Two African economies, one price basis.
Read South Africa and Nigeria’s GDP per capita on shared annual periods, without turning two national series into an African aggregate or a purchasing-power comparison.
Start with the original constant-price levels.
Only years with present values in both inputs enter this view. Gaps remain gaps; an absent observation is not zero.
Two national series, not a regional total
This comparison selects South Africa and Nigeria. It does not describe every reporting economy in the region, and it does not add the two observations into a regional measure.
The latest shared year is 2025: $5,713 for South Africa and $2,369 for Nigeria. Both values use constant 2015 US$ per person and the same reviewed indicator definition and methodology.
GDP per capita is economic output relative to population. It is not a household’s paycheck, a distribution of income, or a purchasing-power adjustment. Constant 2015 U.S. dollars provide a fixed price basis; they do not establish what a dollar buys in each reporting economy.
Make the comparison reproducible
The source contracts, exact reporting identities, original values, revision IDs and annual periods travel with this article’s input manifest. Open the workspace to change inputs or the year range. Its saved comparisons remain free.
Separate growth from the starting level.
Each series independently starts at 100 in 2000. Calculate: its value in a year ÷ its own value in 2000 × 100. A common index compares proportional change, while the original units and meanings remain different.
This index is eligible because the shared baseline is positive and the aligned quantity values are non-negative. It is not a causal result, a forecast, or a purchasing-power comparison.
