A decline in total fertility rates, alongside strategic human capital development, offers a powerful pathway for economic transformation. In Zambia, approximately 43% of the population is currently under the age of 15, compared to 48% at the turn of the century. The core working-age cohort (ages 15 to 64) now accounts for 54% of the population and represents the fastest-expanding segment of the workforce, while senior citizens aged 65 and over make up just 3%. The national fertility rate has fallen from a high of 6.7 births per woman in 1990 to 4.4 in 2020, with projections indicating a further decline to 2.6 by 2050.
While enrollment in basic education has expanded significantly, with primary school net enrollment reaching 89%, deep-seated structural bottlenecks remain. In many remote rural provinces, secondary school progression rates drop below 38%, which severely limits the skills base available to high-value industries.
Despite shrinking average family sizes, Zambia’s overall population continues to grow at over 2.8% annually. This sustained expansion is driven by two main elements. First, the historical legacy of high fertility rates means there is a very large generation of young women currently entering their prime reproductive years—a phenomenon known as demographic momentum. Second, public health initiatives and improved disease control have boosted survival rates: under-five mortality has fallen dramatically, and overall life expectancy has risen from 48 years in 2000 to nearly 64 years today, with projections pointing to 73 years by 2050.
Concurrently, Zambia is experiencing rapid spatial redistribution, with 44% of its citizens currently residing in urban centers. This urban share is projected to grow to 53% by 2035. Historically, no country has achieved upper-middle-income status without a substantial shift away from rural subsistence agriculture. Urban agglomerations support economic growth through two channels: they concentrate diverse talent pools that stimulate informal and formal service-sector enterprise, and they reduce the per-capita cost of basic infrastructure, from power grids to high-speed telecommunications.
If matched with robust job creation, Zambia's evolving demographic profile could yield a substantial demographic dividend, strengthening domestic aggregate demand and driving structural diversification.
