La Prensa .- Census data from the Mexican government indicate an extraordinary decline in the number of Mexican immigrants going to the United States.
The recently released data show that about 226,000 fewer people emigrated from Mexico to other countries during the year that ended in August 2008 than during the previous year, a decline of 25 percent.
All but a very small fraction of emigration, both legal and illegal, from Mexico is to the United States.
Because of surging immigration, the Mexican-born population in the United States has grown steeply year after year since the early 1990s, dipping briefly only after the attacks of Sept. 11, 2001, census data in both countries show.
Mexican and American researchers say that the current decline, which has also been manifested in a decrease in arrests along the border, is largely a result of Mexicansâ€™ deciding to delay illegal crossings because of the lack of jobs in the ailing American economy.
The trend emerged clearly with the onset of the recession and, demographers say, provides new evidence that illegal immigrants from Mexico, by far the biggest source of unauthorized migration to the United States, are drawn by jobs and respond to a sinking labor market by staying away.
â€œIf jobs are available, people come,â€ said Jeffrey S. Passel, senior demographer at the Pew Hispanic Center, a nonpartisan research group in Washington. â€œIf jobs are not available, people donâ€™t come.â€
The net outflow of migrants from Mexico â€” those who left minus those who returned â€” fell by about half in the year that ended in August 2008 from the preceding year. The figures are based on detailed household interviews conducted quarterly by the census agency in Mexico, the National Institute of Statistics and Geography.
Along the border, the signs of the drop-off are subtle but ubiquitous. Only two beds are filled in a shelter here that houses migrants hoping to sneak into the United States. On the American side, near Calexico, Calif., Border Patrol vans return empty to their base after agents comb the desert for illegal crossers.
In recent weeks, the spread of swine flu in Mexico and the governmentâ€™s response of shutting down schools and canceling public gatherings brought migration here and elsewhere nearly to a halt. But demographers expect the deep flu-related decline to be temporary.
With so many Mexicans remaining in their home villages, the population of illegal immigrants in the United States stopped growing and might have slightly decreased in the last year, an abrupt shift after a decade of yearly influxes, research by demographers in the United States shows. Mexicans account for 32 percent of immigrants in the United States, and more than half of them lack legal status, the Pew center has reported.
Still, at least 11 million illegal immigrants remain in the United States, the demographers say. Despite collapsing job markets in construction and other low-wage work, there has been no exodus among Mexicans living in the United States, the Mexican census figures show. About the same number of migrants â€” 450,000 â€” returned to Mexico in 2008 as in 2007.
Some researchers argue that the drop in crossings from Mexico proves that tough law enforcement at the border and in American workplaces can reduce illegal immigration in times of rising unemployment in the United States. Immigration and Customs Enforcement officials stepped up factory and community raids last year, and the Border Patrol expanded its force by 17 percent in one year, to nearly 17,500 agents.
â€œThe latest evidence suggests that you can reverse the flow,â€ said Steven A. Camarota, a demographer at the Center for Immigration Studies, a research group in Washington that calls for reduced immigration. â€œIt is not set in stone, so with some mix of enforcement and the economy, fewer will come and more will go home.â€
But Wayne Cornelius, the director of the Center for Comparative Immigration Studies at the University of California, San Diego, predicted that if the United States job market revived, border enforcement would become much less of a deterrent.
The center has documented the causes of the decrease in Mexican migration though interviews this year with more than 1,000 Mexicans in California and in a YucatÃ¡n village that has been a source of migrants. In the interviews, all of the Mexicans who did set out from YucatÃ¡n for the United States reported that they eventually succeeded in crossing.
Mexicans are â€œnot forgoing migration forever,â€ Professor Cornelius said. â€œThey are hoping that the economy in the United States will improve.â€
