WASHINGTON -- Illegal immigration is increasing despite tighter border security, and illegal immigrants now outnumber foreigners who move to the United States legally, according to a Pew Hispanic Center report.
The total number of immigrants to the United States declined after the Sept. 11, 2001, terrorist attacks, partly because of increased security measures, the center reported yesterday. The 2001 recession also was a likely factor, reducing jobs available in the United States.
Now the number coming to the country is on the upswing again.
Immigration, both legal and illegal, topped 1.5 million people in 1999 and 2000, according to the report. The number of people entering the United States then plummeted to 1.1 million people by 2003, the same level as in 1992.
Immigration bounced back to 1.2 million in 2004, but the report cautioned that it is difficult to say whether the recent upswing is part of a trend.
''The extremely high [immigration] flows at the end of the past decade were not the norm, nor part of a long-term trend, but rather the peak of a momentary increase that lasted for only a few years," said the report, by demographer Jeffrey Passel and Roberto Suro, a former journalist who is director of the Pew Hispanic Center.
The report documents immigration levels from 1992 to 2004, generating estimates from a variety of Census data.
The Pew Hispanic Center is a nonpartisan research organization supported by the Pew Charitable Trusts.
Border security gained national attention last month after the governors of two states, Arizona and New Mexico, declared states of emergency on their borders with Mexico. The governors cited security shortcomings by the federal government.
Homeland Security Secretary Michael Chertoff said at the time that he had already ordered a review of border security strategy.
''The Pew report is yet another indicator that the immigration system is broken," said a statement by John Cornyn, chairman of the Senate's Immigration, Border Security and Citizenship Subcommittee. ''Immigration reform must be comprehensive and address both enforcement and improved avenues for legal immigration."
The Texas Republican has coauthored a bill that would create a temporary worker visa, as well as a mandatory system for employers to check on the immigration status of prospective employees.
The Pew report said immigration levels closely mirror economic conditions in the United States -- as the economy improves, immigration increases -- suggesting that the lure of jobs is a strong factor in attracting people to this country.
Among the report's findings:
Since 2001, the number of legal permanent residents entering the United States has declined from 578,000 to 455,000, while the number of illegal immigrants has increased from 549,000 to 562,000. Legal, temporary residents account for the remainder of the people entering the country.
Mexico accounted for about a third of all US immigrants, a percentage that was steady from 1992 to 2004. Other Latin American countries accounted for about 20 percent of all immigrants, Asia accounted for a little more than a quarter, and Europe and Canada combined to account for about 14 percent.
