The detailed results of the computation for Projection A and Projection B are presented in Tables 1 to 6. The figures for Projection A given in Table 1 show that if fertility measured by the gross reproduction rate increases from 0.841 in 1980 to 0.939 in 1985 and then to 1.025 in 1990 and thereafter, the population of Singapore is expected to increase from 2,413,945 in 1980 to 3,087,303 in 2000 and to 3,499,822 in 2020. It continues to increase to 3,599,540 in 2035, and after this it declines to 3,582,173 in 2050. Thereafter it increases again but very slowly, reaching 3,604,089 in 2070. In fact, in broad terms the population is seen to remain constant at about 3.6 million from 2025 onwards.

The figures for Projection B given in Table 4 reveal that a completely different path would be followed by the population in the future if the gross reproduction rate remains constant at the 1980 level of 0.841. In this case the population is expected to grow from 2,413,945 in 1980 to 2,945,060 in 2000 and to the peak of 3,129,313 in 2020, after which it follows a downward trend all the way. From the peak of 3,129,313, the population will decline to 2,990,138 in 2035, to 2,703,184 in 2050, and finally to 2,361,677 at the end of the period in 2070.
