💀 CDC WONDER Mortality Data Scraper

🚀 Export CDC WONDER mortality records in seconds. Pull underlying cause-of-death counts, crude rates, and age-adjusted rates for any U.S. state, year, sex, age group, or ICD-10 chapter - no account required. Download as CSV, Excel, JSON, or XML.

The CDC WONDER Mortality Scraper extracts data directly from the CDC's Wide-ranging ONline Data for Epidemiologic Research (WONDER) public API. Every record contains the number of deaths, crude rate per 100,000 population, and age-adjusted mortality rate as published by the U.S. National Vital Statistics System. No login, no CAPTCHA, no manual exports required.

The dataset covers six CDC WONDER mortality databases including the Underlying Cause of Death (1999-present), Multiple Cause of Death, Infant Deaths, and Provisional Mortality series. Researchers and analysts can group results by year, state, sex, age group, or ICD-10 chapter and apply any combination of filters in a single run.

Coverage: All 50 U.S. states plus D.C. - 1999 through the current provisional year. Over 22 ICD-10 disease chapters, 6 grouping dimensions, and 6 mortality database variants.

📋 What the CDC WONDER Mortality Scraper does

• Queries any of six CDC WONDER mortality databases via the official public API
• Groups results by year, state, sex, age group, or ICD-10 chapter in one request
• Filters by U.S. state (FIPS code), year range, and ICD-10 chapter simultaneously
• Returns deaths count, population, crude rate per 100,000, and age-adjusted rate with confidence intervals
• Applies maxItems cap so free users get a 10-record preview without wasting API quota
• Exports in any Apify-supported format: JSON, CSV, Excel, XML

💡 Why it matters: The CDC WONDER portal requires manual form submissions for every query. This actor turns any mortality query into an automated pipeline - schedule it weekly to track provisional data updates, or run it on-demand inside a Make or Zapier workflow.

📊 Data fields

Each record includes: additionalLabel, ageAdjustedRate, ageAdjustedRateLowerCI, ageAdjustedRateStdErr, ageAdjustedRateUpperCI, crudeRatePer100k, database, deaths, groupBy, groupCodes, groupLabels, icd10Filter, population, scrapedAt, sourceUrl, state, year, yearFrom, yearTo. These field names come straight from the actor's dataset schema, so what you see here is what lands in your dataset.

⚠️ Good to Know: the CDC suppresses any grouping with fewer than 10 deaths under its data-use restrictions. Suppressed cells return as null. The age-adjusted rate is flagged "Unreliable" by CDC when the underlying count is below 20; the Actor surfaces that as null for the rate field while keeping the raw death count.
