The data and methods are provided for generating a labor life table for China in 1988. The purpose is to supply a useful instrument for studying, planning, and analyzing employment and social services, welfare programs, and insurance. These tables were constructed using age- and sex-specific employment data from the 1% sample of demographic data for 1987 in 13 nonfarming sectors. Employment was derived from the 1985 Industrial Survey on 2 sectors of the nonfarming population. Urban employment and rural agricultural employment were not calculated because of the imprecision of the data. The age structure has unique characteristic differences between the employment rate curves of the material and nonmaterial production sectors. The peak for the nonmaterial production sector is near 50 years for men and 44 years for women, while the curve for the material sector is more nearly bell-shaped with a peak for females at 20-30 years. The female employment pattern indicates that women continue working after the birth of a child, and women do not return to the work force once they resign. The reasons for the pattern in nonmaterial production are indicated. The method used to calculate the labor life table employs the same methods as the multiple life table approach for mortality, with some modifications. The assumption is a static labor population between the ages of 15-70 years. The age for which employment is the highest is selected; then the number of people employed is generated. Employment beyond the peak age is derived through the % of the labor force in the total population. The arithmetic mean value of the labor force for adjacent age groups is determined by survivors until a particular age. Mean work expectancy years and age-specific cumulative labor force are calculated per the life table method. As data become available, causes of death of the labor force and transfer of labor between sectors and regions may be computed. An example of retirement information is that 60-year old workers receive their pensions for an average number of years following retirement of 17.8-3.33 give or take 14 years. The data provided in this article are also available from the 1990 Yearbook of the Chinese Populations.
