The population of unauthorized workers in the United States declined in the year ending January 2009, according to a new report from the Department of Homeland Security.
An estimated 10.8 million unauthorized immigrants were in the country in January 2009 compared with 11.6 million the previous year.
That decrease — nearly 7 percent — is probably related to the country’s declining economy in the first year of the recession. Other scholars have found a correlation between arrests at the Mexican border and labor market in the United States.
