This report presents data on the demographic, social, and economic characteristics of the U.S. Hispanic population. The Bureau of the Census collected this information in the March 1989 supplement to the Current Population Survey. Data on Hispanic households includes household composition, urban and rural residence, tenure, availability of telephone, and income. Data on Hispanic families includes composition, size, income, and poverty. The Hispanic population, totalling 20.1 million in 1989, continued to grow at a rapid pace. Hispanic households were more likely to live in urban areas than non-Hispanic households and less likely to live in homes they owned or that were purchasing in 1989. Hispanic families tended to be larger, were less likely to have a phone, and were more likely to be poor than non-Hispanics. Only 60% of young Hispanic adults reported they had completed 4 years of high school or more, compared with 89% of their non-Hispanic counterparts. The report contains tables that break down the population by age, sex, marital status, and educational attainment, and that estimate population figures for various Hispanic ethnic groups (Mexican, Puerto Rican, Cuban, etc.). Other tables give information on Hispanic employment, household size, and income levels. Appendices in the report offer definitions of terms, describe changes in census processing procedures and research on data fluctuations, and provide information on the source and accuracy of data estimates.
