and racial residential integration, as white flight may persist for groups even despite higher levels of socioeconomic attainment.     

Household migration and the labor market position of married women

The present paper conceptualizes labor force participation among U.S. wives as both a determinant and consequence of household migration. A theoretical justification is provided for decomposing these relationships by occupational position of the wife. Applying log-linear models to data from the 1970 One-in-a-Thousand Public Use Sample, we corroborate previous research in that, on the average, the likelihood of interstate migration between 1965 and 1970 was greatest among families in which the wife was not employed prior to the move. However, among employed wives, those classified as professionals or managers were also found to accentuate the probability of household migration, particularly if the husband was not employed in 1965. The implication is that all types of employment by the wife need not limit family mobility as previous studies have suggested. Although migration was found to have a disrupting effect on the continuity of employment among most wives, this effect was most in evidence among wives employed in blue collar occupations. The data suggest the need for a careful reappraisal of traditional economic notions of migration, particularly as they apply to married women.     

Some cross-population comparisons of family bias in the effects of schooling on occupational status

It is a truism of research on social stratification that the effects of socioeconomic or family background on educational attainment and adult success lead to biases in the simple regressions of occupational status (or other putative outcomes of schooling) on educational attainment. The present analysis compares findings of family bias in the effects of schooling on occupational status across samples of siblings drawn from the Wisconsin Longitudinal Study and from Olneck's sample of brothers from Kalamazoo, Michigan. The comparative analysis shows that family bias in the effect of schooling on occupational status may be much less than is commonly believed and that very large samples may be needed to measure it reliably. Moreover, the analysis suggests that estimates of family bias are very sensitive to the specification of response variability in schooling. The analysis also illustrates some useful methods for cross-population comparison of structural equation models.

Components of change in the number of female family heads ages 15 to 44, an update and reanalysis: United States, 1940 to 1983

We review the literature dealing with the various components of change in the number of female family heads and conclude that P. Cutright's (1974, Journal of Marriage and the Family 36, 714–721) four components of change in the number of ever-married female family heads can be usefully applied to a reanalysis of decade-by-decade changes in this quantity among white and nonwhite women ages 15–44, from 1940 through 1980. However, we substantially revise and update Cutright's (1974) original data. Our findings include the fact that while the relative importance of the various components of increases in ever-married female family headship vary from decade to decade, overall trends are fairly similar for white and nonwhite women. Moreover, the rapid rise between 1970 and 1980 in the number of white and nonwhite female family heads among the never-married (single) continued through the 1980 to 1983 period. A decade ago, Cutright (1974) predicted that a change in the number of female family heads from 1970 on would reflect little more than changes in the numbers of ever- and never-married women ages 15–44. We discuss this inaccurate prediction and conclude that wishful thinking is a poor guide in forecasting the future.     

Occupational Gender Segregation and the Earnings Gap: Changes in the 1980s

The 1980 and 1990 U.S. Census data confirm the decline in the earnings gap between men and women. Occupational segregation by gender also declined during the 1980s. Cross-sectional decompositions show that 15% of the earnings gap would be eliminated if women′s occupation distributions were the same as men′s. Over-time decompositions show that declining occupational segregation accounted for about 36% of the decline in the earnings gap; most of the declining earnings gap resulted from more equal pay within occupations.

Selective Emigration, Cohort Quality, and Models of Immigrant Assimilation

In this article we identify sample underenumeration, changing cohort quality, and selective emigration as problems that threaten the validity of findings on immigrant socioeconomic assimilation derived from cross-sectional data. Using information on Mexican immigrants from the 1990 U.S. census and a unique binational source of data, we address the effects of these problems on cross-sectional regressions of English proficiency and wage attainment. Our results suggest that the underenumeration of temporary and undocumented migrants biases the estimated effects of human capital variables downward, but that selective emigration does not significantly affect cross-sectional models. We do find, however, that period of entry is a poor proxy for total migrant experience, and when we disentangle duration and cohort effects, we find some evidence for shifts in cohort quality over time, but not the systematic decline seen by others.
