A nationally representative sample of eighth-graders were first surveyed in the spring of 1988. A sample of these respondents were then resurveyed through four follow-ups in 1990, 1992, 1994, and 2000. To further enrich the data, students’ teachers, parents, and school administrators were also surveyed. Coursework and grades from students’ high school and post-secondary transcripts are also available in the restricted use dataset – although some composite variables have been made available in the public use file.
The National Health Interview Survey (NHIS) is a multi-purpose health survey
conducted by the National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention (CDC), and is the principal source of information on the health of the civilian noninstitutionalized household population of the United States. The NHIS has been conducted continuously since its beginning in 1957. Public use data files are released on an annual basis.
The National Latino and Asian American Study (NLAAS) provides national information on the similarities and differences in mental illness and service use of Latinos and Asian Americans. The NLAAS is one of the most comprehensive studies of Latinos and Asian Americans ever conducted using up-to-date scientific strategies in the design, sampling procedures, psychiatric assessments, and analytic techniques. The final NLAAS sample consisted of 2,554 Latino respondents and 2,095 Asian American respondents.
The primary goal of the National Politics Study (NPS) was to gather comparative data about individuals’ political attitudes, beliefs, aspirations, and behaviors at the beginning of the 21st century. Exploring the nature of political involvement and participation among individuals from different racial and ethnic groups, the survey included questions about voting preferences, party affiliation, organizational membership, immigration, racial consciousness, acculturation, and views of government policies.
The National Survey on Drug Use and Health (NSDUH) series (formerly titled National Household Survey on Drug Abuse) primarily measures the prevalence and correlates of drug use in the United States. The surveys are designed to provide quarterly, as well as annual, estimates. Information is provided on the use of illicit drugs, alcohol, and tobacco among members of United States households aged 12 and older. Questions included age at first use as well as lifetime, annual, and past-month usage for the following drug classes: marijuana, cocaine (and crack), hallucinogens, heroin, inhalants, alcohol, tobacco, and non-medical use of prescription drugs, including pain relievers, tranquilizers, stimulants, and sedatives. The survey covered substance abuse treatment history and perceived need for treatment, and included questions from the Diagnostic and Statistical Manual (DSM) of Mental Disorders that allow diagnostic criteria to be applied.
The 21st Century Americanism survey was conducted to study (1) the multidimensional nature of American identity (“Americanism”); (2) resentment among Whites toward immigrants, Latinos, and Asians, fueled by perceptions that these groups violate the cherished norms that constitute American identity (“symbolic nativism”); (3) how perceptions of discrimination affect the process of “becoming American” among ethnic minorities (“reactive ethnicity”); and (4) the relationships among these issues and public opinion on policies that address ethnic change. The data collection began in July 2004 and was completed by October 2004.
