PIP: This article presents vital statistics on the Black population in South Africa. It is pointed out that apartheid interfered with data collection and quality, demographic dynamics, and population activities and research. The percentage of Black population increased from 68.6% to 76% during 1946-90. The percentage of White population declined from 20% to 13%. Colored and Indian populations remained stable. The annual rates of natural increase during 1985-90 were 0.6% for Whites, 1.7% for Indians, 1.8% for Coloreds, and 2.8% for Blacks. Blacks had the largest proportion aged under 15 years. Whites had the largest proportion of elderly. Infant mortality was estimated by the World Health Organization in 1980 to be 12/1000 for Whites and 120/1000 for Blacks. Infant mortality was an estimated 34/1000 for Blacks in Durban, compared to 197/1000 for Blacks in rural Kimberley. By the end of the 1980s, Blacks still had the highest infant mortality rates of 86/1000. Fertility declined for Whites and Indians to below replacement levels by the end of the 1980s, declined from 6.4 to 3.2 for Coloreds during 1950-85, and declined by 1.8 births during 1950-89 among Blacks. Contraceptive prevalence was about 64% among Blacks and 92% among Whites in 1989-90. Blacks preferred injectables. Whites preferred sterilization. In 1988, migration out of South Africa was highest for Blacks and Coloreds. There were more White and Indian immigrants. Blacks were the least urbanized, least educated, and lowest in income resources.
