Migration inflows to the Russian Federation in 2011 almost doubled over 2010, to 356 000 people, while the outflow of migrants remained comparatively small (33 500 persons). The dramatic increase is partially due to a change in methodology which Rosstat implemented in 2011. Rosstat now includes migrants registered in a certain locality for nine months or more, in addition to the traditional method of counting migrants registered at their place of residence. Temporarily-registered residents are considered emigrants when their registered residence expires. While the methodology has changed, the general trend remains: decreasing flows from Kazakhstan and Ukraine, and increasing flows from other countries in Central Asia. Most international migration in the Russian Federation is temporary. Temporary labour migration flows are normally at least three times higher than permanent-type flows.
