The National Death Index (NDI) is a centralized database of death record information on file in state vital statistics offices. Working with these state offices, the National Center for Health Statistics (NCHS) established the NDI as a resource to aid epidemiologists and other health and medical investigators with their mortality ascertainment activities. Assists investigators in determining whether persons in their studies have died and, if so, provide the names of the states in which those deaths occurred, the dates of death, and the corresponding death certificate numbers. Investigators can then make arrangements with the appropriate state offices to obtain copies of death certificates or specific statistical information such as manner of death or educational level. Cause of death codes may also be obtained using the NDI Plus service. Records from 1979 through 2011 are currently available and contain a standard set of identifying information on each death. Death records are added to the NDI file annually, approximately 12 months after the end of a particular calendar year. 2012 should be available summer 2014. Early Release Program for 2013 is now available. The NDI service is available to investigators solely for statistical purposes in medical and health research. The service is not accessible to organizations or the general public for legal, administrative, or genealogy purposes.

NCHS has linked data from various surveys with death certificate records from the National Death Index (NDI). Linkage of the NCHS survey participant data with the NDI mortality data provides the opportunity to conduct a vast array of outcome studies designed to investigate the association of a wide variety of health factors with mortality. The Linked Mortality Files (LMF) have been updated with mortality follow-up data through December 31, 2019. Public-use Linked Mortality Files (LMF) are available for 1986-2018 NHIS, 1999-2018 NHANES, and NHANES III. The files include a limited set of mortality variables for adult participants only. The public-use versions of the NCHS Linked Mortality Files were subjected to data perturbation techniques to reduce the risk of participant re-identification. For select records, synthetic data were substituted for follow-up time or underlying cause of death. Information regarding vital status was not perturbed.

This data file supplies the date and cause of death for sample persons included in the NATIONAL HEALTH INTERVIEW SURVEY, 1989 (ICPSR 9583) who died between 1989 and the end of 1991. Linkage information collected on respondents 18 years of age and older as part of the National Health Interview Survey (NHIS) was used to match these respondents to the National Death Index. The vital status information produced from the matches can be linked with the NHIS data to provide a longitudinal component to those data. Variables include survey year, quarter, household number, person number, year of death, month of death, whether an autopsy was performed, vital status classification information, causes of death, and hospital and patient status.

To estimate probabilities of death by cause for a representative United States population, according to age, sex, race, occupation, industry, income, education, residence, country of birth, calendar year, and a number of other demographic and epidemiologic factors. The representative population is derived from selected Bureau of the Census files and is matched to the National Death Index maintained by the National Center for Health Statistics. The Bureau of the Census provides the data processing, coding and management necessary to complete this objective.

This data collection supplies date and cause of death data for sample persons included in the National Health Interview Surveys (NHIS) for the years 1986 through 1994. Beginning with survey year 1986, linkage information was collected on NHIS respondents aged 18 and older to allow for matching with other data systems such as the National Death Index (NDI). The Multiple Cause of Death (MCD) data files contain information on those persons with scores high enough to be considered deceased or scores high enough that they may be included in an analysis as deceased. The Ineligible Cases data files contain person IDs of those NHIS participants under the age of 18 as well as those with insufficient information to permit linkage with the NDI. These cases should be excluded from the NHIS survey data files prior to analysis. Linkage of the NHIS respondents with the NDI provides a longitudinal component to the NHIS that allows for the ascertainment of vital status. The addition of vital status permits the use of NHIS data to estimate survival, mortality, and life expectancy while using the richness of the NHIS questionnaires, both core and supplements, as covariates. These data files must be used in conjunction with the basic NHIS data files (1986 [ICPSR 8976], 1987 [ICPSR 9195], 1988 [ICPSR 9412], 1989 [ICPSR 9583], 1990 [ICPSR 9839], 1991 [ICPSR 6049], 1992 [ICPSR 6343], 1993 [ICPSR 6534], 1994 [ICPSR 6724]). Variables included in the MCD files cover year of interview, quarter, household number, person number, month and year of death, vital status, and causes of death. The Ineligible Cases files contain a person ID that matches columns 3-16 on the NHIS public use data files.

This data file supplies date and cause of death data for sample persons included in the Supplement on Aging (SOA) to the NATIONAL HEALTH INTERVIEW SURVEY, 1984 (ICPSR 8659). It can also be used for the cohort included in the NATIONAL HEALTH INTERVIEW SURVEY: LONGITUDINAL STUDY OF AGING, 70 YEARS AND OVER, 1984-1989 (ICPSR 8719), a follow-up to the SOA. The file contains the date of death for 4,230 persons who died by the end of 1991. It also contains the cause of death for 2,515 persons who died by the end of 1989. Records of participants in the SOA were matched with the National Death Index only if the participant provided all the information after being told that it would be used for matching for 1984-1989. Of the 16,148 participants, 15,974 provided the information and their records were matched to the National Death Index for the years 1984-1989. Of those 15,974, a total of 3,113 matched either on all items (2,640) or on the critical items (473). Records of the 3,113 decedents were then matched with multiple cause of death files only for the years 1984-1989. This file contains the identification number for adding this information to the Supplement on Aging and the Longitudinal Study of Aging files. Also supplied are the underlying cause of death (up to eight multiple causes of death), whether an autopsy was performed, the place of death, and codes for the occupation and industry of the deceased, as reported on the death certificate.

The fetal death data file is maintained by calendar year. The information on fetal deaths was abstracted from the Report of Fetal Death forms received from the States by the National Center for Health Statistics (NCHS) and this file contains a record for each form received. Data from New York, excluding New York City, were submitted in machine readable form. All other data were coded and keyed by the U.S. Bureau of the Census. Special consideration should be given to the following paragraphs concerning the tabulation of fetal death records by NCHS. Fetal death tabulations published by the National Center for Health Statistics/Division of Vital Statistics (NCHS/DVS) in Vital Statistics of the United States, Volume 11, Mortality are by place of residence unless otherwise specified in the tables. Fetal deaths to nonresidents of the United States (foreign residents) are excluded from these tabulations. However, tables by place of occurrence include fetal deaths to nonresidents of the United States, and totals differ from residence tables. Foreign resident records can be identified by codes 52 through 57 and 59 in tape locations 23-24. In addition, the majority of fetal death tables published by NCHS/DVS include only those fetal deaths with stated or presumed gestation of 20 weeks or more (see the Technical Appendix). Those records identified with a 2 in tape location 10 are included in these tabulations. All other records are excluded.

The 1997 birth cohort linked file includes several separate data files. The first file includes linked birth and death certificate data for all US infants born in 1997 who died before their first birthday - referred to as the numerator file. The second file contains information from the death certificate for all US infant death records which could not be linked to their corresponding birth certificates - referred to as the unlinked death file. The third file is the 1997 NCHS natality file for the US with a few minor modifications - referred to as the denominator-plus file. These same three data files are also available for Puerto Rico, the Virgin Islands, and Guam. For the denominator-plus file, selected variables from the numerator file have been added to the denominator file to facilitate processing. These variables include age at death (and recodes), underlying cause of death (and the 61-cause recode), place of accident, and record weight. These variables are the most widely used variables from the numerator file. With the previous file format it was sometimes necessary to combine the numerator and denominator files when performing certain multivariate statistical techniques. Now, when the number of variables required from the numerator file is limited, the denominator-plus file may be used by itself for ease of programming. Infant death identification numbers are also included, so that the same infant can be uniquely identified and matched between the numerator and denominator-plus files.

A longitudinal study which follows the cohort of current residents and discharged residents sampled from the 1985 National Nursing Home Survey (NNHS), thus permitting study of nursing home and hospital utilization over time. The study was conducted in three waves. To supplement the current and discharged resident components, the 1985 NNHS included a new component - the Next-of-Kin (NOK). The NOK, using a Computer Assisted Telephone Interviewing (CATI) system, was designed to collect information about current and former nursing home residents that is not generally available from patient records or other sources in the nursing home. The NNHSF obtains additional information on a portion of the residents for whom a Current Resident Questionnaire (CRQ) or a Discharged Resident Questionnaire (DRQ) was completed. In September 1994, the NNHSF Mortality Public Use Data Tape was released, covering the years 1984-1990. It contains the multiple cause-of-death information for 6,507 subjects from the NNHSF found to be deceased after linking and matching of files with the National Death Index. Information on the mortality tape includes the date of death, region of occurrence and residence, etc. All NNHSF tapes include a patient identification number common across files to allow linkage among them. Data Availability: Public Use data tapes for each wave and the mortality tape are available through the National Technical Information Office (NTIS), NACDA and the ICPSCR at the University of Michigan. The 1985 survey tape includes eight files: the facility questionnaire, nursing staff questionnaire, current resident questionnaire, discharged resident questionnaire, expense questionnaire, nursing staff sampling list, current resident sampling list, discharged resident sampling list. The next-of-kin questionnaire is available on a separate tape. * Dates of Study: 1987-1990 * Study Features: Longitudinal * Sample Size: ** 1987: 6,001 (Wave I) ** 1988: 3,868 (Wave II) ** 1990: 3,041 (Wave III) Links: * Wave I (ICPSR): http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/09813 * Wave II (ICPSR): http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/09838 * Wave III (ICPSR): http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/06142

The data contained in this dataset is based on the Cause Of Death Unit Record File (CODURF) provided by the Australian Coordinating Registry (ACR), the data has been aggregated based on either a single or grouped ICD-10* classification.

Mortality statistics are based on the Cause Of Death Unit Record File (CODURF) provided by the Australian Coordinating Registry (ACR) and are reported by year of occurrence. There can be lags in the registration of deaths with the state or territory registries. Consequently, not all deaths are registered in the year that they occur. In addition, a coroner may investigate a death if the death is unexpected or violent (such as a homicide and suicide), when the identity is unknown, cause of death is not known or if the person is in care or custody. The coronial process can take several years, particularly where an inquest is held, or complex investigations are being undertaken. Therefore, there is a delay in reporting deaths through this process.

Deaths for 2020 and 2021 are preliminary and are subject to change.

The ACT deaths data is collected and maintained by the ACT registrar of Births, Deaths and Marriages (ACT RBDM), which records all medical conditions that directly caused or contributed to the death and were applicable, ie the circumstances surrounding a death (eg. motor vehicle accident).

The National Coronial Information System (NCIS) records and stores information relating to coroner certified deaths for the purposes of retrieval, analysis, interpretation and dissemination to allow for informed death and injury prevention activities.

The Australian Coordinating Registry (ACR) is an agency appointed by state and territory RBDMs and coroners to coordinate and manage approval of coded deaths data.

This data collection presents information about the causes of all recorded deaths occurring in the United States, Puerto Rico, the Virgin Islands, and Guam during 1995. Data are provided concerning underlying causes of death, multiple conditions that caused the death, place of death, residence of the deceased (e.g., region, division, state, county), whether an autopsy was performed, and the month and day of the week of the death. In addition, data are supplied on the sex, race, age, marital status, education, usual occupation, and origin or descent of the deceased. Along with the Combined Territories Public Use file, a subset based on state of occurrence has been created for Puerto Rico, Virgin Islands and Guam. Mortality detail data for 1995 also can be extracted from this file. The mortality detail records are contained in the first 159 positions of these multiple cause records. The multiple cause of death fields were coded from the MANUAL OF THE INTERNATIONAL STATISTICAL CLASSIFICATION OF DISEASES, INJURIES, AND CAUSE-OF-DEATH, NINTH REVISION (ICD-9), VOLUMES 1 AND 2.

Information on the fetal death data tape file was abstracted from the Report of Fetal Death forms received in all the States and the District of Columbia, with a record on the data file for each report of a fetal death received. The data is provided to the National Center for Health Statistics (NCHS) through the Vital Statistics Cooperative Program by the registration offices of all States, the District of Columbia, and New York City. Data from New York, excluding New York City, were submitte d in machine readable form. All other 1992 data were coded and keyed by the U.S. Bureau of the Census. Fetal death data are limited to deaths occurring within the United States to U.S. residents and nonresidents. Fetal deaths occurring to U.S. citizens outside the United States are not included in this data file. In NCHS tabulations by place of residence, fetal deaths to nonresidents of the United States are excluded. The foreign resident records can be identified by code 4 in tape location 7 of the data tape. In addition, the majority of fetal death tables published by NCHS include only those fetal deaths with stated or presumed gestation of 20 weeks or more (see the Technical Appendix). Those records identified with a 2 in tape location 5 are included in these tabulations. All other records are excluded. Effective January 1, 1989, a revised U-S. Standard Report of Fetal Death replaced the 1978 revision. The 1989 revision provides a wide variety of new information on maternal and fetal health characteristics. Questions on complications of labor and delivery and congenital anomalies of fetus were changed from an open-ended question to a checkbox format to improve reporting of information. Several new items were added that improve the data files value for monitoring and research of factors affecting fetal mortality. The Office of Management and Budget revised its designation of metropolitan statistical areas based on figures from the 1990 Census. Effective with the 1990 data file, NCHS has been using these new definitions and codes as indicated in the listing of 320 Metropolitan Statistical Areas (MSAS), Primary Metropolitan Statistical Areas (PMSAS), and New England County Metropolitan Ar eas (NEaSS) included in this documentation. There are also 20 Consolidated Metropolitan Statistical Areas (mSAS), which are made up of PMSAS. Other geographic changes based on the 1990 Census will be implemented later. NCHS has adopted a new policy on release of vital statistics unit record data files. This new policy was implemented with the 1989 vital event files to prevent the inadvertent disclosure of individuals and institutions. As a result, this file does not contain the actual day of the death. The geographic detail is also restricted-only counties and cities of 100,000 or more population based on the 1980 Census as well as metropolitan areas of 100,000 or more population based on the 1990 Census, are identified.
