Why people take the risk of illegal immigration

USC (US) — Threats of arrest and punishment aren’t enough to deter illegal immigrants, according to new research that considers non-economic reasons people migrate.

“This suggests that perhaps there is very little that immigration enforcement alone might be able to do to affect changes in people’s intentions to migrate illegally,” says study author Emily Ryo, USC law professor and a research fellow at Stanford Law School’s Program in Law & Society.

The study, published in the American Sociological Review, relies on data from the 2007 and 2008 Mexican Migration Project (MMP) and Becoming Illegal Survey (BIS).

MMP is a unique source of data that enables researchers to track patterns and processes of contemporary Mexican migration to the United States. Each year, a random sample of 150 to 200 households is drawn from a selected number of communities in Mexico and interviewed during the winter months. The BIS is an individual survey of 15 to 65-year-old men from these households who work or intend to work in Mexico or the US in the next year. More than 1,600 men participated in the BIS.

Deciding to cross

“If you ask an average person, why are there so many unauthorized migrants in the US, the typical story that you might get is something like this: people are looking for better jobs, better economic opportunities—for themselves and their families—and our immigration enforcement just isn’t tough enough to stop them; so, here they are,” Ryo says.

“But this conventional story misses a critical point, because economic incentives alone typically do not induce otherwise law-abiding people to violate the law. And, my study shows that unauthorized migrants are no different.”

Ryo found that while cost-benefit calculations such as perceptions of job availability in Mexico and dangers of crossing the border do play a significant role in Mexicans’ decisions about whether to enter the US illegally, non-economic factors matter as well.

“For example, perceptions about the legitimacy of US legal authority, the morality of violating US immigration laws, and social norms on illegal border crossings are significantly related to people’s intentions to migrate illegally,” she says.

Moral ground

According to the study, one of the strongest non-economic determinants of intentions to migrate illegally is whether people have friends or family members who have tried to cross into the US illegally. “Communities with a long history and high prevalence of out-migration might have a culture of migration and, for many young men, migration can be seen as a rite of passage,” Ryo says.

She also found that the odds of intending to migrate illegally were more than doubled for individuals who believed that Mexicans have a right to be in the United States without the US government’s permission.

Interestingly, the vast majority—78 percent—of people says it is not okay to disobey the law when one disagreed with it. However, 55 percent says that disobeying the law is sometimes justified.

“This study offers insights into how unauthorized migrants justify their violation of US immigration law, and how such justifications might make noncompliance with this particular law possible among otherwise law-abiding individuals,” Ryo says. “People generally see themselves as moral beings who want to do the right thing as they perceive it.”

In a companion project in which Ryo carried out open-ended group interviews with unauthorized migrants and migrants who were about to cross the US-Mexico border illegally, she found that these individuals viewed themselves as moral, law-abiding people who respected national borders, despite their violation of US immigration laws.

“This is because they see their decision to cross illegally as an affirmation of their moral obligation to their families to get through situations that were brought on through no fault of their own, such as a crop failure or an economic downturn in their community,” Ryo says.

Invest in ‘sender’ communities

The current study, which comes at a pivotal moment for immigration—as the Obama administration has vowed change on the immigration front and the US Senate recently passed an immigration reform bill—has important policy implications, Ryo says.

“My findings, for example, suggest that one way to reduce unauthorized migration, insofar as that is the desired goal, could be to reallocate some of our current enforcement resources to increasing our investment in employment-generating economic development of key sending communities, which might make staying at home both an economically-viable as well as a morally-acceptable option for prospective migrants,” Ryo says.

Another policy implication relates to her findings on would-be unauthorized migrants’ perceptions of legitimacy, or lack thereof, of the US immigration system. “Again, insofar as greater compliance with the law is the goal, one way to achieve that goal in the long-run might be through enhancing perceptions of legitimacy of the US immigration system,” she says.

There are a number of ways in which prospective unauthorized migrants view the US immigration system as not operating fairly and neutrally and, thus, functioning illegitimately, Ryo says.

For example, one widespread perception is that there is racial bias. “This is not surprising given that racial profiling in immigration enforcement under certain circumstances is a legally-sanctioned practice under Fourth Amendment jurisprudence,” she says.

“Countering these kinds of widespread perceptions of racial bias among prospective migrants would require, at a minimum, a careful reconsideration of these kinds of racial profiling practices.”

    Why should we have to do this when Mexico has enough wealth to do it themselves?? How long are we going to be Mexico’s patsy?? It’s no wonder illegal aliens come here with no respect for America! They come from a country that has no respect for America – but will certainly take our money, though!

    No. What we need to do is to GET REAL SERIOUS about our border security and interior enforcement! We need a hard hand approach with illegals because right now they do not fear our threats – because we don’t back them up!

    And what would that entail? we arevery stict with our borders we deport more people then anyother country. What else are we to do? shoot them? No we need to do this smartly, make legal immigration more beneficial to us and them. Only when they loose their reasons for crossing illegally will they stop taking the risk.

    I know if my family was starving fear of death wouldn’t stop me from trying to feed them, and if the best way to do that is to cross illegal well.

    I still dont understand yet what problem is. People migrate to America from overseas successfully all the time. Why arent Mexicans successfully legally migrating? Also why are Mexicans giving up on developing Mexico? Im not sure either country can survive with a mass consensus to just evacuate Mexico. Perhaps we need more Peace Corps and other American aid sent to Mexico rather than securing our borders furthers or doing immigration reform.

    I cannot roll my eyes harder at the first comment. It’s obvious you know nothing about what it feels like to be stuck in a place where you’re only options seem to be A) be ignored and abused by your government
    B) live in a miserable amount of poverty
    Those who are brave enough to come to the US having nothing but respect for the country. Oh and btw they don’t take money, they get jobs

    As a nurse, during the 8 years I worked in the ER, the Mexican (and others from other poor or oppressive countries) immigrants were among the most polite, thankful, grateful people I took care of. When it came time to check out, they’d do their best to attempt to pay the bill even if it meant emptying the last two dollars and change from their pockets. On the other hand quite often the uninsured Americans made no attempt (I forgot my wallet, I ain’t got no money, with a tone suggestive they were entitled to service and shouldn’t have to pay a dime) at all. The immigrants would pay $5 a week if that’s all they could afford. The Americans would rack up tens of thousands and never make any attempt to pay. Understand it’s expensive, but I appreciated the gratefulness of the immigrants. They were always polite and thankful for the care they received, never demanding or barking orders as if I was there to cater to their every whim.
