What the columns mean

Working figures are rounded values for around 2023 to 2024, drawn from UN, World Bank and national census style sources and simplified for classroom use. Rates per 1,000 are shown as whole population rates. Natural increase, growth rate, density, dependency ratio and doubling time are calculated from the columns beside them, so the numbers always agree with each other. Treat the table as your one source of truth for this task.
