Never set beside OASIS overdose deaths as one series. Read directly with DuckDB over Parquet.","limitations":"Unintentional or undetermined drug overdose deaths only, by county of residence: not every drug overdose death. Counties with 1 to 9 deaths get a CDC model estimate in place of an observed rate (rate_modeled true), so many county rates are estimates. Georgia DPH's OASIS drug overdose deaths also count drug suicides and assaults, and the two sources process death records separately, so the counts differ: usually a little lower here (Fulton 2024: 222 here, 229 in OASIS) but not always (Fulton 2021: 263 here, 255 in OASIS). Never compare the two head to head or mix them in one series. Where a county had 1 to 9 deaths CDC withholds the count (shown as '1-9': num_deaths NULL, never a zero, never backed out of a total) and publishes instead an estimate from its Bayesian model, which borrows strength from neighboring counties (rate_modeled true), with a 95% credible interval; a modeled rate is not deaths divided by population, and where CDC flags the modeled rate as unstable and does not publish it (-999 in the source) the rate and interval are NULL. 61% of county-years had 1-9 deaths (a modeled estimate, or no rate on 30). So county counts do not add up to a Georgia total (no statewide row is published, and none is built here), and rates cannot be pooled or averaged across counties from this table: no population is published, and modeled estimates are not deaths divided by population. Rates are crude (deaths per 100,000 residents of all ages), not age-adjusted, so places with older or younger populations are not directly comparable. Final annual data as of 2026-05-14. Not included: CDC's provisional trailing 12 months (April 2025 to March 2026), which CDC revises and rolls forward monthly; every row here is a calendar year. CDC's measure counts deaths whose intent was unintentional or undetermined (its cause-of-death codes are in CDC's data dictionary, not in this source file). OASIS's case definition (underlying cause X40-X44, X60-X64, X85, Y10-Y14) adds intentional self-poisoning and assault by drugs, and OASIS publishes age-adjusted rates, drug types (opioids, fentanyl, heroin, methadone) and demographics, with final calendar 2025.
