International migration flows

Migration flows data capture the number of migrants entering and leaving (inflow and outflow) a country over the course of a specific period, such as one year (UN SD, 2017). Data on migration flows are essential for understanding global migration patterns and how different factors and policies in countries of origin and destination may be related to flows. However, in contrast to migration stocks data, estimates on migration inflows and outflows by country of origin and destination are not available at the global level. Currently, only 45 countries report migration flow data to the United Nations (UN DESA, 2015).

Migration flows data on migrants entering and leaving over the course of a given time period (usually a calendar year) are often confused with migration stock data which estimate all migrants residing in a country at a particular point in time (UN SD, 2017, emphasis added).
