Why country rankings change
Population values depend on censuses, civil registration, migration, births and deaths. Between official counts, values are projected. Rankings are useful, but they do not show density, income, age structure or living conditions by themselves.
How to use country values
Rounded numbers are often better for education and media than fake precision. They show scale without pretending that every birth, death and migration event is known instantly.
