The Hard Facts

Cape Town added over 2 million residents in two decades. Internal migration from the Eastern Cape is the primary driver, with roughly 125,000 new arrivals per year. The city crossed 4.5 million at the 2022 Census and will pass 5 million before the next one.

Cape Town skews younger than the national average. Nearly a quarter of residents are children under 15. The working-age bulge (25 to 49) drives housing demand and commuter traffic. The over-65 cohort is small by European standards, which shapes healthcare and social spending priorities.

Afrikaans, isiXhosa, and English each claim roughly a third of the population. The split maps onto geography: Afrikaans dominates the Cape Flats and Northern Suburbs, isiXhosa in the south-east townships, English along the Atlantic Seaboard and City Bowl. Most residents code-switch across two or three languages in a single conversation.

Cape Town's metro area covers 2,461 km\u00b2. That is 56% larger than Greater London, but with less than half the population. The sprawl is not an accident: apartheid-era forced removals pushed communities to the periphery, and post-1994 housing has largely continued the pattern. The result is long commutes, expensive infrastructure, and a city that is hard to serve with public transport.
