The Pew Hispanic Center conducted an unprecedented survey of Mexican migrants in the United States, including thousands who say they have no U.S.-issued identity documents. The survey provides detailed information on the demographic characteristics, living arrangements, work experiences and attitudes toward immigration of Mexican adults who completed a 12-page questionnaire as they were applying for a matrícula consular, an identity document issued by Mexican diplomatic missions.

Fieldwork was conducted in Los Angeles, New York, Chicago, Atlanta, Dallas, Raleigh, NC, and Fresno, CA.
