The mortality data are based on information from all death certificates filed in the fifty states and the District of Columbia. Deaths of nonresidents (e.g. nonresident aliens, nationals living abroad, residents of Puerto Rico, Guam, the Virgin Islands, and other territories of the U.S.) and fetal deaths are excluded.Mortality data from the death certificates are coded by the states and provided to NCHS through the Vital Statistics Cooperative Program or coded by NCHS from copies of the original death certificates provided to NCHS by the State registration offices. For more information, see Technical Appendix from Vital Statistics of United States: 1999 Mortality. About suppressed data and unreliable rates:Statistics representing fewer than ten persons (0-9) are suppressed.See Assurance of Confidentiality for more information.
Rates are marked as "unreliable" when the death count is less than 20.
About cause of death classification: The underlying cause-of-death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." Underlying cause-of-death is selected from the conditions entered by the physician on the cause of death section of the death certificate. When more than one cause or condition is entered by the physician, the underlying cause is determined by the sequence of conditions on the certificate, provisions of the ICD, and associated selection rules and modifications.
Causes of death are classified in accordance with the International Classification of Disease. Deaths for 1979-98 are classified using the Ninth Revision (ICD-9). Deaths for 1999 and beyond are classified using the Tenth Revision (ICD-10).
Beginning with data for 2006, the valid ICD-10 codes used to classify causes of death changed. Effective with the 2006 data year, 18 codes were introduced as valid causes of death, and 4 codes were discontinued. Effective with the 2007 data year, 4 codes were introduced as valid causes of death, and 2 codes were discontinued. See ICD-10 Changes for more information.
Beginning with data for 2001, NCHS introduced categories *U01-*U03 for classifying and coding deaths due to acts of terrorism. The asterisks before the category codes indicate that they are not part of the International Classification of Diseases, Tenth Revision (ICD-10). Description of the specific 4-digit codes can be found at NCHS Classifications of Diseases, and Functioning & Disability: Appendix I. Deaths classified to the terrorism categories are included in the categories for Assault (homicide) and Intentional self-harm (suicide) in the 113 cause-of-death list. Additional information on these new categories can be found at NCHS Classifications of Diseases, and Functioning & Disability: Classification of Death and Injury Resulting from Terrorism.
About race and ethnicity reporting: Race and Hispanic origin are reported separately on the death certificate in accordance with standards set forth by the Office of Management and Budget. The American Indian or Alaska Native race category includes: North, Central, and South American Indians, Eskimos, and Aleuts. The Asian or Pacific Islander race category includes Chinese, Filipino, Hawaiian, Japanese, and Other Asian or Pacific Islanders.
Hispanic origin was not reported on the death certificate for some deaths. On the mortality file, missing Hispanic origin information is coded as "not stated". There is no corresponding population figure for this group. Therefore, deaths with Hispanic origin not stated are excluded when death rates are calculated by Hispanic origin.
Information included on the death certificate about the race and Hispanic ethnicity of the decedent is reported by the funeral director as provided by an informant, often the surviving next of kin, or, in the absence of an informant, on the basis of observation. Race and ethnicity information from the census is by self-report. To the extent that race and Hispanic origin are inconsistent between these two data sources, death rates will be biased. Studies have shown that persons self-reported as American Indian, Asian, or Hispanic on census and survey records may sometimes be reported as white or non-Hispanic on the death certificate, resulting in an underestimation of deaths and death rates for the American Indian, Asian, and Hispanic groups. Bias also results from undercounts of some population groups in the census, particularly young black males, young white males, and elderly persons, resulting in an overestimation of death rates.In "Quality of death rates by race and Hispanic origin: A summary of current research, 1999," the authors estimate that the misclassification and under-coverage result in overstated death rates for the white and black populations (1% and 5%, respectively) and understated death rates for other population groups (American Indians, 21%; Asian or Pacific Islanders, 11%; and Hispanics, 2%). See also The validity of race and Hispanic Origin reporting on death certificates in the United States.
For 1979-2002, all 50 States and the District of Columbia collected race data on the death certificates using four single-race categories (American Indian or Alaska Native, Asian or Pacific Islander, Black, and White) in accordance with the 1977 OMB standards, allowing only a single race to be reported. Beginning with the 2003 data year, some States began collecting race data in accordance with the 1997 OMB standards, allowing one or more of five race categories to be reported. In order to provide uniformity and comparability of mortality data during the transition from the single-race format to the multiple-race format, NCHS is "bridging" the race responses of those for whom more than one race is reported (multiple race) to one of the single-race categories. The bridging procedure is similar to the procedure used to bridge multiple-race population estimates. Multiple-race decedents are imputed to a single race (White, Black, American Indian or Alaska Native, or Asian or Pacific Islander) according to their combination of races, Hispanic origin, sex, and age indicated on the death certificate. The imputation procedure is described in detail atNCHS Procedures for Multiple-Race and Hispanic Origin Data.
For more discussion of race and ethnicity data, see Race and Ethnicity Questions.
About "Not Stated" age or ethnicity: Deaths of persons with Age "Not Stated" are included in "All" counts and rates, but are not distributed among age groups, so are not included in age-specific counts, age-specific rates or in any age-adjusted rates.
Data for the "Not Stated" age category or the "Not Stated" Hispanic Origin category cannot be combined with any other specified age group or Hispanic Origin categories.
Death rates are not calculated specifically for the "Not Stated" groups because there are no corresponding population denominator data for these groups.
Notes: Population denominator data are not available for the "Not stated" category, thus rates are flagged as "not applicable."
Deaths of persons with unknown or "Not Stated" Hispanic origin are included in "All" counts and rates, but are not distributed among Hispanic Origin groups, so are not included in the Hispanic Origin specific counts and rates .See About "Not Stated" age or ethnicity for more information.
See Race and Ethnicity Questionsfor more information about the issues of race categories and ethnicity in the data.
The Hispanic Origin categories are identified by two columns, labels and codes, in data extracts.
Step 4.

How? See "How do I select items from the list box?"Notes: Note that rates and populations are shown as "Not Applicable" for place of death.
The Place of Death categories changed in 2003.The "Medical Facility - Status unknown" category is only available in years 1999-2002.The "Hospice Facility" category is only available in years 2003 and later.Death counts for these categories are shown as "Missing" for those years when the data are unavailable.
Erratum: Between December 15, 2011 and February 22, 2012, the number of deaths by "Place of Death" reported in CDC WONDER for the years 1999-2002 were inaccurate for the following categories:Decedent's home, Hospice Facility, and Nursing home/long term care.We regret this error and apologize for any inconvenience.
Data are identified by two columns, labels and codes, in data extracts.
Step 6. Select underlying cause of death:Select categories that represent the underlying cause of death from the death certificate.Only one underlying cause of death is indicated for each death.Deaths are coded to the International Classification of Disease Tenth Revision (ICD-10) codes.The ICD system is organized by chapters, sub-chapters and codes.Selected causes are also grouped into categories for mortality analysis.Any number of causes can be specified here. However, you can only limit data to one of the lists for any single query.Be sure the Radio Button is set to your choice. Pick between: ICD-10 Codes listed as chapters, sub-chapters and individual codes
ICD-10 113 Groups for selected causes of death
ICD-10 130 Groups for selected causes of infant mortality
Drug/Alcohol Induced Causes
Injury Intent and Mechanism
Hints: Only those ICD codes and causes that are used to classify underlying causes of death in the mortality dataare available in the Finder for this section. Symptoms are not classified as underlying causes of death.
Deaths in the years 1999 and later are coded to the tenth revision of the International Classification of Diseases (ICD-10).There are 113 selected causes of death groups for the ICD-10 codes.
When you select a code, remember that some deaths are coded to the 3 length code, and not the more detailed designation.Thus some deaths may be excluded from your data selection if your criteria are limited to only 4 length codes.For example, the ICD-10 code A09 is the correct specification; A09.0 will not pick up deaths coded A09.
The causes of death are identified by two columns, labels and codes, in data extracts.
Notes: About the International Classification of Diseases:The mortality data are compiled in accordance with the World Health Organization (WHO) regulations, which specify that member nations classify and code causes of death in accordance with the current revision of the International Statistical Classification of Diseases and Related Health Problems (ICD). The International Classification of Diseases is developed collaboratively between the World Health Organization (WHO) and 10 international centers, for purposes of ensuring that medical terms reported on death certificates are internationally comparable and lend themselves to statistical analysis. The ICD has been revised approximately every 10 years since 1900 in order to reflect changes in understanding of disease mechanisms and in disease terminology.
See also ICD 10th revision notes.
ICD-10 CodesLimit the data to any number of causes of death, for selected chapters, sub-chapters or codes.The default selection is "all causes" of death.How? Click the Radio Button to the left of the box, to pick your preferred list.
Select one or more items from the list to limit your data. The default value for any list is all causes of death.Hints: See How do use a Finder? to learn more about search options, expanding or collapsing selected items,and displaying details for selected items in the Finder.

You may also enter values by hand, one code per line, in the Advanced mode.Use the Finder to see the correct code format. For example, "I20-I25" is the ICD-10 code for ischemic heart diseases.
See Finder Tool help for more hints.
Notes: The International Classification of Disease (ICD) 10th revisionis used to represent the causes of death for the years 1999 and later.The ICD system is organized by chapters, sub-chapters and codes.
ICD-10 uses a 4-length alphanumeric coding scheme. Each of the 21 chapters in ICD-10 is classified to a letter or letters of the alphabet. Infectious disease codes in Chapter 1, for example, begin with an "A" or "B". Thus, Acute poliomyelitis is associated with the codes A80.0-A80.9 and Viral hepatitis is classified as B15.0-B19.9. The ICD 10 system begins codes with a letter from the alphabet, followed by two numerals,then a decimal point to indicate subordinate position, and then more numerals.Some causes of death are represented by 3 length codes, although most causes of death are represented by 4 length codes (format A12.3).Greater detail than 4 length codes are not included in the data.
About Underlying Cause of Death:The underlying cause-of-death is defined by the World Health Organization (WHO) as "the disease or injury which initiated the train of events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury." Underlying cause-of-death is selected from the conditions entered by the physician on the cause of death section of the death certificate. When more than one cause or condition is entered by the physician, the underlying cause is determined by the sequence of conditions on the certificate, provisions of the ICD, and associated selection rules and modifications.
Each death certificate contains a single underlying cause of death.
Only those ICD codes that are used to classify underlying causes of death in the mortality dataare available in the Finder for selecting underlying causes of death. Symptoms are not classified as underlying causes of death.
About changes in ICD-10 codes: The valid ICD-10 codes used to classify cause of death change over time, refer to table below for details.Effective with the 2020 data year, 1 code was introduced as a valid cause of death. Effective with the 2019 data year, 1 code was introduced as a valid cause of death. Effective with the 2011 data year, 33 codes were introduced as valid causes of death. Effective with the 2009 data year, 5 codes were introduced as valid causes of death, and 11 codes were discontinued. Effective with the 2007 data year, 4 codes were introduced as valid causes of death, and 2 codes were discontinued. Effective with the 2006 data year, 18 codes were introduced as valid causes of death, and 4 codes were discontinued. The World Health Organization (WHO) added code I27.2 in 2003. Prior to 2003, if the certifier listed "secondary pulmonary hypertension" the condition would be coded I27.0 because there was no code for secondary pulmonary hypertension. After code I27.2 was added in 2003, the number of deaths coded to I27.0 dropped significantly.New causes of death in 2020ICD-10 CodeTitleU07.1 COVID-19 New causes of death in 2019ICD-10 CodeTitleU07.0 Vaping related disorder New causes of death in 2011ICD-10 CodeTitle B17.9 Acute viral hepatitis, unspecified D68.5 Primary thrombophilia D68.6 Other thrombophilia D89.3 Immune reconstitution syndrome E88.3 Tumor lysis syndrome G14 Postpolio syndrome G21.4 Vascular parkinsonism H54.9 Unspecified visual impairment (binocular) I72.5 Aneurysm and dissection of other precerebral arteries J12.3 Human metapneumovirus pneumonia J21.1 Acute bronchiolitis due to human metapneumovirus K12.3 Oral mucositis (ulcerative) K35.2 Acute appendicitis with generalized peritonitis K35.3 Acute appendicitis with localized peritonitis K35.8 Acute appendicitis, other and unspecified L89.0 Stage I decubitus ulcer and pressure area L89.1 Stage II decubitus ulcer L89.2 Stage III decubitus ulcer L89.3 Stage IV decubitus ulcer L89.9 Decubitus ulcer and pressure area, unspecified N18.1 Chronic kidney disease, stage 1 N18.2 Chronic kidney disease, stage 2 N18.3 Chronic kidney disease, stage 3 N18.4 Chronic kidney disease, stage 4 N18.5 Chronic kidney disease, stage 5 N42.3 Dysplasia of prostate O14.2 HELLP syndrome O43.2 Morbidly adherent placenta O96.0 Death from direct obstetric cause occurring more than 42 days but less than one year after delivery O96.1 Death from indirect obstetric cause occurring more than 42 days but less than one year after delivery O96.9 Death from unspecified obstetric cause occurring more than 42 days but less than one year after delivery O97.0 Death from sequelae of direct obstetric cause O97.1 Death from sequelae of indirect obstetric cause O97.9 Death from sequelae of obstetric cause, unspecified O98.7 Human immunodeficiency [HIV] disease complicating pregnancy, childbirth and the puerperium X34.0 Victim of cataclysmic earth movements caused by earthquake X34.1 Victim of tsunami X34.8 Victim of other specified effects of earthquake X34.9 Victim of unspecified effect of earthquake New causes of death in 2009ICD-10 CodeTitle A09.0 Other and unspecified gastroenteritis and colitis of infectious origin A09.9 Gastroenteritis and colitis of unspecified origin K52.3 Indeterminate colitis R26.3 Immobility R63.6 Insufficient intake of food and water due to self neglect New causes of death in 2007ICD-10 CodeTitle J09 Influenza due to identified avian influenza virus U04.9 Severe acute respiratory syndrome [SARS], unspecified X59.0 Exposure to unspecified factor causing fracture X59.9 Exposure to unspecified factor causing other and unspecified injury New causes of death in 2006ICD-10 CodeTitle B33.4 Hantavirus (cardio)-pulmonary syndrome [HPS][HCPS] G90.4 Autonomic dysreflexia I15.0 Renovascular hypertension I15.9 Secondary hypertension, unspecified K22.7 Barrett's esophagus K85.0 Idiopathic acute pancreatitis K85.1 Biliary acute pancreatitis K85.2 Alcohol-induced acute pancreatitis K85.3 Drug-induced acute pancreatitis K85.8 Other acute pancreatitis K85.9 Acute pancreatitis, unspecified M31.7 Microscopic polyangiitis M79.7 Fibromyalgia P91.6 Hypoxic ischemic encephalopathy of newborn R29.6 Tendency to fall, not elsewhere classified R50.2 Drug-induced fever R50.8 Other specified fever W46 Contact with hypodermic needle New causes of death in 2003ICD-10 CodeTitle I27.2 Other secondary pulmonary hypertension Discontinued causes of death in 2009ICD-10 CodeTitle A09Diarrhea and gastroenteritis of infectious origin F11.0Mental and behavioral disorders due to use of opioids, acute intoxication F12.0Mental and behavioral disorders due to use of cannabinoids, acute intoxication F13.0Mental and behavioral disorders due to use of sedatives or hypnotics, acute intoxication F14.0Mental and behavioral disorders due to use of cocaine, acute intoxication F15.0Mental and behavioral disorders due to use of other stimulants, including caffeine, acute intoxication F16.0Mental and behavioral disorders due to use of hallucinogens, acute intoxication F17.0Mental and behavioral disorders due to use of tobacco, acute intoxication F18.0Mental and behavioral disorders due to use of volatile solvents, acute intoxication F19.0Mental and behavioral disorders due to multiple drug use and use of other psychoactive substances, acute intoxication K51.1Ulcerative (chronic) ileocolitis Discontinued causes of death in 2007ICD-10 CodeTitle F10.0Mental and behavioral disorders due to use of alcohol, acute intoxication X59 Exposure to unspecified factor Discontinued causes of death in 2006ICD-10 CodeTitle I25.2 Old myocardial infarction K85 Acute pancreatitis R50.0 Fever with chills R50.1 Persistent fever
About ICD-10 cause of death codes O00-O99:Between 2003 and 2017, states were incrementally implementing a pregnancy status checkbox which affected the comparability of data between states. In addition, evaluation of data quality indicated errors following adoption of the checkbox. Beginning with 2018 data, after all states had implemented a checkbox, NCHS restricted use of the checkbox to decedents aged 10-44 years to mitigate probable errors. For more information, please refer to Maternal Mortality Statistics for 2018 at: -mortality/.
About deaths due to acts of terrorism: Beginning with data for 2001, NCHS introduced categories *U01-*U03 for classifying and coding deaths due to acts of terrorism. The asterisks before the category codes indicate that they are not part of the International Classification of Diseases, Tenth Revision (ICD-10). Description of the specific 4-digit codes can be found at NCHS Classifications of Diseases, Functioning and Disability: Appendix I. Deaths classified to the terrorism categories are included in the categories for Assault (homicide) and Intentional self-harm (suicide) in the 113 cause-of-death list. Additional information on these new categories can be found at NCHS Classifications of Diseases, Functioning and Disability: Classification of Death and Injury Resulting from Terrorism. Terrorism related deaths in this data do not represent a final count of deaths resulting from the terrorist attacks on September 11, 2001, as this figure had not been determined. As of October 24, 2002, death certificates were issued for 2,957 of the estimated 3,028 individuals believed to have died as a result of the September 11, 2001 attacks. Of these, four were issued for terrorists and are classified as suicides. The criteria for issuing a death certificate for those believed to have died in the attacks differed by state, reflecting differences in state laws regarding death certification. Pennsylvania issued a death certificate for every individual, including the terrorists. Death certificates were not issued for any of the terrorists in Virginia or New York City. Virginia issued a death certificate only for those victims whose remains were identified. New York City issued a death certificate for those whose remains were identified or, if remains were not recovered, for those whose families applied for a death certificate. For more detailed information regarding New York City's processing of these deaths, see Deaths in World Trade Center Terrorist Attacks---New York City, 2001.
