The number of foreign-born residents in Mexico rose 13% from 2009 to 2010, from 860 000 to 961 000. Since 2000, the foreign-born population has doubled, although most of the foreign-born are Mexican citizens, as inflows of foreigners over the past decade have been more limited. Permanent immigration of foreigners to Mexico increased by almost 10% in 2010 compared with 2009, to around 26 000 persons. The top origin countries were the United States, (4 000 immigrants), followed by Colombia, Cuba, Guatemala and China, (about 2 000 immigrants each). The number of seasonal workers entering Mexico in 2010 decreased by 10% on an annual basis, to 27 400, almost all from Guatemala.
