Researchers have unveiled a new statistical method for estimating migration flows between countries, using the so-called pseudo-Bayes approach.<\/p>\n
They show that rates of migration\u2014defined as an international move followed by a stay of at least one year\u2014are higher than previously thought, but also relatively stable, fluctuating between 1.1 and 1.3 percent of global population from 1990 to 2015.<\/p>\n
In addition, since 1990 approximately 45 percent of migrants have returned to their home countries, a much higher estimate than other methods.<\/p>\n
“Migration is much more than the place you left and the place you ultimately settled in.”<\/p><\/blockquote>\n
On today’s increasingly crowded globe, human migration can strain infrastructure and resources. Accurate data on migration flows could help governments plan for and respond to immigrants. Yet these figures, when available, tend to be spotty and error-ridden, even in the developed world. Researchers have developed approaches to estimate migration rates, but even the best of these rely on unrealistic assumptions about the mass movement of people and yield migration rates that can fall far below reality.<\/p>\n
