Behavioral Risk Factor Surveillance System (BRFSS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP).

Mode of Administration

Telephone interview. Interviews for 2004 and later were conducted through computer-assisted telephone interviewing (CATI).

Survey Sample Design

Data collection is conducted separately by each State. Sample design uses State-level, random-digit-dialed probability samples of the adult (age 18 and over) population. Most States currently use disproportionate random sampling methods. The BRFSS was initiated in 1984, with 15 States collecting surveillance data on risk behaviors through monthly telephone interviews. The number of States participating in the survey has increased. Since 2001, 50 States, the District of Columbia, Puerto Rico, Guam, and the Virgin Islands have participated in the BRFSS.

Primary Survey Content

The survey consists of a core of questions asked in all States, standardized optional questions on selected topics that are administered at the State's discretion, a rotating core of questions asked every other year in all States, and State-added questions developed to address State-specific needs. Questions cover behavioral risk factors (for example, alcohol and tobacco use), preventive health measures, HIV/AIDS, health status, limitation of activity, and health care access and utilization.

The objective of the BRFSS is to collect uniform, State-specific data on preventive health practices and risk behaviors that are linked to chronic diseases, injuries, and preventable infectious diseases in the adult population.

Population Targeted

U.S. civilian noninstitutionalized population 18 years of age and older who reside in households with telephones.

Demographic Data

Age, sex, educational attainment, race/ethnicity, household income, employment status, and marital status.

Years Collected

Since 1984.

Schedule

Annual.

Geographic Estimates

National, State; smaller area estimates possible in some States.

National Ambulatory Medical Care Survey (NAMCS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Field personnel meet with participating office-based physicians and instruct them in survey data collection methods. Physicians are asked to complete a 1-page questionnaire (Patient Record Form) on a sample of their office visits during their assigned reporting period.

Survey Sample Design

NAMCS is a national probability sample survey of visits to office-based physicians in the United States. The NAMCS uses a three-stage survey design that involves probability samples of primary sampling units (PSUs), physician practices within PSUs, and patient visits within physician practices. Participating physicians are randomly assigned to a 1-week reporting period during the survey year, and a systematic random sample of patient visits during that period is selected, using a visit sampling rate that varies by the size of the practice, with the intention of obtaining 30 survey forms per physician. In 2005, 25,665 survey forms were collected.

Primary Survey Content

Information is obtained on various aspects of office visits, including physician practice characteristics, patient characteristics, and other visit characteristics. Only visits to the offices of non-Federal physicians classified by the American Medical Association or the American Osteopathic Association as "office-based, patient care" are included. The survey form is redesigned every 2 to 4 years to address changing health data needs. Among the items collected are patient's age, sex, race, and ethnicity; patient's expressed reason for visiting the physician; intentionality of injury, if any; physician's diagnoses; diagnostic services ordered or provided; therapeutic services; ambulatory surgical procedures performed; medications; providers seen; visit disposition; time spent with physician; and expected source of payment.

Population Targeted

The basic sampling unit is the patient visit. Included in the survey are in-person visits made to the offices of nonfederally employed, office-based physicians who are classified by the American Medical Association or the American Osteopathic Association as being primarily engaged in direct patient care. The specialties of anesthesiology, pathology, and radiology are not included. Also not included are contacts by telephone, visits made outside the physician's office, visits in hospitals or institutional settings, and visits made for administrative purposes only. Sample data are weighted to produce national estimates of office visits.

Demographic Data

Patient's age, sex, race, and ethnicity.

Years Collected

Annual from 1973-1981; again in 1985; resumed an annual schedule in 1989.

Schedule

Annual.

Geographic Estimates

National, four U.S. Census Bureau regions.

Notes

The NAMCS is a visit-based survey rather than a population-based survey. Therefore, estimates of incidence and prevalence of disease cannot be computed. The survey is cross-sectional in nature. Multiple visits may be made by the same person within the sample.

National Health and Nutrition Examination Survey (NHANES)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

In-person interview in the household and in a private setting in the mobile examination center. Standardized physical examinations and medical tests in mobile examination centers.

Survey Sample Design

The NHANES uses a stratified multistage probability sample, nationally representative of the U.S. civilian noninstitutionalized population. The NHANES III survey is designed to be nationally representative for either Phase I or II of data collection (1988-1994). The NHANES 1999-2004 survey is designed to give an annual sample that is nationally representative and approximately 5,000 people are examined at 15 locations each year, with oversampling of African Americans, Mexican Americans, adolescents, older adults, and low-income Whites.

The current NHANES is released in 2-year data sets. NHANES 2001-2002 and earlier were used for the 2005 NHQR and NHDR. The sample size is smaller than NHANES III, and the number of geographic units in the sample is more limited. The sample design, weighting, and variance estimation methodology also differ from NHANES III. NHANES 2003-2004, the most recent data release, will be incorporated into future editions of the National Healthcare Quality Report and National Healthcare Disparities Report.

Response Rates

In NHANES III (1984-1994): Household interview response rate is 86 percent and the medical examination response rate is 78 percent.

In NHANES 1999-2000: Household interview response rate is 82 percent and the medical examination response rate is 76 percent.

In NHANES 2001-2002: Household interview response rate is 84 percent and the medical examination response rate is 80 percent.

Primary Survey Content

Chronic disease prevalence and conditions (including undiagnosed conditions), risk factors, diet and nutritional status, immunization status, infectious disease prevalence, health insurance, and measures of environmental exposures. Other topics addressed include hearing, vision, mental health, anemia, diabetes, cardiovascular disease, osteoporosis, obesity, oral health, mental health, and physical fitness.

Population Targeted

For NHANES III, the civilian noninstitutionalized population residing in the United States age 2 months and over. Beginning in 1999, people of all ages are included.

Demographic Data

Age, sex, education, race/ethnicity, place of birth, income, occupation, and industry.

Years Collected

From 1960 to 1994, a total of 7 national examination surveys were conducted. Beginning in 1999, the survey has been conducted continuously. The most recent data release is for the 2003-2004 period.

Schedule

Fielded periodically (1960-1994); continuously beginning in 1999, with data releases occurring in 2-year increments.

Geographic Estimates

National, four U.S. Census Bureau regions (NHANES III).

National Health Interview Survey (NHIS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Personal interview in households using computer-assisted personal interviewing (CAPI), administered by professional interviewers and conducted in English and Spanish (the CAPI Spanish version was initiated in mid-1998). A new NHIS instrument, which uses Blaise® computer-assisted interviewing software, was implemented for the 2004 survey year.

Survey Sample Design

The NHIS uses a stratified multistage probability design that permits a continuous sampling of 328 primary sampling units (PSUs), with oversampling of African Americans and Hispanics. A typical NHIS sample for the data collection years 1995 to 2005 consists of approximately 7,000 second-stage units (segments) within a PSU. The expected sample of 43,000 occupied respondent households yields a probability sample of about 111,000 people. The survey is designed so that the sample scheduled for each week is representative of the target population and the weekly samples are additive over time. In 2004, the survey instrument and data production process were reengineered.

Primary Survey Content

Information is obtained on demographic characteristics, illnesses, injuries, impairments, chronic conditions, utilization of health resources, health insurance, and other health topics. The core household interview asks about everyone in the household. Additional questions are asked of one sample adult and one sample child (under 18 years) per family in the household. The sample adult questionnaire includes chronic health conditions and limitations in activity, health behaviors, health care access, health care provider contacts, immunizations, and AIDS knowledge and attitudes. The sample child questionnaire includes questions about chronic health conditions, limitations in activities, health status, behavior problems, health care access and utilization, and immunizations. Child data are proxy reported by a parent or other knowledgeable adult respondent. Adult sample person data are all self-reported. Special modules are fielded periodically and cover areas such as cancer, prevention, disability, and use of complementary and alternative medicine.

Population Targeted

Civilian noninstitutionalized population residing in the United States, all ages.

Demographic Data

Age, sex, race/ethnicity, education, income, marital status, place of birth, industry, and occupation.

Years Collected

Continuously since 1957. Current sample design began in 1995; current questionnaire design began in 1997.

Schedule

Annual.

Geographic Estimates

National, 4 U.S. Census Bureau regions, some of the 10 Health and Human Services regions, some States, metropolitan and nonmetropolitan areas.

National Hospital Ambulatory Medical Care Survey (NHAMCS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Hospital staff were asked to complete 1-page questionnaires (Patient Record forms) on a sample of their patient visits during an assigned reporting period.

Survey Sample Design

The NHAMCS is a national probability sample survey of visits to emergency departments (EDs) and outpatient departments (OPDs) of non-Federal, short-stay, and general hospitals in the United States. The NHAMCS uses a four-stage probability design that involves samples of primary sampling units (PSUs), hospitals within PSUs, clinics within hospitals, and patient visits within clinics and/or emergency service areas. Hospital staff are asked to complete Patient Record forms for a systematic random sample of patient visits occurring during a randomly assigned 4-week reporting period during the survey year. Sample data are weighted to produce national estimates of patient visits. About 400 EDs and 225 OPDs participate each year. In 2005, 33,605 ED forms and 29,975 OPD forms were completed.

Primary Survey Content

The NHAMCS includes two files: ED visits and OPD visits. Information is obtained on various aspects of patient visits, including patient, hospital, and visit characteristics. The survey form is redesigned every 2 to 4 years to address changing health data needs. Among the items collected are patient's age, sex, race, and ethnicity; patient's expressed reason for visit; intentionality of injury, if any; physician's diagnoses; diagnostic services ordered or provided; procedures provided; medications; providers seen; visit disposition; immediacy with which patient should be seen; and expected source of payment. Items collected that are specific to the ED include mode of arrival, waiting time, duration of time in the ED, initial vital signs, and cause of injury.

Population Targeted

The basic sampling unit is the patient visit. Included in the survey are in-person visits made to EDs and OPDs of non-Federal, short-stay, and general hospitals, exclusive of Federal, military, and Veterans Affairs hospitals, located in the 50 States and the District of Columbia. Telephone contacts and visits for administrative purposes are excluded. NHAMCS is weighted to give national estimates of ED and hospital OPD visits.

Demographic Data

Patient's age, sex, race, and ethnicity.

Years Collected

Since 1992.

National Hospital Discharge Survey (NHDS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Manual sample selection and abstraction of inpatient medical records by U.S. Census Bureau field personnel or automated data collection through the purchase of electronic files from commercial sources, States, or hospitals.

Survey Sample Design

The NHDS uses a three-stage national probability design that includes primary sampling units (PSUs) used for the 1985-1994 National Health Interview Survey (NHIS), hospitals within the PSUs, and discharges within the hospitals. Approximately 300,000 discharges are sampled each year from about 500 hospitals.

Primary Survey Content

Variables collected include age; sex; race; ethnicity; admission and discharge dates (length of stay); discharge status; source of payment; hospital size, ownership, and region; from one to seven diagnoses coded using the ICD-9-CM; and from zero to four procedures using the ICD-9-CM.

Population Targeted

The NHDS contains a sample of discharges from non-Federal, noninstitutional hospitals in the 50 States and the District of Columbia. Only hospitals with an average length of stay for all patients of less than 30 days or with a general (medical/surgical) or children's specialty are included in the survey.

NHDS data are weighted to give national and regional estimates of hospital discharges from non-Federal, noninstitutional hospitals.

Demographic Data

Patient's age, sex, race, and ethnicity.

Years Collected

1965 to present.

Schedule

Annual.

Geographic Estimates

National, four U.S. Census Bureau regions.

Notes

Data on race are not available from some hospitals because the hospitals provide data from billing forms that do not include race as a required item. In general, nonresponse for race in the NHDS is about 22 to 25 percent. Nonresponse for Hispanic origin is greater, at about 60 to 63 percent annually.

National Immunization Survey (NIS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS) and National Immunization Program (NIP).

Mode of Administration

The NIS is a list-assisted random-digit-dialing telephone survey.

Survey Sample Design

In each of 78 Immunization Action Plan areas areas (which together make up the United States), the NIS draws independent quarterly samples of telephone numbers and then uses random-digit dialing (RDD) to identify households that have one or more children ages 19 to 35 months. The telephone interviewer collects vaccination information for each such child and requests consent to contact the providers of the child's vaccinations. In a second phase, a mail survey, the NIS asks the providers to report vaccination information from the child's medical record, which is generally more accurate and complete than the household's information.

Primary Survey Content

Vaccination coverage rates for each of 6 recommended vaccines for the Nation and for each of 78 Immunization Action Plan areas, consisting of the 50 States, the District of Columbia, and 28 large urban areas.

Population Targeted

Children between the ages of 19 and 35 months living in the United States at the time of the interview.

National Nursing Home Survey (NNHS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Data for the survey are obtained through personal interviews with administrators and staff and occasionally with self-administered questionnaires in a sample of about 1,500 facilities.

Survey Sample Design

The sampling method is a stratified two-stage probability design. The first stage selects facilities; the second stage selects residents and discharges.

The primary sampling strata of facilities for the 2004 survey were bed size category and metropolitan area status; earlier surveys were stratified by bed size and certification status. The second-stage sampling of current residents and discharges was carried out by the interviewers at the time of their visits to the facilities in accordance with specific instructions given for each sample facility. A sample of up to 12 current residents per facility was selected.

Primary Survey Content

The NNHS provides information on nursing homes from two perspectives: the provider of services and the recipient. Data about the facilities include characteristics such as size, ownership, Medicare/Medicaid certification, occupancy rate, number of days of care provided, and expenses. For recipients, data are obtained on demographic characteristics, health status, and services received.

The number of nursing homes estimated by the survey is less than the number of nursing homes in the United States because some facilities went out of business and others that did not provide nursing care services during the survey period became ineligible.

Population Targeted

Population residing in long-term care facilities or nursing homes.

Demographic Data

Age, sex, educational attainment, race/ethnicity, marital status, and health status.

Years Collected

1973-1974, 1977, 1985, 1995, 1997, 1999, and 2004.

Geographic Estimates

The data represent nursing homes, their residents, and their staff in the United States. Geographic identifiers are also available by Census region, metropolitan statistical area (MSA) indicator.

National Survey of Family Growth (NSFG)

Sponsor

U.S. Department of Health and Human Services (DHHS), Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS), with additional sponsorship by several Federal agencies within DHHS, including: National Institute for Child Health and Human Development (NICHD); Office of Population Affairs (OPA); CDC's National Center for STD, TB, and HIV Prevention, Division of HIV/AIDS Prevention, National Center for Chronic Disease and Health Promotion (NCCDHP), and Division of Reproductive Health; Office of the Assistant Secretary for Planning and Evaluation (ASPE); and Administration for Children and Families, Children's Bureau.

Mode of Administration

Personal, in-home interviews were conducted in English and Spanish with one person per selected household in a private setting by professional interviewers using computer-assisted personal interviewing (CAPI) based on Blaise® software. A portion of the interview was conducted using audio computer-assisted self-interview to allow respondents greater privacy in answering sensitive questions.

Survey Sample Design

Cycle 6 of the NSFG, conducted from March 2002 through February 2003, represents the 6th in a series of periodically conducted national household surveys based on a stratified multistage probability design. Beginning in 2006 (Cycle 7), the NSFG has become a continuous survey. Cycles 1 to 5 of the NSFG were conducted by NCHS in 1973, 1976, 1982, 1988, and 1995, and included women 15 to 44 years of age. In Cycle 6, an independent sample of men 15 to 44 years of age was added.

The Cycle 6 sample consisted of 121 primary sampling units (PSUs), with oversampling of African Americans, Hispanics, and people ages 15 to 24. The final Cycle 6 sample included 12,571 respondents. The overall response rate was 79 percent, 78 percent for men and 80 percent for women.

Primary Survey Content

The primary purpose of the NSFG is to produce reliable national statistics on factors affecting pregnancy and birth rates, as mandated by Section 306 of the Public Health Service Act, including variables that affect whether sexual activity occurs, whether pregnancy occurs when sexually active, and whether pregnancy results in a live birth. As part of this core mission, information is gathered on a host of related topics such as sociodemographic characteristics; sexual activity; marriage, divorce, and cohabitation; children ever born, as well as pregnancies that did not end in live birth; contraceptive use and the use of family planning services; infertility, impaired fecundity, and the use of infertility services; pregnancy intention and other circumstances surrounding pregnancy; breastfeeding; adoption and the care of nonbiologic children; and attitudes regarding sex, childbearing, and marriage.

In more recent cycles, questions have been added to monitor various indicators related to HIV and risk of sexually transmitted disease, including HIV testing and a range of drug-related and sexual behaviors. With the inclusion of men in Cycle 6, greater attention has been paid to men's experience with fathering.

While the questionnaires are structured somewhat differently for men and women, they are designed to yield essentially comparable data for men and women on key indicators related to fertility, family formation, and reproductive health.

Population Targeted

Civilian, noninstitutionalized men and women ages 15 to 44 residing in the United States. Cycles 1 to 5 were limited to women.

Demographic Data

Age, sex, race, Hispanic origin, education, income, marital/cohabiting status, place of birth, and other variables.

Years Collected

Periodically conducted surveys from 1973-2002. Continuously since June 2006, with the current data collection being part of Cycle 7.

Schedule

Periodic surveys 1973-2002. Continuous since June 2006. First data files planned for release in 2009.

Geographic Estimates

National only. The only public-use geographic variable provided in the Cycle 6 data is a 3-category measure of metropolitan residence.

National Tuberculosis Surveillance System (NTBSS)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for HIV, STD, and TB Prevention (NCHSTP), Division of Tuberculosis Elimination (DTBE).

Mode of Administration

Currently, individual tuberculosis (TB) case reports (report of verified case of tuberculosis, or RVCT) are submitted electronically via the Tuberculosis Information Management System (TIMS), a comprehensive CDC software system for TB surveillance, patient management, and program evaluation.

Survey Sample Design

Since 1953, through the cooperation of State and local health departments, CDC has collected information on the numbers of reported TB cases in the United States.

In January 1993, DTBE implemented an expanded TB surveillance system, which collects additional information for each reported TB case in order to better monitor trends in TB.

Currently data are collected from 60 reporting areas (the 50 States, the District of Columbia, New York City, Puerto Rico, and other jurisdictions in the Pacific and Caribbean).

Primary Survey Content

Number of new TB cases, patient management, and program evaluation.

The expanded surveillance system started in 1993 collects additional data to better monitor and target groups at risk for TB disease, estimate and follow the extent of drug-resistant TB, and evaluate outcomes of TB cases. The RVCT form for reporting TB cases was revised to collect information on occupation, initial drug regimen, HIV test results, history of substance abuse and homelessness, and residence in correctional or long-term care facilities at the time of diagnosis. RVCT Follow Up Report-1 was added to collect drug susceptibility results for the initial M. tuberculosis isolate from patients with culture-positive disease. To evaluate the outcomes of TB therapy, RVCT Follow Up Report-2 was added to collect information on the reason and date therapy was stopped, type of health care provider, sputum culture conversion, use of directly observed therapy, and results of drug susceptibility testing for the final M. tuberculosis isolate from patients with culture-positive disease.

Population Targeted

U.S. civilian noninstitutionalized population.

Demographic Data

Age, sex, race, country of origin, metropolitan designation.

Years Collected

Since 1953.

Schedule

Annual.

Geographic Estimates

National, States.

National Vital Statistics System—Linked Birth and Infant Death Data (NVSS-I)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Linked birth and infant death data are part of the Nation's vital and health statistics. Vital statistics are provided through State-operated registration systems. Administrative records (death certificates) completed by physicians, coroners, medical examiners, and funeral directors, and administrative records (birth certificates) completed by physicians and midwives are filed with State vital statistics offices. Selected statistical information is forwarded to NCHS to be merged into a national statistical file.

Survey Sample Design

NVSS mortality files include data for the 50 States, the District of Columbia, and the territories of Puerto Rico, Virgin Islands, Guam, American Samoa, and the Commonwealth of the Northern Marianas. All deaths (all ages) occurring in those areas are included (approximately 2.3 to 2.4 million annually).

Standard forms for the collection of the data and model procedures for the uniform registration of the events are developed and recommended for State use through cooperative activities of the States and NCHS.

Software is available to automate coding of medical information on the death certificate, following World Health Organization rules specified in the International Classification of Diseases (ICD).

In the linked birth and infant death data set, the information from the death certificate is linked to the information from the birth certificate for each infant less than age 1 who dies in the United States, Puerto Rico, the Virgin Islands, and Guam.

Primary Survey Content

The linked files include information from death and birth certificates. The vital statistics general mortality data are a fundamental source of geographic and cause-of-death information and some demographic information. The birth certificate is the primary source of demographic information, such as age, race, and Hispanic origin of the parents; maternal education; live birth order; and mother's marital status; and of maternal and infant health information, such as birth weight, period of gestation, plurality, prenatal care usage, and maternal smoking.

Population Targeted

National.

Demographic Data

Age, race, sex, Hispanic origin of the parents.

Years Collected

Linked data are available for the data years 1983-1991 and 1995-2004.

Schedule

Data are collected/produced annually.

Geographic Estimates

National, by State.

Place of death is classified by State and county. In residence classification, all deaths are allocated to the usual place of residence as reported on the death certificate and are classified by State, county, and city. The public use file identifies counties of 250,000 population or more.

National Vital Statistics System—Mortality (NVSS-M)

Sponsor

U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Administrative records (death certificates) completed by funeral directors, physicians, medical examiners, and coroners are filed with State vital statistics offices; selected statistical information is forwarded to NCHS to be merged into a national statistical file. Beginning with 1989, revised standard certificates replaced the 1978 versions; implementation of the next revision, for 2003, is being phased in by the States. Demographic information on the death certificate is provided by the funeral director and is based on information supplied by an informant. Medical certification of cause of death is provided by a physician, medical examiner, or coroner.

Survey Sample Design

NVSS mortality files include data for the 50 States, the District of Columbia, and the territories of Puerto Rico, Virgin Islands, Guam, American Samoa, and the Commonwealth of the Northern Marianas. All deaths occurring in those areas are included (approximately 2.3 to 2.4 million annually).

Primary Survey Content

Year of death, place of decedent's residence, place death occurred, age at death, day of week and month of death, Hispanic origin, race, marital status (beginning in 1979), place of birth, sex, underlying and multiple causes of death for all States, injury at work (beginning in 1993), hospital and patient status, and educational attainment (beginning in 1989) for selected States.

Population Targeted

U.S. population.

Demographic Data

Sex, race, Hispanic origin (beginning in 1984), age at death, place of decedent's residence, educational attainment (beginning in 1989) for selected States, and marital status. Race and ethnic origin are separate items on the death certificate. Beginning with 1992 data, California, Hawaii, Illinois, New Jersey, New York, Texas, and Washington reported expanded Asian and Pacific Islander categories of Asian Indian, Korean, Vietnamese, Samoan, and Guamanian. The rest of the States reported a combined Other Asian and Pacific Islander category in addition to the categories of White, Black, American Indian, Chinese, Hawaiian, Japanese, and Filipino that all States report. As of 1997, all States report Hispanic origin. The categories reported include Mexican, Puerto Rican, Cuban, Central and South American, and Other Hispanic. Beginning with data for 2003, multiple-race data will be available for selected States.

Years Collected

The data system began in 1880, but not all States participated before 1933. Coverage for deaths has been complete since 1933.

Schedule

Annual.

Geographic Estimates

National, regional, State, and county. Beginning with 1989 data, some changes were initiated to increase confidentiality protection. Identifying information, including date of death and geographic identifiers for counties of less than 100,000 population, is not available for public use.
