Table 7 Summary statistics for bilateral migration flows over five-year periods between 1990 and 2015 based on six flow estimation methods. All numbers except the Proportion Zero are in units of individuals per five years. N is the number of migration corridors modelled: 200 countries of origin × 200 countries of destination × 5 quinquennial intervals.

From: Bilateral international migration flow estimates for 200 countries
