The Detroit Arab American Study (DAAS), 2003, a companion survey to the 2003 Detroit Area Study (DAS), using a representative sample (DAS, n = 500) drawn from the three-county Detroit metropolitan area and an oversample of Arab Americans (DAAS, n = 1000) from the same region, provides a unique dataset on September 11, 2001, and its impacts on Arab Americans living in the Detroit metropolitan area. The data contain respondent information concerning opinions on their experiences since the September 11, 2001, attacks on the World Trade Center and the Pentagon, social trust, confidence in institutions, intercultural relationships, local social capital, attachments to transnational communities, respondent characteristics, and community needs. Examples of the issues addressed in the data include frequency of religious participation, level of political activism, level of interaction with people outside of their cultural, racial, and ethnic groups, and the quality of the social and political institutions in their area. Background information includes birth country, citizenship status, citizenship status of spouse, education, home ownership status, household income, language spoken in the home (if not English), marital status, number of children (under 18) in the household, parents' countries of birth and citizenship status, political affiliation, total number of people living in the household, voter registration status, whether the respondent ever served in the United States Armed Forces, and year of immigration, if not born in the United States.
