Population projections, 1980-2000 and long-term (stationary population)

Population projections -- 1980-2000 and long-term (stationary population) are presented in tables for Africa the United States and Canada Latin America Asia Europe and Oceania. The base year for the projection of base total population and age/sex composition is 1980. The total population in was taken from a variety of sources but the principal source was the United Nations Population Division -- World Population Trends and Prospects by Country 1950-2025: Summary Report of the Assessment 1980 a computer printout. The base year mortality levels used in the projection of mortality level and trend are in general the same as those used in the recent United Nations projections. The principal source of the base fertility rates was also the revised United Nations population projections. Throughout the projections it was assumed that international migration would have no appreciable impact. Population projection was prepared separately for every country in the world. Since many countries reached stability only after 175 years of projection the results of the projection are presented at 5-year intervals for the 1980-2000 period and at 25 year intervals thereafter. For each of the 165 separate units the following information is presented in the accompanying tables: population by sex and 5-year age groups; birth rate death rate and rate of natural increase; gross reproduction rate total fertility rate; expectation of life at birth and infant mortality rates for males and females separately; and net reproduction rates. According to this projection the total world population would increase from 4.416 billion in to 6.114 billion in the year 2000. The average growth rate during 1980-2000 would be about 1.63% per year decreasing from 1.71% in to 1.42% in the year 2000. The birth rate would decline by 5 points and the death rate by 2 points. The share of the population in less developed regions would be 1.94% per year compared to 0.59% per year for more developed regions. The estimated hypothetical stationary population of the world according to the present projection is 10.1 billion.
