This report based on the March 1985 supplement to the Current Population Survey presents demographic, social, and economic data on the Hispanic population in the United States, and focuses on social and economic changes between 1982 and 1985. The Hispanic civilian noninstitutional population in March 1985 totaled about 17 million, a 17% increase since 1980; the non-Hispanic population increased 4% in that period. Between 1982 and 1985: (1) the median age of Hispanics rose from 23.9 to 25.0 years; (2) the proportion of Hispanics 25 and over with at least a high school diploma increased from 45% to 48%; (3) the proportion of married couple families fell from 74% to 72%; (4) the unemployment rate for Hispanics 16 and over fell from 13.4% to 11.3%; and (5) there was no change in the real median income of Hispanics, while that of non-Hispanics rose 3.5%. The origins of Hispanic Americans were about 61% Mexican, 15% Puerto Rican, 6% Cuban, and 10% Central or South American. These subgroups varied considerably in educational attainment, family size, family composition, employment, and median family income. The report includes 3 graphs and 27 detailed tables of data on demographic, social, and economic characteristics. Appendices cover the methodology for development of independent post-census estimates (component estimation technique), summary tables of selected characteristics for the years 1982 to 1985, definitions, and data source and reliability.
