Mexico saw a significant increase in the number of permanent immigrants in 2009, with the level rising by almost 60% to reach close to 24 000. It is unknown what proportion of this is work-related and what is family-related. The United States, China, Guatemala, Colombia and Cuba are the top origin countries, each accounting for about 2 000 to 3 000 immigrants. Following declines in 2007 and 2008, the number of seasonal workers entering Mexico rose by one-third, to 31 000. Most are from Guatemala and Belize.
