Abstract
ZERO POPULATION GROWTH (Z. P. G.): Implementation of a goal: World population growth which currently takes place at exponential rates must, proceeding from the present base of about four billion and with a doubling time of approximately thirty years, inevitably lead to a very early over-filling of the finite planet earth, man's only home for the forseeable future. Hence Z.P.G. is the only logical ultimate goal of the world's human population. The demographic conditions at present prevailing in the Republic of South Africa point to a very rapid acceleration, in the immediate future, of the natural growth rates of especially the Black and Coloured Sections of the Community. This could result in huge population increases especially during the next century. The following tables summarise the salient data:{fx35-1} Utilising the data of Tables I and II, estimations of possible future growth are made and summarised in Table III {fx36-1} X Black birth rates approximately 43 per 1 000 per year over period 1970/75; a drop of 2,5% every five years to 1990/1995 and then of 5% every five years until Z.P.G. is reached after about three centuries. O Black Birth Rates approximately 43 per 1 000 per year over period 1970/75; a drop of 9,4% every five years to 1990/1995 and then 18,8% every five years until Z.P.G. is reached of er about one century. Drop in death rates somewhat higher in case of rapid reduction in fertility. COMMENT. The fourteen fold increase of the present population to some 350 millions, resulting from the gradual decline of present fertility is totally and utterly unacceptable, as such a vast number of humans could never be accommodated in the R.S.A. The suggested rapid reduction of fertility leading to a stable population of some 65 millions after about one century is not only highly desirable but also feasible. The actual rate of reduction would in fact be somewhat slower than that which has already been achieved during the last two to three decades in such countries as Taiwan, Malasia, South Korea, Hong Kong and Singapore. Every effort should therefore be made to achieve such a rapid reduction in the growth rates of all the peoples of this country by a multiple increase in present family planning efforts.
