The Special Labor Force Report shows a substantial rise in the labor force participation rates of married women and single and divorced persons. Also explored is the downward trend of married men (55 years old or over) as members of the labor force. This decline was due mainly to early retirements and to some extent to a rising incidence of reported disability. The report notes a rise in the labor force participation of multiple worker families but not of women heads of households. These findings were compiled from the annual nationwide survey of marital and family characteristics of workers in the population 16 years old and over. Appended to the report are statistical tables and charts. (BP)
