A Mexican government survey shows a sharp drop in emigration.
The National Statistics and Geography Institute says about eight of every 1,000 Mexicans left to live abroad between February and May of this year. That's a 42 percent drop from the same period in 2006.
In all of 2007, some 814,000 Mexicans left the country, compared to 1.2 million in 2006.
Mexican and U.S. officials cite America's economic downturn and tighter border security. The vast majority of Mexican migrants go to the United States.
The U.S. Border Patrol also has reported a drop in the capture illegal immigrants along the border.
