This paper presents the detailed results of the computation of the population projections for Singapore by sex and for time intervals of five years from 1980 to 2070. Two sets of figures were prepared to indicate two plausible future courses of population trends, one according to replacement fertility from 1990 thereafter and the other according to constant 1980 fertility. They are known as Projection A and Projection B, respectively. A brief description of the methodology adopted to prepare these population projections and a short commentary on the results of the computation are also presented.
