[A preliminary analysis of negative population growth in Taicang County].
摘要
This report attempts to analyze the negative population growth and its significance in Tai-Cang County, China. Based on population data provided by local Tai-Cang authorities, family planning effectively lowered the birth rate from 11.9% between 1960-1969 to 3.0% between 1979-1983. The rate of single-child families grew enormously while the number of 2-child families reached a record low. Families with more than 2 children virtually vanished by 1983. Moreover, while a younger marriage age in 1981 and 1982 contributed to a slight increase in the birth rate, new marriage laws in 1983 caused an older marriage age and acted to lower the birth rate due to the fact that mothers were bearing children at an older age. A change in population components also influenced this low birth rate: the county population below the age of 14 is 21.2% compared with 33.6% nationally; however, the percentage of the population in this county over the age of 65 is 8.5% while the national figure is 4.9%. Finally, the marriagable population of females (i.e., 23 years old) was slightly lower between 1982-1984 due to the low birth rate seen from 1959-1961. The findings indicate that family planning is effective in lowering birth rates along with late marriages and older childbearing ages. The negative population growth in Tai-Cang County, however, is a temporary phenomenon. The indications are that the problems and shortcomings of family planning must be overcome, regional population planning must be improved, and the study of eugenics and optimum population reinforced. The report also notes that the population trend is toward aging.
