The Mexican American Study Project II (MASP II), 1998-2000 (ICPSR 28481)

Principal Investigator(s): Ortiz, Vilma, University of California-Los Angeles; Telles, Edward E., Princeton University


In an original study conducted in 1965, Leo Grebler, Joan Moore, and Ralph Guzman surveyed Mexican Americans in San Antonio, Texas, and Los Angeles, California. The first survey provided a rich cross-sectional view of this population's demographics and attitudes, Ortiz and Telles' 35 year follow-up now allows for a longitudinal view of the behavior and ethnic identification of first- through fourth-generation Mexican Americans in these areas. The new survey was used to test hypotheses related to Mexican Americans' social mobility, their ethnic identity and behavior, their experiences with discrimination, and the relationship between socioeconomic status and ethnic identity. Data includes birth dates, citizenship information, education, income, housing, language, medical, religious affiliations, immediate and extended family demographic information, and self perception in regards to ethnicity. There are four versions of the survey, "Child Respondents" in English and Spanish and "Informant Respondents" in English and Spanish. Additionally each survey includes an interviewer questionnaire, which asks interviewers to document their observations of the respondent's home (interior and exterior), cooperation, behavior, language proficiency, and gender.
