The report presents data on the demographic, social, and economic characteristics of persons 14 years of age and over who did hired farmwork during 1975, and summarizes the pertinent changes and trends in the size, composition, earnings, and employment patterns of the hired farm working force. Information is given on the Spanish-origin, white, black, and other hired farmworkers. Data were obtained through a survey conducted by the Census Bureau as a supplementary part of the December 1975 Current Population Survey. Tabular data are organized into four areas--historical data, the 1975 data, earnings by source of employment, and information on those employed solely in hired farmwork during the year and those employed in hired nonfarm work in addition to their farmwork. In 1975, there were about 2.6 million persons in the hired farm working force. The annual employment of farmworkers appeared to have stabilized after the long-term downward trend of prior years. Generally, hired farmworkers were young (median age 23 years), male (77%), and resided in nonfarm places (79%). Annual earnings averaged $2,552. About 72% were white, 11% were of Spanish origin, and 17% were blacks and others. Approximately 1.5 million worked only as farmworkers during the year; the remaining 1.1 million did both farm and nonfarm work. About 188,000 (7%) were migrant farmworkers. Annual earnings for these workers averaged $2,003, or $21.05 per day for 95 days of farmwork; 61% of all migrants did only farmwork during the year. (NQ)
