(Press-News.org) Unauthorized immigrants who previously have been removed from the United States are more than 2.5 times more likely to be rearrested after leaving jail, and are likely to be rearrested much more frequently than those who have never been removed, according to a new RAND Corporation study.
The findings generally support strategies adopted by federal immigration authorities and some law enforcement agencies to focus their immigration enforcement efforts on immigrants who previously have been removed, who are viewed as posing a bigger criminal threat.
Researchers studied long-term recidivism rates among two groups of removable immigrants who had been released from the Los Angeles County jail: men who previously had been removed from the United States and men who had never been removed from the nation.
Published online in the journal Criminal Justice Policy Review, the study followed 517 foreign born men for nine years, and found that 91 percent of those who had a prior record of removal from the U.S. were rearrested during the study period compared to 64 percent of those with no history of removal. They also were arrested sooner following their jail release, and more frequently -- 4.5 times compared to 2.9 times -- than those who had never been removed from the U.S.
"If you are trying to target individuals who repeatedly cycle through the criminal justice system, this looks like a good risk marker," said lead author Laura Hickman, a professor of criminology and criminal justice at Portland State University and a researcher at RAND, a nonprofit research organization. "At least in our study, previous removal does seem to indicate something about increased likelihood for continuing criminal justice involvement."
An earlier study by Hickman and her colleagues showed that previous removal was a high risk factor for recidivism in the short term, with men who had a history of removal about twice as likely to be rearrested within a year of their jail release.
But short-term differences in recidivism don't necessarily predict long-term differences. To test whether previous removal continues to be a risk factor over the long term, researchers extended the study for an additional eight years. All men tracked in the study were released from the L.A. County jail between Aug. 4, 2002, and Sept. 2, 2002.
Removable immigrants are individuals who entered the country without authorization or the authorization they had has been revoked or expired, such as overstaying their visas. Federal immigration records were used to determine the men's immigration status to identify those removed prior to the 2002 Los Angeles County Jail stay. The researchers controlled for factors such as prior criminal history, age and current criminal charges.
In discussion of the comparison group findings (those without a record of prior removal), Hickman notes, "While 64 percent rearrested may seem very high, it's important to remember that this is a nine-year follow-up study. Other research on the entire Los Angeles County jail population found that 50 percent of released inmates were rearrested after just one year." Given the lack of other long term follow-up studies with similar populations, Hickman said "this prior research gives us a basis to suggest that 64 percent over nine years may not be too different from the population overall." Without additional study, however, "we just don't know."
After the data were collected in 2002, the U.S. Department of Homeland Security poured resources into border security and began a program known as Secure Communities, which screened all arrestees at local jails for immigration status and potential removal from the United States.
In its November executive action on immigration, the Obama administration announced an end to the Secure Communities program, which was criticized by groups opposed to local law enforcement participating in immigration enforcement. The Security Communities effort will be replaced by the Priority Enforcement Program, which will target interior immigration efforts more narrowly on those posing a distinct public safety risk.
"Since there are very few studies of unauthorized immigrants in local criminal justice populations, our results may be helpful information for the new Priority Enforcement Program," Hickman said. "In our data, it's clear that prior removal represents a solid predicator of repeat arrest over pretty long follow-up period, even taking into account criminal history."
Hickman notes, however, that more study is needed to confirm these results in other settings.

Unlike in mathematics, it is rare to have exact solutions to physics problems.
"When they do present themselves, they are an opportunity to test the approximation schemes (algorithms) that are used to make progress in modern physics," said Michael Strickland, Ph.D., associate professor of physics at Kent State University.
Strickland and four of his collaborators recently published an exact solution in the journal Physical Review Letters that applies to a wide array of physics contexts and will help researchers to better model galactic structure, supernova explosions ...
The genetic abnormality that drives the bone cancer Ewing sarcoma operates through two distinct processes - both activating genes that stimulate tumor growth and suppressing those that should keep cancer from developing. These findings by Massachusetts General Hospital (MGH) investigators, published in the November issue of Cancer Cell, may lead to new therapies targeting these aberrant mechanisms.
The second most common bone cancer in children and young adults, Ewing sarcoma is caused by a chromosomal translocation - switching of genetic segments between two different ...
EAST LANSING, Mich. - 'Tis the season of plenty of food and drink. While celebrating should be joyful, for some women, it's not. All the holiday temptations can add another layer to an already complicated biological process.
It's well known that women undergo hormonal changes every month due to the menstrual cycle. These changes can cause women to eat more, which is a natural, biological occurrence.
However, Michigan State University Foundation Professor Kelly Klump has found that the increased food intake causes some women to become much more preoccupied with their ...
ITHACA, N.Y. - In the fight against global warming, carbon capture - chemically trapping carbon dioxide before it releases into the atmosphere - is gaining momentum, but standard methods are plagued by toxicity, corrosiveness and inefficiency. Using a bag of chemistry tricks, Cornell materials scientists have invented low-toxicity, highly effective carbon-trapping "sponges" that could lead to increased use of the technology.
A research team led by Emmanuel Giannelis, the Walter R. Read Professor of Engineering in the Department of Materials Science and Engineering, has ...
HOUSTON -- (Dec. 16, 2014) -- In one of the most comprehensive laboratory studies of its kind, Rice University scientists traced the uptake and accumulation of quantum dot nanoparticles from water to plant roots, plant leaves and leaf-eating caterpillars.
The study, one of the first to examine how nanoparticles move through human-relevant food chains, found that nanoparticle accumulation in both plants and animals varied significantly depending upon the type of surface coating applied to the particles. The research is available online in the American Chemical Society's ...

DURHAM, N.C. - Duke University scientists have developed new forensic tracers to identify coal ash contamination in water and distinguish it from contamination coming from other sources.
"These new tools can be used by federal and state regulatory agencies to monitor the environmental effects of coal ash and determine whether it has or hasn't impacted the environment," said Avner Vengosh, professor of geochemistry and water quality at Duke's Nicholas School of the Environment. "They can be used to trace the coal ash effluents to their source, even in watersheds where ...
Washington, D.C.--New work from Carnegie's Ivan Naumov and Russell Hemley delves into the chemistry underlying some surprising recent observations about hydrogen, and reveals remarkable parallels between hydrogen and graphene under extreme pressures. Their work is the cover story in the December issue of Accounts of Chemical Research.
Hydrogen is the most-abundant element in the cosmos. With only a single electron per atom, it is deceptively simple. As a result, hydrogen has been a testing ground for theories of the chemical bond since the birth of quantum mechanics ...
MINNEAPOLIS/ST. PAUL (12/16/2014)--A new study by an international team of researchers shows for the first time that people may inherit some of the intestinal bacteria that cause Crohn's disease and ulcerative colitis, collectively know as inflammatory bowel disease (IBD). The study, recently published in Genome Medicine, also confirmed that antibiotics could worsen the imbalance in the gut microbes.
About 1.6 million Americans suffer from Crohn's disease or ulcerative colitis, according to the Crohn's and Colitis Foundation of America. Understanding the causes of these ...
AMHERST, Mass. - In a follow-up to her earlier studies of learning in infancy, developmental psychologist Lisa Scott and colleagues at the University of Massachusetts Amherst are reporting that talking to babies in their first year, in particular naming things in their world, can help them make connections between what they see and hear, and these learning benefits can be seen as much as five years later.
"Learning in infancy between the ages of six to nine months lays a foundation for learning later in childhood," Scott says. "Infants learn labels for people and things ...
