America is losing as many illegal immigrants as it’s gaining

By Douglas S. Massey

You’d never know it from the Republican primary debates, but for the first time in more than four decades, illegal migration from Mexico has fallen to a net zero. All data indicate that the undocumented population of the United States is no longer growing. According to estimates from the U.S. Department of Homeland Security, that population peaked at around 12 million in 2008, fell to 11 million in 2009 and has remained constant since then. Independent estimates prepared by the Pew Hispanic Trust show the same thing, and Mexican census data reveal unusually large numbers of former U.S. migrants remaining home rather than heading northward.

These population estimates are consistent with individual-level data collected by the Mexican Migration Project, a binational program I co-direct that has been surveying legal and unauthorized migrants on both sides of the border for 30 years. Statistical analyses reveal that the rate of new migration to the United States is essentially zero, while repeat visits by returned migrants are rare. In keeping with these calculations, border apprehensions have fallen to the lowest number since 1970 despite the fact that there are more Border Patrol agents on duty than ever.

Surprisingly, this turn of events does not likely have anything to do with border enforcement. Historically, the volume of undocumented migration is uncorrelated with the size or budget of the Border Patrol. According to a recent assessment by the National Academy of Sciences, studies of migrant behavior “generally show that rising enforcement has little deterrent effect on undocumented migration,” which instead reflects the economic trends in Mexico and the United States and ongoing opportunities for legal entry to the U.S.

Demand for labor plummeted in the United States during the Great Recession, of course. That was especially the case in residential construction, which had been a key driver of migration beforehand. Between 2007 and 2010, Hispanics lost 764,000 jobs in the construction industry alone. Despite America’s recession, however, economic conditions in Mexico did not deteriorate very much. Although Mexican exports to the U.S. initially sagged, after 2009 they surged to surpass the 2008 level by 22 percent on strong sales of oil, tourism, crops and manufactured products, allowing many Mexicans to stay home rather than leave for the U.S. Mexican labor force growth has also slowed dramatically because of a sharp drop in fertility over the past two decades. That contributed to a rise in education levels among young Mexicans, who increasingly see opportunities at home.

Although labor demand continues in agriculture and other U.S. sectors, it has increasingly been fulfilled by legal temporary workers, whose entries rose to a record 517,000 in 2010. Permanent legal immigration, meanwhile, has averaged 165,000 entries per year since 2008. With so many opportunities for legal entry, slowing labor force growth and steady employment in Mexico, and stagnant labor demand in the United States, illegal migration has effectively ceased.

Net zero migration doesn’t just mean undocumented migrants are staying in Mexico; it also means those already here aren’t going home, in large part because the increase in border enforcement did have a very real effect, just not the intended one. Rising border enforcement naturally drove up the costs and risks of border crossing, and migrants quite logically decided to stop crossing the border – not by remaining in Mexico but by hunkering down and staying in the United States once they had made it across.

From 1986 to 2006 the probability of returning to Mexico within a year of illegal entry fell from 60 percent to around 15 percent. Instead of slowing the rate of undocumented entry, therefore, the militarization of the border reduced the rate of undocumented departure, creating the present stalemate. Undocumented Mexicans are no longer coming to the United States, but those already here are increasingly unlikely to leave.

With illegal migration stopped, temporary legal migration at record levels, and legal permanent immigration running between 150,000 and 200,000 people per year, the only real issue remaining for immigration reform is what to do about the well-rooted population of 11 million residents already here.

The longer Americans put off the day of reckoning, the worse it will be. Undocumented migrants now make up a large share of America’s most rapidly growing minority group. Among all migrants from Latin America, around 40 percent are currently undocumented, but the figure is 58 percent for Mexicans and even greater for Central Americans, whose undocumented ranks continue to edge up slightly.

Of the 11 million undocumented residents now present, upwards of 3 million entered as children. They grew up here, speak English and have graduated from high school, and the vast majority have stayed out of trouble. Against the odds many have even attended college. Yet until the burden of illegality is lifted from their shoulders, they have nowhere to go in the legitimate economy of the only country they know.

Among those who became undocumented as adults, most have jobs, lives, houses and children born in the United States. For these people the only humane and practical course of action is an earned legalization program in which immigrants are granted temporary legal status and allowed to become permanent legal residents once they have fulfilled certain criteria, such as taking courses in English, studying U.S. history, establishing a history of employment, consistently paying taxes and having a clean criminal record.

Once they have satisfied these criteria, they can be levied a fine to pay their debt to society and allow them to get on with their lives. For years, conservatives have argued that reform must be put off until the border is “under control.” With illegal migration at net zero, that moment has arrived. Unless we take such action soon, we are in grave danger of building a new Latino underclass in the United States.

Now is this a real number, or a real thing that you say in this article. I suspect this is more Obama smoke that I see.

Even your article intimates that these immigrants remain or leave the US due to the economic conditions in both countries.

What that says to me is that these people are still here because they hold down jobs that American citizens could easily take in this so-called worst recession since the Great Depression — and no, don’t even argue that none of them are holding down US citizen’s jobs because that is a lie.

To me it is unconscionable to argue that “the only humane and practical course of action is an earned legalization program in which immigrants are granted temporary legal status and allowed to become permanent legal residents once they have fulfilled certain criteria”.

What about considering the most humane course of action for our own citizens first!

When it is costing U.S. taxpayers 124 billion dollars a year to support illegal immigration not enough have left to satisfy me.

When statics show that over 60% of so called Hispanics are not graduating from High School, this would indicate that we already will have another generation of gardeners, house keepers, crop pickers and fast food workers to meet our needs for the next 40 years. So close the borders now. Your article to me is very one sided are you related to Obama?

“According to estimates from the U.S. Department of Homeland Security, that population peaked at around 12 million in 2008, fell to 11 million in 2009 and has remained constant since then. ”

If that estimate is as accurate the ones in the 80′s, we only actually have 40 or 50 million illegal aliens in this country.

Wigglwagon, if you believe anything that D.H.S. says, you are pretty naive. I have a 2012 Lincoln I’ll sell you for $99.99.

The steady drip of amnesty plans from Senators Durbin, Schumer, Reid, Obama and others are the motive for many here illegally to stay. The humane and reasonable thing to do is to prioritize those here longer than ten years (with sound documented proof and no records of arrest) on our existing guest worker programs. All else must return home. No citizenship, simply the chance to stay legally and work (as needed). The law allowing children born of undocumented immigrants is an abuse and must end now.

Passage and enforcement of e-Verify is the most humane, cost effective and reasonable way to vastly reduce illegal immigration. Simply put, most of those here illegally who can not get jobs will leave, and once that is understood, far fewer will enter (even when the economy recovers). No need for mass round ups….just enforce e-Verify. Unfortunately, Senators Durbin and Schumer (and Obama) oppose this simple plan and instead push for a mass amnesty under the DREAM Act. This plan, simply put, allows almost anyone here illegally to remain for virtually any reason, and to sponsor their relatives too. Their goal is to win hispanic voters while throwing American citizens under the bus. It’s criminal.

And do you know why Mr. Massey that the number of illegals is no longer sky rocketing? It’s the economy. So one could say that Obama has helped the illegal immigration problem a lot by destroying the economy. Its a fair statement, it’s just not quite the solution non-Obamaphiles had in mind.

The USA should enforce the same laws
Mexico uses to protect the border and regulate foreign workers.
