各指標的意思

Total population
Number of people living in the country at mid-year, regardless of citizenship.
Total fertility rate
Births a woman would have over her lifetime at current rates. About 2.1 keeps a population steady.
Life expectancy at birth
Years a newborn would live if current mortality patterns stayed the same.
Population aged 65 and over
Share of the population aged 65 and over — the standard measure of population ageing.
Crude death rate
Annual deaths per 1,000 people. It rises with an older age structure, so it is not a measure of health on its own.
