The document reports findings from the latest survey of multiple jobholders 16 years old and over. About 3.9 million workers held two or more jobs in May 1975. This accounted for 4.7 percent of all employed persons. The multiple jobholding rate for men was 5.8 percent and 2.9 percent for women. The rate was also higher for whites than blacks. The proportion of multiple jobholders who are women increased from 16 percent in 1970 to 24 percent in 1975. About 23 percent (900,000) of all moonlighters had at least one job in agriculture. The multiple jobholding rate for workers whose primary jobs were in agriculture (7 percent) continued to be higher than for those in nonagricultural industries (4.6 percent). Men whose primary jobs were as teachers below the college level had the highest moonlighting rate (16 percent). By industry, men whose main jobs were in public administration in state and local governments, and in educational services had the highest rates (12 percent). The proportion of multiple jobholders holding second jobs to meet regular expenses (35 percent) was slightly higher than a year earlier (32 percent). The next higher proportion of multiple jobholders moonlighted mainly because they enjoyed the work (18 percent). Five tables support the data analysis. (Author/EC)
