The Demographic Dividend

This research paper by the Institute for Security Studies explains the concept of the demographic dividend, focusing on the first dividend where the working-age population grows relative to dependants. It details the metrics used to identify this window of opportunity and compares the timing, peak ratios, and durations of this dividend across various global economies, with a specific focus on Africa and Nigeria.

• The first demographic dividend occurs when the proportion of working-age people (aged 15 to 64) increases relative to dependants, which includes children under 15 and adults 65 and older. This shift can accelerate income growth because the labour force grows faster than the dependent population, although this growth is not automatic and requires supporting policies in governance, job creation, education, and health.
• Several metrics are used to identify the first demographic dividend: a working-age to dependant ratio of 1.7:1 (or a working-age population exceeding 62% of the total), a total fertility rate between 2.8 and 2.1 children per woman, a dependency ratio below 0.6, or a median age between 25.5 and 41 years.
• The timing of the demographic window varies by income level: high-income countries entered on average in 1966, upper-middle-income in 2000, and lower-middle-income in 2016, while low-income countries are expected to enter in 2054. The peak ratio and duration of this window significantly impact long-term prosperity; for example, China and the Asian Tiger economies achieved much higher peaks (2.7:1 and 2.8:1) than their peer groups.
• Nigeria is projected to have the third-largest population globally by around 2044, surpassing the US. However, under the Current Path, Nigeria is not expected to reach a 1.7:1 ratio until approximately 2058, peaking at 2:1 around 2092, which suggests moderate income growth occurring much later than in other countries.
