The American Community Survey (ACS) is a part of the Decennial Census Program, and is designed to produce critical information about the characteristics of local communities. The ACS publishes social, housing, and economic characteristics for demographic groups covering a broad spectrum of geographic areas in the United States and Puerto Rico. Every year the ACS supports the release of single-year estimates for geographic areas with populations of 65,000 or more. Demographic variables include sex, age, relationship, households by type, race, and Hispanic origin. Social characteristics variables include school enrollment, educational attainment, marital status, fertility, grandparents caring for children, veteran status, disability status, residence one year ago, place of birth, United States citizenship status, year of entry, world region of birth of foreign born, language spoken at home, and ancestry. Variables focusing on economic characteristics include employment status, commuting to work, occupation, industry, class of worker, income and benefits, and poverty status. Variables focusing on housing characteristics include occupancy, units in structure, year structure was built, number of rooms, number of bedrooms, housing tenure, year householder moved into unit, vehicles available, house heating fuel, utility costs, occupants per room, housing value, and mortgage status. The American Community Survey is conducted under the authority of Title 13, United States Code, Sections 141 and 193, and response is mandatory.

Early Intervention Colorado (EI-CO) Participant Characteristics, Service Use, and Outcomes, Colorado, 2014-2016 (ICPSR 37131)

Released/updated on: 2018-09-05
Geographic coverage: United States, Colorado
Time period: 2014-10-01--2016-09-01

Part C of the Individuals with Disabilities Education Act authorizes states, with the incentive of federal financial support, to create Early Intervention (EI) systems, which is a primary source of rehabilitation (e.g., physical, occupational, and speech therapy) services for infants and toddlers with, or at risk for, developmental delays. Having worked with two EI Colorado (EI-CO) programs that employed electronic documentation, the researchers sought to leverage their electronic administrative data in order to examine social disparities in EI service use, including specific rehabilitation services.

The dataset for this data archiving project was generated in collaboration with a large, urban EI program in Colorado, a community partner for an NIH/NCMRR R03 study. This academic-community research partnership provided researchers with access to an urban EI program's electronic administrative database; The researchers' goal was to make these data available for further EI research. Therefore, a database was created and a number of variables were derived that could be of importance to EI stakeholders when conducting clinical queries for quality improvement. Examples of derived variables include EI service use intensity (i.e., hours per month) for all EI services, as well as discipline-specific (e.g., physical or occupational therapy) service use. The researchers obtained permission from the partnering EI agency to archive their EI program data through this project.

The dataset included as part of this collection includes 2045 cases for 44 variables; demographic variables include: race, ethnicity, language, sex, age, and developmental condition type.

Early Intervention Colorado (EI-CO) Participant Characteristics, Service Use, and Patient-Reported Outcomes, Colorado, 2017-2021 (ICPSR 37320)

Released/updated on: 2023-11-28
Geographic coverage: United States, Colorado
Time period: 2017-01-01--2021-01-01

The Individuals with Disabilities Education Act authorizes states to create early intervention (EI) programming to provide developmental and therapeutic services to infants and toddlers with a developmental condition; EI programs are mandated to report on child and family outcomes for purposes of accountability and quality improvement. For both purposes, there is critical need for research evidence on the adequacy of EI services. The researchers for this study partnered with a large urban EI program in Colorado that had recently transitioned to electronic data capture and was implementing a statewide initiative to facilitate function-focused care with individual families and paired collected electronic patient-reported outcomes (e-PRO) data with EI administrative data on child and family characteristics and service use to more fully examine EI service adequacy relative to patient-important outcomes.

This study collected information from Young Children's Participation and Environment Measure (YC-PEM e-PRO) on home, environment, and community participation, involvement, and desired change. Measurements were also collected from the Pediatric Evaluation of Disability Inventory Computer Adaptive Test (PEDI-CAT e-PRO) on mobility, social cognitive, and daily activities domains. The Child Outcomes Summary (COS) was used to capture functional performance related to having positive social relationships, acquiring and using knowledge and skills, and taking appropriate action to meet needs. Early Intervention Service Use measured EI intensity, whether child received specific services including physical therapy (PT), occupational therapy (OT), speech therapy (ST), psychology, or developmental intervention (DI), and the total number of service hours received within each discipline. Demographic variables include reasons child received EI services, number of developmental delay conditions, age, race, and ethnicity; as well as caregiver's education, employment, number of children at home, income, and insurance type.

Evaluation of Boot Camps for Juvenile Offenders in Cleveland, Denver, and Mobile, 1992-1993 (ICPSR 6922)

Released/updated on: 2006-03-30
Geographic coverage: United States, Colorado, Ohio, Denver, Alabama, Cleveland, Mobile
Time period: 1992-01-01--1993-01-01
Boot camps, a popular alternative to standard correctional facilities, are characterized by a strong emphasis on military structure, drill, and discipline and by an abbreviated period of incarceration. In 1990, the Office of Juvenile Justice and Delinquency Prevention (OJJDP) launched a demonstration program to develop boot camp models for juveniles and to test the feasibility and appropriateness of their implementation. In September 1991, three groups received awards to develop and implement boot camps as intermediate sanctions: the Cuyahoga County Court of Common Pleas in Cleveland, Ohio, the Colorado Division of Youth Services in Denver, Colorado, and the Boys and Girls Clubs of Greater Mobile, Alabama. Simultaneously, the National Institute of Justice sponsored an evaluation of the implementation of the demonstration programs, focusing on the experiences of youths who entered the program during the first year of operation, from 1992 to 1993. This collection contains data from the program evaluation conducted on these three boot camps during the first year. The core of the assessment was a management information system that captured administrative data as the offenders progressed through the demonstration program. At intake, researchers collected demographic, criminal, and family and social information. Demographic information collected at intake includes age, race, education, and employment. Criminal data covers criminal history, current offense, and case information, while family and social history variables include whether the youths' parents had a criminal record, whether their family received public assistance, and whether they had delinquent friends, delinquent siblings, discipline problems at home or school, or a history of psychological problems. At the beginning and end of the boot camp term, staff rated the youths' performance on educational and behavioral measures. The youths were also surveyed about the rules of boot camp, their opinions of instructors, and their self-esteem, drug and alcohol use, and criminal behavior. At the end of the first 90 days (the residential period), data were collected on the date of graduation, infractions during boot camp, honors or awards, and special services received. Five months after graduation, youths were evaluated on their aftercare experiences. Some sites supplemented the basic management information with data collected on educational performance, employment history and expectations, physical fitness, and youth attitudes.

Great Plains Population and Environment Data: Agricultural Data, 1870-1997 [United States] (ICPSR 4254)

Released/updated on: 2005-06-22
Geographic coverage: Montana, United States, Wyoming, Oklahoma, South Dakota, Minnesota, Kansas, Nebraska, Iowa, New Mexico, Texas, Colorado, North Dakota
Time period: 1870-01-01--1997-01-01
The data in this series of studies were assembled by an interdisciplinary research team led by Myron Gutmann of the University of Michigan between 1995 and 2004, as part of a research project funded by the National Institute of Child Health and Human Development (Grant Number R01HD033554 to the University of Michigan). The goal of the project was to amass information about approximately 500 counties in 12 states of the Great Plains of the United States, and then to analyze those data in order to understand the relationships between population and environment that existed between the years of about 1870 and 2000. The data distributed here are all data about counties. They fall into four broad categories: about the counties, about agriculture, about demographic and social conditions, and about the environment. The information about counties (name, area, identification code, and whether the project classified the county as part of the Great Plains in a given year) is embedded in each of the other data files, so that there will be three series of data (agriculture, demographic and social conditions, and environment), containing individual data files for each year for which data are available. The United States Census of Agriculture has been conducted since 1850 on a regular schedule that was decennial until 1920, and more frequently thereafter (every five years from 1925 to 1950, then in 1954, 1959, 1964, 1978, and every five years since 1982). The agricultural data included in this collection consist of a single data file for each agricultural census year between 1870 and 1997 that includes selected material compiled as part of the United States Agricultural Census. The county-level agricultural data produced by the United States government as part of the census constitute a consistent series of measures of changing agriculture and land use.

Great Plains Population and Environment Data: Social and Demographic Data, 1870-2000 [United States] (ICPSR 4296)

Released/updated on: 2007-02-07
Geographic coverage: Montana, United States, Wyoming, New Mexico, Oklahoma, Texas, Colorado, South Dakota, Kansas, North Dakota, Nebraska
Time period: 1870-01-01--2000-01-01

The social and demographic data included in this collection consist of a single data file for each decennial year between 1870 and 2000, covering 10 of the 12 Great Plains states. Information on a variety of social and demographic topics was gathered to historically characterize populations living in counties within the United States Great Plains, in terms of: (1) urban, rural, and total population, (2) vital statistics, (3) net migration, (4) age and sex, (5) nativity and ancestry, (6) education and literacy, (7) religion, (8) industry, and (9) housing and other characteristics. These data include selected material compiled as part of the United States population census. The United States Census of Population and Housing has been conducted since 1790 on a regular schedule that is decennial. The county-level social and demographic data produced by the United States government as a result constitute a consistent series of measures capturing changes in the United States population's size, composition, and other characteristics. A subset of the variables available from the short and long-form survey questionnaires of the United States Census of Population and Housing (as compiled for counties) were extracted from previously existing digital files. Besides the decennial census of the population, county-level data were drawn from an assortment of existing digital files as well as sources that were manually digitized. Other data include compilations of county-level information gathered from various federal agencies and private organizations as well as the agriculture and economic censuses. Supplementing these compilations are manually digitized consumer market data, religious data, and vital statistics, including information about births, deaths, marriage, and divorce.

Helping Young Smokers Quit: Identifying Best Practices for Tobacco Cessation, Phase II National Program Evaluation, 2003-2006 (ICPSR 33161)

Released/updated on: 2024-02-14
Geographic coverage: Oregon, New York, United States, Kentucky, Minnesota, California, Utah, Washington, Michigan, Iowa, Illinois, Texas, Colorado, Missouri, Louisiana, Ohio, Maryland, Wisconsin, Nevada
Time period: 2003-01-01--2006-01-01

The Helping Young Smokers Quit (HYSQ) initiative was a multi-phase project that addressed the critical need to disseminate effective, developmentally appropriate cessation programs for young smokers. Phase I identified and described tobacco treatment programs available for youth in the United States, Phase II evaluated smoking secession programs tailored for youth to help understand what works, and Phase III identified factors associated with program sustainability. Phase II collected data from five sources: (1) program participants, (2) program providers, (3) program curricula, (4) organizational leaders, and (5) community leaders and community ordinances.

Program participants were interviewed at baseline, end-of program, 6-month follow-up, and 12-month follow-up. Topics covered by the interviews include age, gender, race, Hispanic origin, language spoken at home, employment, income, religiosity, school enrollment, education level, school grades, height, weight, extracurricular activities, recreation, sports, exercise, aspirations after high school, psychological well-being, alcohol consumption, cigarette use and use of other tobacco products, attitudes about smoking, plans to stop/continue smoking, attempts to quit smoking, reasons for participating in the program, topics/issues covered by the program, opinions about the program, and smoking experience since the beginning of the program. In addition, for each follow-up survey, the participants provided a breath sample for carbon monoxide analysis to validate self-reported quit status.

After the last session of each program delivery, the program providers, such as program leaders and cessation counselors, were interviewed about the content and delivery of the program and the reactions of the participants and themselves to the program as delivered. The program providers also kept attendance records.

Curriculum content was abstracted from program manuals and other materials used in each program.

Organizational leaders of the organizations that offered the programs were surveyed about various aspects of each organization, including the organization's smoking cessation program and the organization's mission, general operations, and smoking-related policies and practices.

Community-level information was collected in two ways: (1) interviews of community leaders representing local health departments, school boards, and juvenile justice offices, and (2) archival research of public ordinances relevant to tobacco and control policies.

Nine data files/datasets constitute the data. Datasets 1-4 contain the participant questionnaire data, carbon monoxide measurement data, and program attendance data. Dataset 5 comprises information about each program and its curriculum, some information about the community in which the program was located, and summary data about enforcement of tobacco-related ordinances. Dataset 6 contains information about about the program providers and each program delivery, including recruitment, logistics, content, and the reactions of providers and participants. Dataset 7 covers administrative aspects of the smoking cessation programs and each offering organization's mission, general operations, and smoking-related policies and norms. Dataset 8 contains information about local and state-level tobacco-related ordinances for every state and local jurisdiction where each program was located, and Dataset 9 condenses the information in Dataset 8 into one summary record for each community. The unit of observation for Datasets 1-4 is the participant, for Datasets 5 and 7 the smoking cessation program/offering organization, for Dataset 6 the program delivery/program cohort, for Dataset 8 the ordinance, and for Dataset 9 the community.

Hispanic Established Populations for Epidemiologic Studies of the Elderly (EPESE) Frailty Study: 2006-2009 (ICPSR 36321)

Released/updated on: 2016-03-29
Geographic coverage: United States, New Mexico, Texas, Colorado, California, Arizona
Time period: 2006-01-01--2009-01-01
The Hispanic Established Populations for Epidemiologic Studies of the Elderly (EPESE) Frailty Study sought to apply a standard definition of frailty in a well-defined sample of Mexican American older adults and to examine the impact of frailty on disability, health related quality of life, institutionalization, and mortality in this population over time. This project is a continuation of a prior study (the Hispanic EPESE) examining the enabling-disabling process in this same population of aging Mexican Americans; data were collected from 1,031 older adults who were participating in the Hispanic EPESE. Only subjects who were physically capable of safely completing the muscle strength measures were included. Baseline interviews were collected for this subsample in 2006/2007 during Wave 6 (ICPSR 29654) of the Hispanic EPESE study. This collection includes data about respondents' health status, activities of daily living and their ability to perform tasks. Two-year follow-up data were collected in 2008/2009 from 731 participants in Wave 1. Demographic and background information include age, relationship status, gender, marital status and household composition.

The baseline Hispanic Established Populations for the Epidemiologic Studies of the Elderly (Hispanic EPESE, ICPSR 2851) was modeled after the design of ESTABLISHED POPULATIONS FOR EPIDEMIOLOGIC STUDIES OF THE ELDERLY, 1981-1993: [EAST BOSTON, MASSACHUSETTS, IOWA AND WASHINGTON COUNTIES, IOWA, NEW HAVEN, CONNECTICUT, AND NORTH CENTRAL NORTH CAROLINA] (ICPSR 9915) and ESTABLISHED POPULATIONS FOR EPIDEMIOLOGIC STUDIES OF THE ELDERLY, 1996-1997: PIEDMONT HEALTH SURVEY OF THE ELDERLY, FOURTH IN-PERSON SURVEY [DURHAM, WARREN, VANCE, GRANVILLE, AND FRANKLIN COUNTIES, NORTH CAROLINA] (ICPSR 2744). This data collection contains the two-year follow-up of the baseline Hispanic EPESE, which collected data on a representative sample of community-dwelling Mexican-American elderly, aged 65 years and older, residing in the five southwestern states of Arizona, California, Colorado, New Mexico, and Texas. The primary purpose of the study was to provide estimates of the prevalence of key physical health conditions, mental health conditions, and functional impairments in older Mexican Americans and to compare these estimates with those for other populations. The Hispanic EPESE attempted to determine whether certain risk factors for mortality and morbidity operate differently in Mexican Americans than in non-Hispanic White Americans, African Americans, and other major ethnic groups. The public-use data cover demographic characteristics (age, sex, type of Hispanic race, income, education, marital status, number of children, employment, and religion), height, weight, social and physical functioning, chronic conditions, related health problems, health habits, self-reported use of dental, hospital, and nursing home services, and depression. This two-year follow-up is a cross-sectional examination of the predictors of mortality, changes in health outcomes, institutionalization, and other changes in living arrangements, as well as changes in life situations and quality of life issues. The Medications file (Part 2) includes a listing of the medications, by brand name and classification of the drug, which were prescribed for the respondent. The vital status of respondents from baseline to this round of the survey may be determined using the Vital Status file (Part 3). This file contains interview dates from the baseline as well as vital status at Wave II (respondent survived, date of death if deceased, proxy-assisted, proxy-true).

The Hispanic EPESE collected data on a representative sample of community-dwelling Mexican-American elderly, aged 65 years and older, residing in the five southwestern states of Arizona, California, Colorado, New Mexico, and Texas. The primary purpose of the series was to provide estimates of the prevalence of key physical health conditions, mental health conditions, and functional impairments in older Mexican Americans and to compare these estimates with those for other populations. The Hispanic EPESE attempted to determine whether certain risk factors for mortality and morbidity operate differently in Mexican Americans than in non-Hispanic White Americans, African Americans, and other major ethnic groups. The public-use data cover background characteristics (age, sex, type of Hispanic race, income, education, marital status, number of children, employment, and religion), height, weight, social and physical functioning, chronic conditions, related health problems, health habits, self-reported use of dental, hospital, and nursing home services, and depression. The follow-ups provide a cross-sectional examination of the predictors of mortality, changes in health outcomes, and institutionalization and other changes in living arrangements, as well as changes in life situations and quality of life issues. The vital status of respondents from baseline to this round of the survey may be determined using the Vital Status file (Part 2). This file contains interview dates from the baseline as well as vital status at Wave IV (respondent survived, date of death if deceased, proxy-assisted, proxy-reported cause of death, proxy-true). The first follow-up of the baseline data (Hispanic EPESE Wave II, 1995-1996 [ICPSR 3385]) followed 2,438 of the original 3,050 respondents, and the second follow-up (Hispanic EPESE Wave III, 1998-1999 [ICPSR 4102]) followed 1,980 of these respondents. Hispanic EPESE, 1993-1994 (ICPSR 2851), was modeled after the design of ESTABLISHED POPULATIONS FOR EPIDEMIOLOGIC STUDIES OF THE ELDERLY, 1981-1993: [EAST BOSTON, MASSACHUSETTS, IOWA AND WASHINGTON COUNTIES, IOWA, NEW HAVEN, CONNECTICUT, AND NORTH CENTRAL NORTH CAROLINA] (ICPSR 9915) and ESTABLISHED POPULATIONS FOR EPIDEMIOLOGIC STUDIES OF THE ELDERLY, 1996-1997: PIEDMONT HEALTH SURVEY OF THE ELDERLY, FOURTH IN-PERSON SURVEY [DURHAM, WARREN, VANCE, GRANVILLE, AND FRANKLIN COUNTIES, NORTH CAROLINA] (ICPSR 2744).

The Hispanic Established Populations for the Epidemiologic Studies of the Elderly (Hispanic EPESE) was modeled after the design of the ESTABLISHED POPULATIONS FOR EPIDEMIOLOGIC STUDIES OF THE ELDERLY, 1981-1993: [EAST BOSTON, MASSACHUSETTS, IOWA AND WASHINGTON COUNTIES, IOWA, NEW HAVEN, CONNECTICUT, AND NORTH CENTRAL NORTH CAROLINA] (ICPSR 9915) and ESTABLISHED POPULATIONS FOR EPIDEMIOLOGIC STUDIES OF THE ELDERLY, 1996-1997: PIEDMONT HEALTH SURVEY OF THE ELDERLY, FOURTH IN-PERSON SURVEY [DURHAM, WARREN, VANCE, GRANVILLE, AND FRANKLIN COUNTIES, NORTH CAROLINA] (ICPSR 2744). The Hispanic EPESE collected baseline data beginning in September 1993 through June 1994 on a representative sample of community-dwelling Mexican-American elderly, aged 65 years and older, residing in the five southwestern states of Arizona, California, Colorado, New Mexico, and Texas. The primary purpose of the study was to provide estimates of the prevalence of key physical health conditions, mental health conditions, and functional impairments in older Mexican Americans and to compare these estimates with those for other populations. The Hispanic EPESE attempted to determine whether certain risk factors for mortality and morbidity operate differently in Mexican Americans than in non-Hispanic White Americans, African Americans, and other major ethnic groups. The public use baseline data cover demographic characteristics (age, sex, type of Hispanic race, income, education, marital status, number of children, employment, and religion), height, weight, social and physical functioning, chronic conditions, related health problems, health habits, self-reported use of dental, hospital, and nursing home services, and depression.

Hispanic Established Populations for the Epidemiologic Study of the Elderly (HEPESE) Wave 5, 2004-2005 [Arizona, California, Colorado, New Mexico, and Texas] (ICPSR 25041)

Released/updated on: 2009-09-23
Geographic coverage: United States, New Mexico, Texas, Colorado, California, Arizona
Time period: 2004-01-01--2005-01-01
This dataset comprises the fourth follow-up of the baseline Hispanic EPESE (HISPANIC ESTABLISHED POPULATIONS FOR THE EPIDEMIOLOGIC STUDIES OF THE ELDERLY, 1993-1994: [ARIZONA, CALIFORNIA, COLORADO, NEW MEXICO, AND TEXAS] [ICPSR 2851]). The baseline Hispanic EPESE collected data on a representative sample of community-dwelling Mexican-Americans, aged 65 years and older, residing in the five southwestern states of Arizona, California, Colorado, New Mexico, and Texas. The primary purpose of the series was to provide estimates of the prevalence of key physical health conditions, mental health conditions, and functional impairments in older Mexican Americans and to compare these estimates with those for other populations. The Hispanic EPESE provides data on risk factors for mortality and morbidity in Mexican Americans in order to contrast how these factors operate differently in non-Hispanic White Americans, African Americans, and other major ethnic groups. The public-use data cover demographic characteristics (age, sex, type of Hispanic race, income, education, marital status, number of children, employment, and religion), height, weight, social and physical functioning, chronic conditions, related health problems, health habits, self-reported use of dental, hospital, and nursing home services, and depression. Subsequent follow-ups provide a cross-sectional examination of the predictors of mortality, changes in health outcomes, and institutionalization, and other changes in living arrangements, as well as changes in life situations and quality of life issues. During this 5th Wave, 2004-2005, reinterviews were conducted either in person or by proxy, with 1,167 of the original respondents. This 4th follow-up includes an additional sample of 902 Mexican Americans aged 75 and over with higher average-levels of education than those of the surviving cohort, increasing the total number of respondents to 2,069. By diversifying the cohort of those aged 75 and older, a better understanding can be gained of the influence of socioeconomic and cultural variations on the lives and health of older Mexican Americans.

Latino National Survey (LNS), 2006 (ICPSR 20862)

Released/updated on: 2013-06-05
Geographic coverage: North Carolina, United States, Fort Worth, Arkansas, Washington, San Diego, Atlanta, Colorado, Denver, Dallas, Arizona, Nevada, New York, District of Columbia, Seattle, San Antonio, Chicago, California, Florida, New Jersey, Miami, Iowa, Illinois, Texas, Los Angeles, Georgia, Houston
The Latino National Survey (LNS) contains 8,634 completed interviews (unweighted) of self-identified Latino/Hispanic residents of the United States. Interviewing began on November 17, 2005, and continued through August 4, 2006. The survey instrument contained approximately 165 distinct items ranging from demographic descriptions to political attitudes and policy preferences, as well as a variety of social indicators and experiences. All interviewers were bilingual, English and Spanish. Respondents were greeted in both languages and were immediately offered the opportunity to interview in either language. Interviewers also provided a consent script that allowed respondents to opt out of the survey. Demographic variables include age, ancestry, birthplace, education level, ethnicity, marital status, military service, number of people in the household, number of children under the age of 18 living in the household, political party affiliation, political ideology, religiosity, religious preference, race, and sex.

Latino National Survey (LNS) Focus Group Data, 2006 (ICPSR 29601)

Released/updated on: 2015-08-19
Geographic coverage: North Carolina, United States, Fort Worth, Arkansas, Washington, San Diego, Atlanta, Colorado, Denver, Dallas, Arizona, Nevada, District of Columbia, Seattle, San Antonio, Chicago, California, Florida, New York (state), New Jersey, Miami, Iowa, Illinois, Texas, Los Angeles, Georgia, Houston
The focus groups conducted by the research team for the project presented here offer precisely this convergence of both breadth and depth. The team used a common protocol to guide discussion in fifteen focus groups -- with more than 150 participants in nine cities across eight states -- that were designed to include Spanish and English-speaking respondents, in different regions of the country, with differing compositions by generation and country of origin. The number and range of the participants in these Latino focus groups are unique in the social science literature. This study presents the results of a unique data set, the results of fifteen focus groups conducted across the United States with Latino residents, including foreign-born -- both legal and undocumented immigrants and native-born. These data provide more range than allowed by the typical interview-based project and not only give key insights into Latino residents' thoughts about community, language, discrimination, ties to their countries of origin, and the like, but also provide some sense of participants' explanations of their reasoning and motivations, something not achievable through structured survey data alone.

This collection provides information on live births in the United States during calendar year 2006. The natality data in these files are a component of the vital statistics collection effort maintained by the federal government. Birth data is limited to births occurring in the United States to United States residents and nonresidents. Births occurring to United States citizens outside of the United States are not included in this data collection. Part 1 contains data on births occurring within the United States, while Part 2 contains data on births occurring in the United States territories of Puerto Rico, the Virgin Islands, Guam, American Samoa, and the Commonwealth of the Northern Mariana Islands. Beginning in 2005, the United States file no longer includes geographic detail (e.g., mother's state of residence). Geographic variables for the United States Territories file include the territory and county in which the birth occurred and in which the mother resided. Other variables describe the place of delivery, who was in attendance, and medical and health data such as the method of delivery, prenatal care, tobacco and alcohol use during pregnancy, pregnancy history, medical risk factors, and infant health characteristics. Birth and fertility rates and other statistics related to this study can be found in the National Vital Statistics Report in the codebook documentation. Demographic variables include the child's sex and month and year of birth, the parent's age, race, and ethnicity, as well as the mother's marital status, education level, and residency status.
