The California Health Interview Survey (CHIS) is the largest state health survey in the nation. It is a random-dial telephone survey that asks questions on a wide range of health topics. CHIS is conducted on a continuous basis allowing it to provide a detailed picture of the health and health care needs of California’s large and diverse population. A full data cycle takes two years to complete, with over 50,000 Californians surveyed. Continuous data collection allows CHIS to generate timely one-year estimates. CHIS is conducted by the UCLA Center for Health Policy Research in collaboration with the California Department of Public Health, and the Department of Health Care Services.
Children of Immigrants Longitudinal Study (CILS) was designed to study the adaptation process of the immigrant second generation which is defined broadly as United States-born children with at least one foreign-born parent or children born abroad but brought at an early age to the United States. The original survey was conducted with large samples of second-generation immigrant children attending the 8th and 9th grades in public and private schools in the metropolitan areas of Miami/Ft. Lauderdale in Florida and San Diego, California.
The Education Longitudinal Study of 2002 (ELS :2002) is designed to monitor the transition of a national sample of young people as they progress from tenth grade through high school and on to post-secondary education and/or the world of work.
As a longitudinal study, ELS: 2002 follows a nationally representative cohort of students from the time they were high school sophomores through the rest of their high school careers.
Since 1991, the Russell Sage Foundation has funded a program of research aimed at assessing how well the young adult offspring of recent immigrants are faring as they move through American schools and into the labor market. Two previous major studies have begun to tell us about the paths to incorporation of the children of contemporary immigrants: The Children of Immigrants Longitudinal Study, and the Immigrant Second Generation in New York study. The Immigration and Intergenerational Mobility in Metropolitan Los Angeles study is the third major initiative analyzing the progress of the new second generation in the United States.
The study analyzes the forces leading to or impeding the assimilation of 18- to 32-year-olds from immigrant backgrounds that vary in terms of race, language, and the mix of skills and liabilities their parents brought to the United States. To make sure that what we find derives specifically from growing up in an immigrant family, rather than simply being a young person in New York, a comparison group of people from native born White, Black, and Puerto Rican backgrounds was also studied.
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 Longitudinal Study of Adolescent Health (Add Health) is a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-1995 school year. The Add Health cohort has been followed into young adulthood with four in-home interviews, the most recent in 2008, when the sample was aged 24-32. Add Health combines longitudinal survey data on respondents’ social, economic, psychological and physical well-being with contextual data on the family, neighborhood, community, school, friendships, peer groups, and romantic relationships, providing unique opportunities to study how social environments and behaviors in adolescence are linked to health and achievement outcomes in young adulthood.
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.
