The first indicator is the focus the others are compared with. Relationships are checked in levels (r) and in year-to-year changes (r_changes: the changes have their own linear trend removed; significance corrected for autocorrelation); lag is the shift at which changes line up best. UN errors: actual / projected − 1 for population, births and fertility, actual − projected for migration, life expectancy and mothers' age; IMF: actual − forecast. view_url opens the same view on the site."}
