The missing women in STEM? Assessing gender differentials in the factors associated with transition to first jobs

Women remain underrepresented in the STEM workforce. We assess explanations for women's underrepresentation in STEM jobs, focusing on a cohort that came of age in the 1980s and 1990s, when women dramatically increased their representation in the scientific labor force. Data are from the NLSY79, and our analysis focuses on members of this cohort who received a college degree, with an emphasis on those who completed a degree in a STEM field. Our analyses test the extent to which college major, expectations to work in STEM, and family expectations shaped transitions into STEM occupations within two years of degree completion. Among those majoring in STEM fields there were no gender differences in transitioning into STEM jobs, though there were sizable differences in transitions to STEM employment by field of study. Of note are gender differences in associations between family expectations and transitions into STEM employment. The most career oriented women, who expected to marry late and limit fertility, were no more likely to enter STEM jobs than were women who anticipated marrying young and having two or more children. The men most likely to enter STEM occupations, in contrast, adhered to significantly more conventional gender ideologies than their female counterparts, expecting to marry at younger ages but also to remain childless. Results of our regression decomposition indicated that marriage and family expectations and gender ideology worked in opposite directions for men and women. Nonetheless, the majority of the gender disparity in transitions into STEM jobs was related to women's underrepresentation in engineering and computer science fields of study.     

College for some to college for all: Social background, occupational expectations, and educational expectations over time

The educational expectations of 10th-graders have dramatically increased from 1980 to 2002. Their rise is attributable in part to the changing educational composition of students’ parents and related to the educational profiles of their expected occupations. Students whose parents have gone to college are more likely to attend college themselves, and students expect occupations that are more prestigious in 2002 than in 1980. The educational requirements of particular occupation categories have risen only slightly. These analyses also reveal that educational expectations in recent cohorts are more loosely linked to social background and occupational plans than they were in 1980. The declining importance of parents’ background and the decoupling of educational and occupational plans, in addition to a strong and significant effect of cohort on educational expectations, suggest that the expectation of four-year college attainment is indeed becoming the norm.     

Military service and STEM employment: Do veterans have an advantage?

We use five years of American Community Survey data to examine how military service provides a non-degree-based pathway into STEM occupations. Military service is associated with STEM occupations in positive and surprising ways. Veterans are more likely than their civilian counterparts to work in STEM, an effect particularly strong for women and among workers without a STEM bachelor's degree. Among workers lacking STEM BAs, veterans were more likely to hold STEM occupations. Indeed, veterans lacking a college degree at all are more likely than their nonveteran counterparts to hold STEM employment. We conclude that military service in itself provides a rarely-discussed route to diversifying STEM and consider the policy implications.     

Gender differences in the impact of job mobility on earnings: The role of occupational segregation

In recent years, researchers have begun to explore the extent to which the impact of switching firms (inter-firm mobility) on wages varies between men and women. Using data from the NLSY79 from 1979 to 2012, this paper extends existing research by exploring how occupational segregation and individual level factors contribute to gender differences in the impact of voluntary inter-firm mobility on wages. The paper also examines how patterns vary depending on education level. Findings suggest that men without a college education receive greater wage gains from voluntary inter-firm mobility than similarly educated women although there is no overall gender difference for individuals with a bachelor's degree. The wage returns to voluntary inter-firm mobility for both men and women increase as a function of the male representation in the occupation. For individuals without a college education, the male premium to voluntary inter-firm mobility is largest in highly male dominated occupations. However, women with a bachelor's degree employed in highly male dominated occupations use voluntary inter-firm mobility to narrow the gender wage gap.     

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.     

The role of occupational attributes in gender earnings inequality, 1970–2010

Grounded in the research on the important role of social structures in forming gender inequalities, this study examines the effect of occupational attributes on the gender earnings gap over four decades. Using the IPUMS-USA from 1970 to 2010, the paper shows that occupational attributes cannot be reduced to the aggregate attributes of their individual incumbents. Rather, the effect of occupations on the gender earnings gap goes far beyond both the distributive role of occupational segregation and the effect of individual wage-related characteristics. Furthermore, occupations not only explain a significant portion of net gender pay gaps, but have also contributed to the narrowing of the gaps over the past several decades, as occupational attributes that favor women's pay have become more dominant over time.     

Gender composition of occupations and occupational characteristics: Explaining their true relationship by using longitudinal data

This paper analyzes the relationship between the gender composition of occupations and occupational characteristics that describe working arrangements and qualification requirements. While prior studies showed associations between the representation of females in occupations and these occupational characteristics, we are the first to explain their true relationship by applying an analytical research design. In this regard, we add three alternative relationship patterns to the widespread assumption that occupational characteristics affect the representation of females in occupations. First, it is possible that the relationship works in the opposite direction. Second, the relationship does not necessarily have to be causal but can just be a historical connection. Third, the representation of females in occupations may follow a self-enforcing cycle. To put the relationship between the gender composition of occupations and occupational characteristics to the test, we create a unique occupation panel dataset that aggregates individual data from the 1996 to 2012 waves of the German Microcensus. Our results confirm that occupational characteristics determine the representation of females in occupations. Moreover, we find some evidence that the representation of females follows a self-enforcing cycle.     

Educational indicators and occupational achievement

Many sociological and economic studies assume that the variable, Highest Grade Completed in School, is by itself an adequate measure of people's education for the purpose of explaining their occupational achievement. Use of Highest Grade Completed as the sole measure of education has at least two major shortcomings. It assumes people have (1) learned the same amount of (2) the same thing in an academic year. Supplementary education indicators are identified and tested to see if they have a substantial impact on occupational prestige or earnings. Background social statuses and Highest Grade Completed are controlled for in this test. Only measures of subject matter studied in high school or college have a statistically significant relationship with occupational achievement net of Highest Grade Completed and social background variables. Highest Grade Completed is quite adequate in measuring the impact of education on occupational achievement without help from the measures of subject matter studied.     

Not making the transition to college: School, work, and opportunities in the lives of American youth

Unlike traditional research on educational stratification that focuses on the pursuit of higher education, our study examines why young adults do not make the transition to college, using a nationally representative sample of college non-enrollees (N = 2640). In applying latent class analysis techniques, we identified multiple types of students who do not pursue college. One group of non-enrollees (27.6%) reports forgoing college because the economic barriers are too high - either because of college affordability or family financial responsibility. These youth had both low math test scores and low family income, and thus closely align with regression-based analyses on college enrollment that emphasize academic and economic constraints as the central barriers to educational progress. However, we also identified a second, often overlooked group of youth who had the academic preparation and family income support to enroll in higher education, but decided to forgo college because they preferred to work and to make money (18.3%). The heterogeneous motives of these youth suggest that postsecondary decisions are not always guided by academic and economic barriers, but sometimes driven by previous work experience and perceptions of local opportunities for school and work.     

Preferences,constraints, and the process of sex segregation in college majors: A choice analysis

The persistence of horizontal sex segregation in higher education continues to puzzle social scientists. To help resolve this puzzle, we analyze a sample of college entrants in Germany with a discrete choice design that allows for social learning from the experiences of others. We make at least two contributions to the state of research. First, we test whether essentialist gender stereotypes affect major selection mostly through internalization or rather as external constraints that high school graduates adapt their behavior to. Empirically, we find that internalized vocational interests better explain gendered major choices than conformance with friends' and parents' expectations does. Second, we scrutinize whether segregation results from women's anticipation of gendered family roles or from their anticipation of sex-based discrimination, but we find no evidence for either of these hypotheses. As in most previous studies, differences in mathematics achievement fail to explain gendered patterns of selection into college majors.     

Field of study variation throughout the college pipeline and its effect on the earnings gap: Differences between ethnic and immigrant groups in Israel

This study demonstrates the analytical leverage gained from considering the entire college pipeline—including the application, admission and graduation stages—in examining the economic position of various groups upon labor market entry. The findings, based on data from three elite universities in Israel, reveal that the process that shapes economic inequality between different ethnic and immigrant groups is not necessarily cumulative. Field of study stratification does not expand systematically from stage to stage and the position of groups on the field of study hierarchy at each stage is not entirely explained by academic preparation. Differential selection and attrition processes, as well as ambition and aspirations, also shape the position of ethnic groups in the earnings hierarchy and generate a non-cumulative pattern. These findings suggest that a cross-sectional assessment of field of study inequality at the graduation stage can generate misleading conclusions about group-based economic inequality among workers with a bachelor’s degree.     

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.     

Trends in gender segregation in the choice of science and engineering majors

Numerous theories have been put forward for the high and continuing levels of gender segregation in science, technology, engineering, and mathematics (STEM) fields, but research has not systematically examined the extent to which these theories for the gender gap are consistent with actual trends. Using both administrative data and four separate longitudinal studies sponsored by the U.S. Department of Education’s National Center for Education Statistics (NCES), we evaluate several prominent explanations for the persisting gender gap in STEM fields related to mathematics performance and background and general life goals, and find that none of them are empirically satisfactory. Instead, we suggest that the structure of majors and their linkages to professional training and careers may combine with gender differences in educational goals to influence the persisting gender gap in STEM fields. An analysis of gendered career aspirations, course-taking patterns, and pathways to medical and law school supports this explanation.     

Sex and marriage of raters in the evaluation of occupations

The evaluation of occupational prestige ratings obtained from different subgroups within the same society has been shown to be remarkably similar (Reiss, A. J., Jr., Duncan, O. D., Hah, P. K., and North, C. C., 1961, Occupations and Social Status, Free Press, New York; Svalastoga, K., 1959, Prestige, Class, and Mobility, Gyldendal, Copenhagen; Tiryakian, E. A., 1958, American Journal of Sociology 63 (January), 390–399). Our purpose is to explore how the gender and marital status of raters influence the evaluation of occupational prestige. Using more detailed data than heretofore available, we will reexamine the similarity between occupational prestige evaluations observed among female and male respondents. Models of the way in which characteristics of occupational incumbents, such as income and education, are constructed to explore possible differences in the ways in which male and female raters evaluate occupations. The results of this analysis by gender of rater will then be used to examine both the gender and marital status of raters.     

Scaling the prestige,authority, and income potential of college curricula

This paper develops the concept of “targeted education,” a theoretical ranking of college curricula, into a multidimensional framework. The new scales, based on the traditional stratification dimensions, prestige, authority, and income, are then used in a study of sex differences in the process of occupational achievement among men and women with college degrees. The targeted education scales predict occupational prestige and wages 7 years after the college degree, and they point out interesting differences between male and female attainment processes. In general, targeted education has a greater quantitative impact for men's occupational outcomes than for women's prestige and income, but results also suggest significant qualitative differences between men and women. A large proportion of women target their education toward, and end up in, an under-employed labor pool for the primary and secondary school system.     

Staying in STEM or changing course: Do natives and immigrants pursue the path of least resistance?

This paper examines why Science, Technology, Engineering and Math (STEM) fields are becoming “immigrant” fields of study as native students shift from STEM fields to law, medicine and business. Using data from the 2010 National Survey of College Graduates, the analyses find that foreign college-educated immigrants with STEM degrees tend to remain in STEM fields, while natives are more likely to shift from STEM fields to law, medicine and business in graduate school. Among those who moved into law, medicine and business, the gains in earnings are larger for natives than for foreign educated immigrants. These results have important implications for the social mobility of highly educated natives and immigrants.     

Gender and migration on the labour market: Additive or interacting disadvantages in Germany?

Despite substantial differences in labour market attainment according to gender and migration status, gender and ethnic differences in labour market behaviour are most often studied separately. In contrast, this study describes and analyses interactions between gender, ethnic background and immigrant generation with regard to labour market participation, part-time work, and occupational status. The double comparison aims to reveal whether gender gaps in these labour market outcomes among the majority population generalise to ethnic minorities. Moreover, we ask whether variation in gender gaps in labour market behaviour follows the patterns in migrants’ origin countries, and whether gender gaps show signs of intergenerational assimilation. Our heterogeneous choice and OLS regressions of 2009 German Microcensus data reveal considerable variation in gender gaps in labour market behaviour between East and West Germany, across ethnic groups and across generations. Intergenerational comparisons show that most ethnic minorities assimilate towards German patterns of gendered labour market attainment.     

The science identity and entering a science occupation

The initiative to increase the number of students in STEM disciplines and train them for a science-related job is a current national focus. Using longitudinal panel data from a national study that followed underrepresented college students in STEM fields, we investigate the neglected role that social psychological processes play in influencing science activity among the young. We study the impact of identity processes related to being a science student on entering a science occupation. More broadly, we examine whether an identity formulated in one institutional setting (education) has effects that persist to another institutional setting (the economy). We find that the science identity positively impacts the likelihood of entering a science occupation. It also serves as a mediator for other factors that are related to educational success. This provides insight into how an identity can guide behavior to move persons into structural positions across institutional domains.
