INTRODUCTION

Table showing characteristics of Singapore's demographic phases from Phase 1 (1940s–1960s) to Phase 4 (Current).
A graph showing Singapore's population and growth from 1950 to 2009 with resident and foreign population data.

FERTILITY DECLINE REGARDLESS OF POLICY

A FOURTH PHASE: NET MIGRATION TAKING OVER NATURAL INCREASE AS THE MAIN SOURCE OF POPULATION GROWTH

Addressing Lowest Low Fertility

Immigration

Social and Age Structural Shift

Line graph shows population age structures for 1990, 2009, and 2030; higher population seen in age 20-39 and 50-69.

RAISING FERTILITY IS THE MORE SUSTAINABLE SOLUTION

THREE PHASES OF DEMOGRAPHIC DEVELOPMENT

Phase I: High Fertility, Low Mortality, No Population Policy

Phase II: Low Fertility, Low Mortality, Anti-Natalist Population Policy

FIGURE 1. CRUDE BIRTH RATE AND CRUDE DEATH RATE, 1950–2008

Graph showing a declining trend in CBR and CDR from 1950 to 2006, with CBR consistently higher than CDR.

FIGURE 2. TOTAL FERTILITY RATE AND IDEAL FAMILY SIZE

Graph showing a decline in total fertility rate from 1957 to 2007, while the ideal family size remains relatively stable.

Phase III: Continued Low Fertility, Low Mortality but High Migration, Pro-Natalist Population Policy
