What Drives Racial Segregation? New Evidence Using Census Microdata
October 2002
Working Paper Number:
CES-02-26
Residential segregation on the basis of race is widespread and has important welfare consequences. This paper sheds new light on the forces that drive observed segregation patterns. Making use of restricted micro-Census data from the San Francisco Bay Area and a new measurement framework, it assesses the extent to which the correlation of race with other household characteristics, such as income, education and immigration status, can explain a significant portion of observed racial segregation. In contrast to the findings of the previous literature, which has been hampered by serious data limitations, our analysis indicates that individual household characteristics can explain a considerable fraction of segregation by race. Taken together, we find that the correlation of race with other household attributes can explain almost 95 percent of segregation for Hispanic households, over 50 percent for Asian households, and approximately 30 percent for White and Black households. Our analysis also indicates that different factors drive the segregation of different races. Language explains a substantial proportion - more than 30 percent - of Asian and Hispanic segregation, education explains a further 20 percent of Hispanic segregation, while income is the most important non-race household characteristic for Black households, explaining around 10 percent of Black segregation.

The Relationship of Personal and Neighborhood Characteristics to Immigrant Fertility
August 2002
Working Paper Number:
CES-02-20
We find that fertility varies by immigrant generation, with significant declines between the first and subsequent generations for groups with large immigrant population. However, we find that personal characteristics--such as educational attainment, marital status, and income levels--are much more important than immigrant generation in understanding fertility outcomes. In fact, generations are not independently important once these personal characteristics are controlled for. We maintain that declining fertility levels among the descendants of Mexican and Central American immigrants are primarily the result of higher educational attainment levels, lower rates of marriage, and lower poverty. For example, a four-year increase in educational attainment decreases children ever born (CEB) by half a child. We conclude that immigrant generation serves as a proxy for changes in other personal characteristics that decrease fertility. Neighborhood characteristics have some bearing on fertility, but the correlations are relatively weak. Among Mexican and Central American immigrants and their descendants, the most consistent predictor of children ever born (CEB) at the neighborhood level is the percentage of Hispanic adults. However, no neighborhood characteristics bear any statistical relationship to current fertility, the measure that emphasizes recent births. This pattern of evidence suggests that the observed relationships between neighborhood characteristics and fertility are based on selection into the neighborhood rather than on neighborhood influences as such.

Exiting Self-Employment: An Analysis of Asian Immigrant-Owned Small Businesses
November 1998
Working Paper Number:
CES-98-13
Part of the uniqueness of the immigrant Asian business community in the U.S. lies in the fact that many among the highly educated pursue self-employment in small-scale, low-yielding retail and personal service fields. This study analyzes owner departure for a nationwide sample of small businesses owned by Asian Indian and Filipino immigrants and a comparison group of Asian nonimmigrant firm owners. Controlling for firm and owner traits, highly educated Asian immigrant owners are more likely than others to exit self-employment over the 1987-1991 period; exit from traditional fields (retail and personal services) is pronounced. These exit patterns do not typify the comparison group. Findings are consistent with the hypothesis that self-employment is often a form of underemployment among Asian immigrants.

Immigrant Status, Race, and Institutional Choice in Higher Education
March 1998
Working Paper Number:
CES-98-04
This paper examines the postsecondary enrollment decisions of immigrant students, expanding on previous work by explicitly considering their choices among institution types and by examining differences across generations and racial/ethnic categories. Using data from the National Educational Longitudinal Study (NELS:88), we hypothesize that community colleges may play a more significant role in providing access to higher education for immigrants than for the native-born population. Our results support our hypothesis only among Asian immigrants. First-generation black immigrants have a higher probability of enrolling in private vocational schools, while second-generation Hispanics (and native blacks) have a higher probability of enrolling in both public and private four-year colleges and universities.

Interfirm Segregation and the Black/White Wage Gap
August 1996
Working Paper Number:
CES-96-06
This paper studies interfirm racial segregation in two newly developed firm-level databases. Within the representative MSA, we find that the interfirm distribution of black and white workers is close to what would be implied by the random assignment of workers to firms. However, we also find that black workers are systematically clustered in "black" employers where managers, owners, and customers are also black. These facts may be reconciled by the facts that a) there are not enough black employers to generate much segregation and that b) perhaps other difficult-to-identify forces serve to systematically integrate black and white workers. Finally, we find that the black/white wage gap is entirely a within-firm phenomenon, as blacks do not work in firms that pay low wages on average.

Determinants Of Survival And Profiability Among Asian Immigrant-Owned Small Businesses
August 1993
Working Paper Number:
CES-93-11
The immigrant entrepreneur is often seen as a member of supportive peer and community subgroups. These networks assist in the creation and successful operation of firms by providing social resources in the form of customers, loyal employees and financing. This study provides evidence that the success and survival patterns of Asian immigrant firms derive from their large investments of financial capital and the impressive educational credentials of the business owners. Heavy utilization of social support networks typifies the less profitable, more failure-prone small businesses owned by Asian immigrants.

Self-Employment Trends Among Mexican Americans
August 1990
Working Paper Number:
CES-90-09
Minority businesses are commonly aggregated into groups of 1) black, 2) Hispanic, and 3) Asian-owned firms. These analytical groupings may, in fact, be useful if blacks, Hispanics and Asians exhibit intra-group similarities and intergroup differences in terms of business development patterns. The applicable similarities and differences do appear to typify the Asian and black groups of self-employed, but they do not typify Hispanic-owned small businesses. In other words, "Hispanic" does not appear to be a useful category for analysis. The Hispanic subset, Mexican American-owned firms, is judged to be suitable for analysis. Most minority-owned firms have traditionally been started with minimal financial capital inputs by owners who have not attended college. The resultant small scale firms have frequently oriented their operations toward serving a low income minority clientele. In this study, I investigate two closely interrelated broad hypotheses on minority business dynamics, utilizing a sample of Mexican American business establishments drawn from the Characteristics of Business Owners data base: Traditional firms - these firms tend to a) be small scale, b) have high failure rates, c) and generate few jobs because of their minimal owner inputs of financial and human capital. Emerging firms, in contrast, are most commonly started by better educated owners--many of whom have attended four or more years of college--and financial capital inputs are high relative to those observed in traditional lines of business. It is because of these larger financial and human capital inputs that emerging firms tend to be a) larger scale, b) have lower failure rates, and c) generate more jobs, relative to their traditional cohorts. Sociologists have used the term "protected market" to describe the culturally-based tastes of ethnic minorities that can only be served by co-ethnic businesses. Particularly in the early years of settlement, immigrants are assumed to patronize co-ethnic enterprises, and this pattern of patronage seems to typify Hispanic enclaves in areas such as Southern California. Whether or not the resultant protected market is an asset to Mexican American firms-- particularly those in traditional fields such as small-scale retailing--is investigated econometrically. The evidence indicates that the protected market provided by immigrants patronizing co-ethnic enterprises is an absolute hindrance to Mexican American business viability. The very low incomes of most recent immigrants constrain the attractiveness of this protected market. The state of the barrio business community reflects the economic circumstances of its clientele.

The Characteristics of Business Owners (CBO) Database
October 1989
Working Paper Number:
CES-89-09
The Bureau of the Census conducted the Characteristics of Business Owners (CBO) survey for the Small Business Administration and the Minority Business Development Agency in 1986. The CBO collected information from a national sample of 126,000 business owners, surveying the demographic and economic characteristics of owners and the economic performance of their firms. A major feature of the CBO is the large numbers of Hispanic, Asian and Other, Black and Women businesses, in addition to nonminority, male-owned businesses. The CBO data series also serves the broader purpose of providing data on characteristics of owners and firms in the small business population. This paper provides a report of the purpose, content, and basic procedures used for the survey and presents a preliminary discussion of the coverage and overall response.
