Migration from South to North ?

Source: Trends in International Migrant Stock: The 2015 Revision

International migrant stock, 2015 (in millions)

South to South migration has overtaken South to North Migration

� Population censuses allow to produce highly comparable global indicator on international migration (migrant stock)

� Significantly untapped potential for analysis when properly disaggregated (age, sex, country of birth/citizenship, level of education, occupation etc.)

� Scope for data exchange by country of birth/citizenship (diaspora profiles)

� Ensure data availability from 2020 round of population and housing censuses
