slightly less than half (48%
of all international migrants
� The percentage was
highest in Europe

Asia (57%)
Migration from South to North ?

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
