About this indicator
Total population refers to all residents of a country or territory, regardless of legal status or citizenship. It reflects demographic dynamics driven by births, deaths, and migration.
Population data are essential for calculating per capita indicators and for understanding the scale of an economy, its labor force, and its social services demand. Changes in population size have direct implications for economic growth potential, fiscal sustainability, and resource allocation.
This indicator is measured at mid-year (July 1) and expressed in number of people.
