- 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.

| HIV disease | 0.2 |
- 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.

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.

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 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.
