Caveats

Each rate is a crude rate: the death count divided by the resident population, with no adjustment for a state's or county's age mix.
Drug overdose here counts only a death CDC classified as unintentional or of undetermined intent; a death by drug overdose that a medical examiner ruled a suicide is counted under suicide instead, not here, so this figure differs in definition from this site's other overdose figures on /health/drug-overdose-deaths/, which include every intent.
Firearm deaths (all intents) includes firearm suicide, firearm homicide, unintentional firearm deaths and others; it is not a category alongside firearm suicide and firearm homicide but a total that contains both, so the three do not add to a fourth figure.
A trailing-twelve-months figure is a rolling count for the 12 months ending in the named month, not a single month's deaths, and CDC has not finished processing every death certificate in that window; suicide, homicide and firearm figures run about 4 months behind CDC's own processing date and drug overdose about 6.
A county or state with fewer than about 10 deaths in a period has no published count, to protect the privacy of the people involved; CDC substitutes a smoothed statistical estimate of the rate in many of these cases rather than publishing none, noted where it applies.
This file has no rate for the United States as a whole; only states, the District of Columbia and Idaho's counties are covered.

Where sources disagree

Suicide, homicide and firearm deaths, Idaho, 2024: CDC's VSRR provisional drug overdose file publishes 326. This dataset counts 293 Idaho drug overdose deaths in calendar year 2024, classified as unintentional or of undetermined intent only. The VSRR file (this site's /health/drug-overdose-deaths/) counts 326 for the 12 months ending December 2024, on a rolling window rather than a calendar year, and includes every intent, including an overdose a medical examiner ruled a suicide. The two are not the same measurement and are not expected to match.

Measures

Suicide, homicide and firearm deaths (count): Number of deaths from suicide, homicide, firearm injury or drug overdose in a calendar year.
Suicide, homicide and firearm death rate (per 100k): Deaths from suicide, homicide, firearm injury or drug overdose per 100,000 residents in a calendar year, not age-adjusted.
Suicide, homicide and firearm deaths, 12 months ending (count): Provisional number of deaths from suicide, homicide, firearm injury or drug overdose in the 12 months ending in the named month.
Suicide, homicide and firearm death rate, 12 months ending (per 100k): Provisional deaths from suicide, homicide, firearm injury or drug overdose per 100,000 residents, in the 12 months ending in the named month, not age-adjusted.

Leading causes of death

NCHS's count and age-adjusted rate of deaths by state for the ten leading underlying causes of death, including suicide, drawn from death certificates.

Organization: Centers for Disease Control and Prevention
Dataset: NCHS - Leading Causes of Death: United States
Geography: States, the District of Columbia and the nation
Time coverage: 1999-2017
Update frequency: Annual (discontinued; not extended past 2017)
Published: 2019

Methodology: https://www.cdc.gov/nchs/nvss/mortality_tables.htm

Our copy: NCHS - Leading Causes of Death: United States

Caveats

This file ends in 2017 and NCHS has not published a newer state-level version of it; CDC's WONDER tool has more recent mortality data but does not offer a state-level figure through an interface this site can pull from automatically, so these figures are not updated past 2017.
The age-adjusted rate removes the effect of a state's age mix so states can be compared; it is not the rate a resident of that state actually experienced, which the raw death count and the state's population reflect instead.
Each death is coded to exactly one underlying cause by the state that certified it, so these ten causes do not overlap and, apart from rounding, sum to all deaths from these causes; they do not sum to all deaths from every cause, since causes outside the leading ten are not included here.

Measures

Deaths by leading cause (count): Number of deaths from one of the ten leading underlying causes of death.
Age-adjusted death rate by leading cause (per 100k): Deaths from one of the ten leading underlying causes of death per 100,000 residents, age-adjusted to the 2000 U.S. standard population.

Life expectancy

NCHS's annual state life tables: life expectancy at birth by state and by sex, from one calendar year of death records and population estimates.

Organization: Centers for Disease Control and Prevention
Dataset: U.S. State Life Expectancy by Sex
Geography: States, the District of Columbia and (2018-2020) the nation
Time coverage: 2018-2021
Update frequency: Annual, roughly three years behind the current year
Published: September 2026

Our copy: U.S. State Life Expectancy by Sex

Caveats

Each year is a period life table built from that single calendar year's deaths and population, not a cohort followed over time or a multi-year average.
NCHS publishes one state life-expectancy release per calendar year and runs about three years behind; 2021 is the most recent as of this dataset's retrieval.
The 2021 release does not include a United States national figure.

Measures

Life expectancy at birth (years): Expected years of life at birth, based on that year's death rates.

Kindergarten vaccination and exemptions

State reports of estimated vaccination coverage and exemption rates among children entering kindergarten, collected by CDC's School Vaccination Assessment Program.

Organization: Centers for Disease Control and Prevention
Dataset: Vaccination Coverage and Exemptions among Kindergartners
Geography: States, the District of Columbia and the nation
Time coverage: 2009-2010 to 2025-2026

Our copy: Vaccination Coverage and Exemptions among Kindergartners

Caveats

Each figure is a state's own report for that school year; states use different survey methods (a full census of kindergartners, or a sample) and a change from one year to the next can partly reflect a change in method.
A state that did not require a vaccine, or did not report a figure, has no value for that school year rather than a coverage rate.
One coverage figure, MMR (PAC), is CDC's modeled Potentially Achievable Coverage: the MMR coverage rate that would result if every kindergartner without a documented vaccine exemption were up to date, not a directly measured coverage rate like the others.
Any Exemption is not always the sum of Medical Exemption and Non-Medical Exemption: CDC counts a child with at least one exemption once under Any Exemption, and in a few states exemption counts are reported per vaccine rather than per child, which can inflate the reported number of exemptions.

Measures

Kindergarten vaccine exemption rate (percent): Share of kindergartners with an exemption from one or more required vaccines.
Kindergartners with a vaccine exemption (count): Number of kindergartners with an exemption from one or more required vaccines.
Kindergarten vaccination coverage (percent): Share of kindergartners who have received a required vaccine, by vaccine.
Kindergarten enrollment surveyed (people): Number of children enrolled in kindergarten covered by that year's state vaccination report.

Drug overdose deaths

NCHS provisional counts of drug overdose deaths and all-cause deaths, each expressed as a rolling 12-month total, based on death certificates before some cases have completed investigation.

Organization: Centers for Disease Control and Prevention
Dataset: VSRR Provisional Drug Overdose Death Counts
Geography: States, the District of Columbia and the nation
Time coverage: 2015-01 to 2026-03
Update frequency: Monthly
Published: August 12, 2026
Original file: https://data.cdc.gov/resource/xkb8-kh2a.json
Methodology: https://www.cdc.gov/nchs/nvss/vsrr/drug-overdose-data.htm
License: Public domain. U.S. federal government work.
Our copy: VSRR Provisional Drug Overdose Death Counts

Caveats

Each figure is a rolling 12-month total ending in the named month, not a count for that single month.
These are provisional counts based on death certificates that may not yet be complete; NCHS also publishes a model-based predicted value that adjusts for investigations still pending, and this dataset carries only the reported count, not that estimate.
A month with no figure is below NCHS's reporting threshold and suppressed, not zero; for Idaho this leaves most months for heroin and methadone unreported.
The drug categories overlap by the ICD-10 codes they cover and do not add up to the overdose death total; a death coded to heroin, for example, is also counted under the broader opioid category.
Deaths from all causes are shown here as the context NCHS publishes alongside overdose deaths, not as a comparable series in its own right.

Where sources disagree

Deaths from all causes, 12 months ending, Idaho, 2024-12: the Census Bureau's population estimates publishes 16,782. This dataset's figure (16,785) is provisional deaths from all causes recorded on Idaho death certificates in the 12 months ending December 2024, counted by the National Center for Health Statistics. The Census Bureau's deaths component of population change for 2024, which this site publishes as population.deaths on /population/births-deaths/, covers the 12 months ending June 30, 2024 and is a modelled input to a population estimate rather than a certificate count. The two run over different twelve-month windows and are produced for different purposes.

Measures

Drug overdose deaths, 12 months ending (count): Provisional count of drug overdose deaths in the 12 months ending in the named month.
Deaths from all causes, 12 months ending (count): Provisional count of deaths from all causes in the 12 months ending in the named month.
Drug overdose deaths by drug category, 12 months ending (count): Provisional count of drug overdose deaths involving a specific drug or drug class, in the 12 months ending in the named month.
Overdose deaths with drugs specified, 12 months ending (percent): Share of drug overdose deaths in the 12 months ending in the named month for which the death certificate names at least one specific drug.

Recent causes of death

Our copy: NCHS VSRR Quarterly Provisional Estimates of Death Rates

Caveats

Each figure is age-adjusted to the 2000 U.S. standard population and covers the 12 months ending in the named month, on a provisional count that CDC still revises as death certificates finish processing.
A cause tied to an external event (suicide, homicide, drug overdose, a firearm or a fall) takes longer for a medical examiner or coroner to code than a natural cause like cancer or heart disease, so these causes are consistently a quarter or two further behind than the rest; a missing recent quarter is not yet published, not a zero.
This dataset carries a rate for every state, but only Idaho's and the nation's are pulled here; this site's cross-state comparison of leading causes of death is the older, final NCHS series covering 1999 to 2017.

Measures

Age-adjusted death rate by leading cause, 12 months ending (per 100k): Provisional deaths from a leading cause per 100,000 residents, age-adjusted to the 2000 U.S. standard population, in the 12 months ending in the named month.
