This survey was designed to investigate whether having psychological connections to particular groups (ex: racial, ethnic, and national origin groups) and perceptions of discrimination lead to alienation from the structure and operation of representative democracy in the United States. The data allow for comparative ethnic analyses of people's views regarding the representative-constituent relationship and of the conditions under which group identifications and perceptions of discrimination matter.

The survey includes oversamples of Black, Latino, and Asian respondents. A Spanish version of the survey was available. Demographic information retrieved about respondents include age, race/ethnicity, gender, education (highest degree received), employment status, marital status, religion, household size and income. In addition, ancestry was assessed with the question, "From what countries or parts of the world did your ancestors come?" Respondents also reported United States citizenship status, primary home language, and nationality. Variables focusing on respondent perceived representation in the United States include political ideology and political party affiliation.

The 2012 Collaborative Multi-racial Post-election Survey (CMPS) was a national survey of registered voters from three groups: White non-Hispanic adults, Black non-Hispanic adults, and English and Spanish speaking Hispanic adults. The survey was conducted between November 16, 2012 and November 26, 2012 in both English and Spanish, and examined individual's experiences with voting and attitudes about social and economic issues prominent in the 2012 election.

The 2012 CMPS included 37 items dealing with sociopolitical attitudes, mobilization political activity, advertising exposure and neighborhood context as well as three embedded survey experiments. Additionally, there were 15 items that capture demographic information, including: age, ancestry, birthplace, education, ethnicity, Latin American racial descriptors, skin color, marital status, household size, religiosity, gender, sexual orientation, internet usage, and residential context. Geographic variables below state level, such as city, county, Metropolitan Statistical Area (MSA) level, and Congressional district, are only available within the restricted-use data file for this collection.

In spring 2016, scholars were invited to collaborate on the 2016 Collaborative Multi-Racial Post-election Survey (CMPS). The goal of the project was to create the first cooperative, 100% user content driven, multi-racial, multiethnic, multi-lingual, post-election online survey in race, ethnicity and politics (REP) in the United States. The survey's main focus is on attitudes about the 2016 election and candidates, debates over immigration, policing, and racial equality, and experiences with racial discrimination across many facets of American life.

Questions were user-generated from a team of 86 social scientists across 55 different universities who placed questions on the survey. Users could submit questions for just one single racial group, or common questions across all four racial groups, depending on their interest. In cases where two different users submitted very similar questions the PIs worked to create a single common question. Overall, the survey contains 394 questions.

The restricted-use dataset contains geographical information which has been masked in the public-use dataset along with adjustments to date information. Please refer to the Collection Notes in the SCOPE OF PROJECT section for more information.

In spring 2020, scholars were invited to collaborate on the 2020 Collaborative Multi-Racial Post-election Survey (CMPS). The goal of the project was to build upon the 2016 CMPS which was the first cooperative, 100% user content driven, multi-racial, multi-ethnic, multi-lingual, post-election online survey in Race, Ethnicity and Politics (REP) in the United States. The survey's main focus is on attitudes about the 2020 Election and candidates, experiences with racism, policy attitudes, immigration, and personal experiences with civic engagement across many facets of American life.

This 2020 CMPS includes over 200 scholars across nearly 100 different colleges/universities. Survey questions were user-generated. Users who contributed survey content could submit questions for just one single racial group, or common questions across all racial/ethnic, or oversample groups, depending on their interest. In cases where two different users submitted very similar questions the PIs worked to create a single common question. Overall, the survey contained over 800 unique questions including split samples, branch-items, and group-specific questions, and the average respondent completed over 500 items.

The 2020 CMPS was offered in English, Spanish, Chinese (simplified), Chinese (traditional), Korean, Vietnamese, Arabic, Urdu, Farsi and Haitian Creole. The survey dataset includes Black, White, Latino and Asian respondents as well as additional oversamples of respondents from hard-to-reach populations including, Afro-Latinos, Black immigrants, Native Americans, Native Hawaiians, Muslims and people who identify as LGBTQ.

This collection includes a combined dataset of the Generations study wave 1 (baseline) survey and the TransPop study transgender survey. The two studies have many overlapping variables, and they examined topics such as respondents' health outcomes and behaviors, experiences with discrimination, identity, and transition-related experiences. Data from these studies were merged to allow for analysis of the combined LGBT populations. This dataset has also been reweighted to be representative of these populations.

The complete Generations study data (baseline, wave 2, and wave 3 survey data) can be found under study number 37166, and the complete TransPop study data (transgender and cisgender survey data) can be found under study number 37938. For detailed information on the Generations and TransPop studies, including related publications, please refer to their respective DSDR/ICPSR study pages.

In 2015 Ithaka S+R surveyed the grantees of the New York City Department of Cultural Affairs (DCLA) and received demographic data on staff and board members, as well as questionnaire responses about initiatives and barriers to diversifying staff and boards. The invitation to participate in the survey was sent to the executive directors (or equivalent) of the 1,061 DCLA Capital Fund recipients for fiscal year 2016. Survey participation was a requirement for funding eligibility for fiscal year 2017.

Representatives from the responding organization filled out spreadsheets on staff demographics. The spreadsheet results are compiled in the Demographics File which contains information on staff race, ethnicity, gender, disability status, and age. In addition, there are variables on staff members' roles in the organization such as employment status, job level, decade hired, job type, and discipline. The Demographics File contains 14 variables and cases on over 48,000 staff members

The Survey File contains grantee organization representatives' responses to the DCLA questionnaire on diversity engagement, barriers and initiatives. This file contains 993 cases and 62 variables.

The Future of Families and Child Wellbeing Study (FFCWS, formerly known as the Fragile Families and Child Wellbeing Study) follows a cohort of nearly 5,000 children born in large, U.S. cities between 1998 and 2000. The study oversampled births to unmarried couples; and, when weighted, the data are representative of births in large U.S. cities at the turn of the century. The FFCWS was originally designed to address four questions of great interest to researchers and policy makers:

1. What are the conditions and capabilities of unmarried parents, especially fathers?
2. What is the nature of the relationships between unmarried parents?
3. How do children born into these families fare?
4. How do policies and environmental conditions affect families and children?

The FFCWS consists of interviews with mothers, fathers, and/or primary caregivers at birth and again when children are ages 1, 3, 5, 9, 15, and 22. The parent interviews collected information on attitudes, relationships, parenting behavior, demographic characteristics, health (mental and physical), economic and employment status, neighborhood characteristics, and program participation. Beginning at age 9, children were interviewed directly (either during the home visit or on the telephone). The direct child interviews collected data on family relationships, home routines, schools, peers, and physical and mental health, as well as health behaviors.

A collaborative study of the FFCWS, the In-Home Longitudinal Study of Pre-School Aged Children (In-Home Study) collected data from a subset of the FFCWS Core respondents at the Year 3 and 5 follow-ups to ask how parental resources in the form of parental presence or absence, time, and money influence children under the age of 5. The In-Home Study collected information on a variety of domains of the child's environment, including: the physical environment (quality of housing, nutrition and food security, health care, adequacy of clothing and supervision) and parenting (parental discipline, parental attachment, and cognitive stimulation). In addition, the In-Home Study also collected information on several important child outcomes, including anthropometrics, child behaviors, and cognitive ability. This information was collected through interviews with the child's primary caregiver, and direct observation of the child's home environment and the child's interactions with his or her caregiver.

Similar activities were conducted during the Year 9 follow-up. At the Year 15 follow-up, a condensed set of home visit activities were conducted with a subsample of approximately 1,000 teens. Teens who participated in the In-Home Study were also invited to participate in a Sleep Study and were asked to wear an accelerometer on their non-dominant wrist for seven consecutive days to track their sleep (Sleep Actigraphy Data) and that day's behaviors and mood (Daily Sleep Actigraphy and Diary Survey Data).

An additional collaborative study collected data from the child care provider (Year 3) and teacher (Years 9 and 15) through mail-based surveys. Saliva samples were collected at Year 9 and 15 (Biomarker file and Polygenic Scores). The Study of Adolescent Neural Development (SAND) COVID Study began data collection in May 2020 following the onset of the COVID-19 pandemic. It included online surveys with the young adult and their primary caregiver.

The FFCWS began its seventh wave of data collection in October 2020, around the focal child's 22nd birthday. Data collection and interviews continued through January 2024. The Year 22 wave included a young adult (YA) survey with the original focal child and a primary caregiver (PCG) survey. Data were also collected on the children of the original focal child (referred to as Generation 3, or G3).

In 2017, the FFCWS team announced the Fragile Families (FF) Challenge, a collaborative effort in which participants were tasked with using machine learning methods and FFCWS data (Baseline to Year 9) to build a model that would predict six key outcomes at Year 15. Materials used in the FF Challenge have been archived in this collection.

In 1999, the Bill and Melinda Gates foundation started the Gates Millennium Scholars Program (GMS), a 20-year initiative which intends to expand access to higher education for high achieving, low-income minority students. In addition to its academic objectives, GMS also has the goal of creating future leaders in minority groups. The program is administered by the United Negro College Fund (UNCF). Awardees can receive the scholarship for up to 5 years as an undergraduate and 4 years as a graduate student. The scholarship is renewable through graduate school in math, science, engineering, library science, and education.

In order to see how GMS has impacted students and to know how to better prepare minority students for college, the Bill and Melinda Gates Foundation has commissioned a survey of recipients. Cohorts are composed of both recipients and non-recipients. Non-recipients are defined as individuals who were asked to go on to the scholar confirmation/verification phase, but did not become a scholar for one or more reasons.

For the first year of the program, GMS awarded 4,053 scholarships to freshman, continuing undergraduate students, and graduate students. Baseline, first follow-up, second follow-up, and longitudinal survey data have been collected from both recipients and non-recipients. Freshmen constitute one respondent type and continuing undergraduate and graduate students comprise a second respondent type.

The Generations study is a five-year study designed to examine health and well-being across three generations of lesbians, gay men, and bisexuals (LGB). The study explored identity, stress, health outcomes, and health care and services utilization among LGBs in three generations of adults who came of age during different historical contexts. This collection includes baseline, wave 1, and wave 2 data collected as part of the Generations study.

The study aimed to assess whether younger cohorts of LGBs differed from older cohorts in how they viewed their LGB identity and experienced stress related to prejudice and everyday forms of discrimination, as well as whether patterns of resilience differed between different LGB cohorts. Additionally, the study sought to examine how differences in stress experience affected mental health and well-being, including depressive and anxiety symptoms, substance and alcohol use, suicide ideation and behavior, and how younger LGBs utilized LGB-oriented social and health services, relative to older cohorts.

In wave 2, respondents were re-interviewed approximately one year after completion of the baseline (wave 1) survey. Only respondents who participated in the original sample of participants were surveyed at wave 2 (i.e., the enhancement oversample was not included in the longitudinal design of this study).

In wave 3, respondents were re-interviewed approximately one year after the completion of the wave 2 survey.

Demographic variables collected as part of this study include questions related to age, education, race, ethnicity, sexual identity, gender identity, income, employment, and religiosity.

The Health and Life Study of Koreans (HLSK) was conducted as a part of the study, "Empirical Assessment of Respondent Driven Sampling from Total Survey Error Perspectives" supported by the National Science Foundation. The larger study aimed to examine the operational and inferential properties of respondent driven sampling (RDS). HLSK applied RDS using a web survey, to examine the health of foreign-born Korean-American adults living in Los Angeles County or the State of Michigan. It should be noted that the literature on analysis of RDS data is not fully established, and there is less than clear empirical evidence illustrating the fit of using RDS for population-level inferences. Hence, data users are advised to exercise extreme caution in making population-level inferences.

This study uses existing questions from established surveys such as the American Community Survey (ACS), Kessler survey of psychological distress, and the California Health Interview Survey (CHIS). The Main Survey covers topics like socio-demographics, physical and mental health, healthcare utilization, religiosity, political engagement, psychosocial traits, and racial/ethnic identity. The Follow-up Survey and Restricted Data focuses on RDS sampling questions and allows users to examine the relationships between recruiters and their recruits. Additionally, the Follow-up Survey and Restricted Data includes variables that contain sensitive information such as multi-racial identity, citizenship status, and physical health characteristics.

The Ithaka S+R Library Survey 2022 examines strategy and leadership issues from the perspective of library deans and directors at not-for-profit four-year academic institutions across the United States. Respondents were asked about their strategies related to services, collections, diversity, equity, inclusion, and accessibility (DEIA), budget, and personnel, their leadership roles within and outside of the library, and their vision for the role of the library. Demographic variables include respondents' number of years in their position, respondents' age, race/ethnicity, and Carnegie Classification.

The Longitudinal Study of American Youth (LSAY) is a project that was funded by the National Science Foundation in 1985 and was designed to examine the development of: (1) student attitudes toward and achievement in science, (2) student attitudes toward and achievement in mathematics, and (3) student interest in and plans for a career in science, mathematics, or engineering, during middle school, high school, and the first four years post-high school. The relative influence parents, home, teachers, school, peers, media, and selected informal learning experiences had on these developmental patterns was considered as well.

The older LSAY cohort, Cohort One, consisted of a national sample of 2,829 tenth-grade students in public high schools throughout the United States. These students were followed for an initial period of seven years, ending four years after high school in 1994. Cohort Two, consisted of a national sample of 3,116 seventh-grade students in public schools that served as feeder schools to the same high schools in which the older cohort was enrolled. These students were followed for an initial period of seven years, concluding with a telephone interview approximately one year after the end of high school in 1994.

Beginning in the fall of 1987, the LSAY collected a wide array of information including: (1) a science achievement test and a mathematics achievement test each fall, (2) an attitudinal and experience questionnaire at the beginning and end of each school year, (3) reports about education and experience from all science and math teachers in each school, (4) reports on classroom practice by each science and math teacher serving a LSAY student, (5) an annual 25-minute telephone interview with one parent of each student, and (6) extensive school-level information from the principal of each study school.

In 2006, the NSF funded a proposal to re-contact the original LSAY students (then in their mid-30's) to resume data collection to determine their educational and occupational outcomes. Through an extensive tracking activity which involved: (1) online tracking, (2) newsletter mailing, (3) calls to parents and other relatives, (4) use of alternative online search methods, and (5) questionnaire mailing, more than 95 percent of the original sample of 5,945 LSAY students were located or accounted for. In addition to re-contacting the students, the proposal defined a new eligible sample of approximately 5,000 students and these young adults were asked to complete a survey in 2007. A second survey was conducted in the fall of 2008 that sought to gather updated information about occupational and education outcomes and to measure the civic scientific literacy of these young adults, in which to date more than 3,200 participants have responded. A third survey was conducted in the fall of 2009 that sought to gather updated information about occupational and education outcomes and to measure the participants' use of selected informal science education resources, in which to date more than 3,200 participants have responded. A fourth survey was conducted in the fall of 2010 that sought to gather updated information about occupational and education outcomes, as well as provided questions about the participants' interactions with their children, in which to date more than 3,200 participants have responded. Finally, a fifth survey was conducted in the fall of 2011 that sought to gather updated information about education outcomes and included an expanded occupation battery for all participants, as well as an expanded spousal information battery for all participants. The 2011 questionnaire also included items about the 2011 Fukushima incident in Japan along with attitudinal items about nuclear power and global climate change. To date approximately 3,200 participants responded to the 2011 survey.

There were no surveys conducted in 2012 or 2013. Beginning in 2014 the LSAY was funded by the National Institute on Aging for five years. This data release adds the 2017 data to the previous data release that included data through 2016.

The public release data files include information collected from the national probability sample students, their parents, and the science and mathematics teachers in the students' schools. The data covers the initial seven years, beginning in the fall of 1987, as well as the data collected in the 2007, 2008, 2009, 2010, 2011, 2014, 2015, 2016, and 2017 questionnaires.

Part 1: LSAY Merged Cohort (Base File) contains student and parent data from both cohorts of the LSAY from 1987-1994 and student follow-up data from 2007-2011 and 2014-2017. Additionally, Parts 2 - 5 contain information gathered from two teacher background questionnaires and two principal questionnaires from 1987-1994.

The Longitudinal Study of American Youth (LSAY) is a project that was originally funded by the National Science Foundation in 1985 and was designed to examine the development of: (1) student attitudes toward and achievement in science, (2) student attitudes toward and achievement in mathematics, and (3) student interest in and plans for a career in science, mathematics, or engineering, during middle school, high school, and the first four years post-high school. The relative influence parents, home, teachers, school, peers, media, and selected informal learning experiences had on these developmental patterns was considered as well.

The LSAY was designed to select and follow two cohorts of students in 1987. Cohort One was a national sample of approximately 3,000 tenth grade students in public high schools throughout the United States. Cohort Two, consisted of a national sample of 3,116 seventh grade students in public schools that served as feeder schools to the same high schools in which the older cohort was enrolled. Data collection continues for Cohorts One and Two, 31 years after the study began.

In the fall of 2015, data collection began on a third cohort: Cohort Three. Cohort Three consisted of 3,721 students in the seventh grade in public schools throughout the United States. The data in this release provides seventh grade comparison data across a 28-year timespan: Cohort Two (1987-1988) and Cohort Three (2015-2016).

This study includes arts-related variables about student and parent participation in music, art, literary, dance, and theatrical pursuits. For a more details please see Description of Variables.

This study focuses on understanding how the National Memorial for Peace and Justice (NMPJ), the first large-scale memorial to black or African American victims of lynching, affects the immediate community surrounding it. Memorialization in the United States has been a growing trend over the past few decades. To date, there has been limited research on how memorials affect relationships between groups and how they impact the attitudes and behaviors of individuals. This study explores how the representation of past racial violence is interpreted and responded to by those who regularly interact with it. The study helps to understand better how the practice of memorialization mediates how our nation grapples with the darkest moments of its past.

The data include the following:

• Survey data: A four-wave longitudinal survey of the local city's residents was conducted pre- and post NMPJ's opening to capture social and political attitudes. Additionally, a two-wave longitudinal survey was conducted with two comparison groups in Alabama
• Secondary data: Montgomery City Police Department crime data concerning reported incidents that occurred between Oct. 27, 2017 and Oct. 31, 2018. The collection was restricted to incidents that occurred within two miles of NMPJ
• Secondary data: Links to and metadata of 619 American media stories in English addressing NMPJ, which were published between Aug. 16, 2016 and Jan. 17, 2020

This survey of 12th-grade students is part of a series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth. Students are randomly assigned to complete one of six questionnaires, each with a different subset of topical questions, but all containing a set of "core" questions on demographics and drug use. There are about 1,400 variables across the questionnaires. Drugs covered by this survey include tobacco, smokeless tobacco, alcohol, marijuana, hashish, prescription medications, over-the-counter medications, LSD, hallucinogens, amphetamines (stimulants), Ritalin (methylphenidate), Quaaludes (methaqualone), barbiturates (tranquilizers), cocaine, crack cocaine, GHB (gamma hydroxy butyrate), ecstasy, methamphetamine, and heroin. Other topics include attitudes toward religion, changing roles for women, educational aspirations, self-esteem, exposure to drug education, and violence and crime (both in and out of school).

The National Institute on Drug Abuse (NIDA) funded RADAR in 2014 to collect multilevel, longitudinal data and biospecimens from an ethnically and racially diverse cohort of young, sexual and gender minorities (SGM; e.g., men who have sex with men (MSM), transgender women, gender non-conforming individuals) who were assigned male at birth (AMAB) (current core cohort n=1,113). The primary objective of this study is to apply a multilevel perspective to a syndemic of health issues associated with human immunodeficiency virus (HIV) in this population. The multilevel design focuses on individual, dyadic (i.e., sexual and romantic relationships), network (i.e., social, drug, and sexual connections) and biologic factors that may be associated with HIV. The cohort contains both HIV-negative and HIV-positive individuals, which allows for the development of a repository of biospecimens and HIV sequence data from both pre-infection and post-infection visits that will help facilitate future projects evaluating substance use, HIV risk, and pathogenesis.

A multiple cohort, accelerated longitudinal design was utilized by initially enrolling two existing SGM cohorts and then expanded through the use of convenience and snowball sampling methods. Enrollment criteria varied slightly based on the recruitment method, but overall inclusion criteria required participants to be AMAB, between 16 and 29 years of age, report having had sex with a man in the prior year or identify as a SGM, live in the Chicago metropolitan area, and be an English speaker. Study recruitment opened in February 2015. Participants are followed through the developmental period of late adolescence to early adulthood, which is a critical period of initiation and acceleration of sexual behavior and substance use. Study visits occur every six months.

The National Survey of Substance Abuse Treatment Services (N-SSATS) is designed to collect information from all facilities in the United States, both public and private, that provide substance abuse treatment. N-SSATS provides the mechanism for quantifying the dynamic character and composition of the United States substance abuse treatment delivery system. The objectives of N-SSATS are to collect multipurpose data that can be used to assist the Substance Abuse and Mental Health Services Administration (SAMHSA) and state and local governments in assessing the nature and extent of services provided and in forecasting treatment resource requirements, update SAMHSA's Inventory of Substance Abuse Treatment Services (I-SATS), analyze general treatment services trends, and generate the National Directory of Drug and Alcohol Abuse Treatment Programs and its online equivalent, the Substance Abuse Treatment Facility Locator.

Data are collected on topics including facility operation, services offered (assessment, substance abuse therapy and counseling, testing, transitional, and ancillary), primary focus (substance abuse, mental health, both, general health, other), hotline operation, Opioid Treatment Programs and medication dispensed, languages in which treatment is provided, type of treatment provided, number of clients (total and under age 18), number of beds, types of payment accepted, sliding fee scale, special programs offered, facility accreditation and licensure/certification, and managed care agreements.

Data are collected on topics including facility operation, services offered (assessment, substance abuse therapy and counseling, pharmacotherapies, testing, transitional, ancillary), primary focus (substance abuse, mental health, both, general health, other), hotline operation, Opioid Treatment Programs and medication dispensed, languages in which treatment is provided, type of treatment provided, number of clients (total and under age 18), number of beds, types of payment accepted, sliding fee scale, special programs offered, facility accreditation and licensure/certification, and managed care agreements.

The National Survey of Substance Abuse Treatment Services (N-SSATS) is designed to collect information from all facilities in the United States, both public and private, that provide substance abuse treatment.

This study brings to light what is both patently obvious and far too often dismissed from the human rights agenda. Transgender and gender non-conforming people face injustice at every turn: in childhood homes, in school systems that promise to shelter and educate, in harsh and exclusionary workplaces, at the grocery store, the hotel front desk, in doctors' offices and emergency rooms, before judges and at the hands of landlords, police officers, health care workers and other service providers.

The National Gay and Lesbian Task Force and the National Center for Transgender Equality are grateful to each of the 6,450 transgender and gender non-conforming study participants who took the time and energy to answer questions about the depth and breadth of injustice in their lives. A diverse set of people, from all 50 states, the District of Columbia, Puerto Rico, Guam and the U.S. Virgin Islands, completed online or paper surveys. This tremendous gift has created the first 360-degree picture of discrimination against transgender and gender non-conforming people in the U.S. and provides critical data points for policymakers, community activists and legal advocates to confront the appalling realities documented here and press the case for equity and justice.

These data provide information on discrimination in every major area of life, including housing, employment, health and health care, education, public accommodation, family life, criminal justice and government identity documents, and demographic information such as citizenship, race, ethnicity, employment, and income. In virtually every setting, the data underscores the urgent need for policymakers and community leaders to change their business-as-usual approach and confront the devastating consequences of anti-transgender bias.

Demographic information includes race, ethnicity, gender identity, sexual orientation, education, income, U.S citizenship, household size, and relationship status.

The public-use dataset was created in an earlier version of Stata that truncated write-in responses after 244 characters. The non-truncated write-in responses, plus Q10 zip codes and the essay responses to Q70, are included in the restricted-use dataset.

The goals of this study were to test whether participants who engaged in an extreme ritual in a naturalistic setting would evidence signs of altered states of consciousness, to examine other physiological and affective effects of the ritual, and to determine whether these effects varied based on the role the individual performed within the ritual. A multi-method approach was used that utilized various psychological self-report measures, a measure of cognitive functioning, and a measure of physiological stress. The data collection took place at the "Dance of Souls," a ritual conducted on the last day of the annual Southwest Leather Conference in Phoenix, Arizona, in which participants received temporary piercings with hooks or weights attached to the piercings and danced to music provided by drummers.

The associated publication, Altered States of Consciousness during an Extreme Ritual, was used to accompany the data in this collection. Users are encouraged to consult the publication for additional information. The data collection includes one de-identified dataset with 164 variables for 83 cases. Demographic variables include sex, gender, pierced vs. non-pierced, and the role the participant played in the ceremony.

The Social Justice Sexuality Project (SJS) is one of the largest national surveys of Black, Latina/o, Asian and Pacific Islander, and multiracial lesbian, gay, bisexual, and transgender (LGBT) people. With over 5,000 respondents, the final sample includes respondents from all 50 states; Washington, DC, and Puerto Rico; in rural and suburban areas, in addition to large urban areas; and from a variety of ages, racial/ethnic identities, sexual orientations, and gender identities. The purpose of the SJS Project is to document and celebrate the experiences of lesbian, gay, bisexual and transgender (LGBT) people of color. All too often, when we think about LGBT people of color, it's from a perspective of pathology. In contrast, the SJS Project is designed and dedicated to describing a more dynamic experience. It's a knowledge-based study that investigates the sociopolitical experiences of this population around five themes: racial and sexual identity; spirituality and religion; mental and physical health; family formations and dynamics; civic and community engagement. Demographic variables include: race/ethnicity, sexual orientation, gender identity, age, education, religion, household, income, height, weight, location, birthplace, and political affiliation.

Since 2007, the American Psychological Association (APA) has commissioned an annual nationwide survey as part of its Mind/Body Health campaign to examine the state of stress across the country and understand its impact. The Stress in America survey measures attitudes and perceptions of stress among the general public and identifies leading sources of stress, common behaviors used to manage stress and the impact of stress on our lives. The results of the survey draw attention to the serious physical and emotional implications of stress and the inextricable link between the mind and body.

From 2007 to 2024, the research has documented this connection among the general public as well as various sub-segments of the public. Each year, the Stress in America surveys aims to uncover different aspects of the stress/health connection via focusing on a particular topic and/or subgroup of the population. Below is a list of the focus of each of the Stress in America surveys.

This study is a continuation of an ongoing 40+ year surveillance effort assessing the levels and patterns of substance use among American Indian (AI) adolescents attending schools on or near reservations. The current set of data is from the most recent funding cycle, 2015-2020. During this funding cycle, annual samples across various geographic regions in which reservation-based AI residents reside were obtained and school-based surveys were completed. In addition to the annual epidemiology of substance use, data pertaining to risk and protective factors, including cultural-ethnic identity, perceived discrimination, family factors, and individual risk and protective factors were obtained. It should be noted that two major changes were made during this funding cycle:

1) The wording of substance use variables was altered to mirror wording from Monitoring the Future to allow for direct comparisons between the two studies.

2) All data during this funding cycle were obtained online using Qualtrics.

The TransPop study is the first national probability sample of transgender individuals in the United States (it also includes a comparative cisgender sample). A primary goal of this study was to provide researchers with a representative sample of transgender people in the United States. The study examines a variety of health-relevant domains including health outcomes and health behaviors, experiences with interpersonal and institutional discrimination, identity, transition-related experiences, and basic demographic characteristics (age, race/ethnicity, religion, political party affiliation, marital status, employment, income, location, sex, gender, and education).

Co-investigators (in alphabetical order): Walter O. Bockting, Ph.D. (Columbia University); Jody L. Herman, Ph.D. (UCLA); Sari L. Reisner, Ph.D. (Harvard University and The Fenway Institute, Fenway Health).

This data collection contains the results of a follow-up cross-sectional study to the 2016 assessment of the current campus climate with respect to diversity, equity, and inclusion. The sample survey of the University of Michigan (U-M), Ann Arbor, faculty, staff, and students was meant to represent the full diversity of the community and to capture information and perceptions on demographics, climate, institutional commitment and inclusive and equitable treatment, departmental norms, intergroup interactions, and discrimination. With input from committees of students, faculty, and staff, the survey instrument was developed collaboratively by the U-M Office of the Provost, U-M's Survey Research Center, and administered by SoundRocket, an external social science survey research company. The instrument was delivered as a web survey, and several notifications and reminders were used to encourage completion, as well as an incentive. These notifications and reminders were delivered in phases.

Variables in the collection describe age, gender and gender identity, race/ethnicity, school/department/unit, religious affiliation, disability status, campus safety, rating of campus climate, intergroup interaction, discriminatory events, composite rating scores, and more.
