International migrants are defined as persons outside their country of birth for at least a year. Each migration corridor has unique features, but there are four major migration flows, often summarized as S-S, S-N, N-N, and N-S, where South is a developing country and North is an industrialized country. This Population Bulletin explains why people cross national borders, the effects of international migration on sending and receiving countries, and the struggle to improve migration management.
