ABSTRACT

This paper compares and contrasts household structure indicators for six of the main U.S. race/ethnic groups at two geographical levels: at the national level and in custom-tailored local areas surrounding research sites where small-scale qualitative studies of complex households for each race/ethnic group were done. Four research questions are explored. To what extent do measures of household structure and complexity in the overall U.S. population reflect similar patterns for different race/ethnic groups, or mask variations among those populations? How do local measures of household structure and complexity add to our understanding of population and household trends? What factors interact with and influence household structure patterns? What are the implications of these findings for the perennial goal of improving census coverage across race/ethnic groups in future censuses?

Nine household structure indicators are explored at local and national levels for six race/ethnic groups: African Americans (coastal Virginia); non-Hispanic whites (upstate New York), Hispanic immigrants (Central Virginia), Korean immigrants (Queens, New York), Navajos (northern Arizona), and Eskimos (northern Alaska). For the latter groups, national statistics are presented for Asians, American Indians, and Alaska Natives, respectively. Data come from Census 2000 tables in the American FactFinder system at www.census.gov. The decennial census is the only dataset large enough to permit reliable statistics on very small race/ethnic subpopulations at local geographical levels, allowing these finegrained comparisons to be done.

Selected findings include the following. Measures of household structure and complexity in the overall U.S. population do not reflect similar patterns for different race/ethnic groups; they mask notable variations among the subpopulations and geographical levels. This is because non-Hispanic white households differ markedly from those of the other groups, with the lowest proportions of households in eight of the nine household structure indicators. Yet, as the largest group comprising 75% of all U.S. households, they heavily influence (and skew downward) statistics on the overall national household structure indicators examined here. Non-Hispanic whites also have one of the lowest growth rates, with the result that as the proportion of these households declines over coming decades, their influence on overall household structure statistics is likely to wane. If trends remain constant, household structure and complexity indicator rates are likely to rise to reflect patterns of the minority subpopulations.

The census coverage tie-in is that race/ethnic minorities, complex households, and nonrelatives are all subpopulations that have been associated in past research with census coverage errors: as they increase over time, coverage errors may increase in tandem. These findings suggest that further ongoing research and monitoring of changing household structure trends by race/ethnicity and geographical levels may suggest adjustments that might be made to enumeration methods and operations to improve census coverage.
