Methodology
How we estimate the gap
A modeled estimate from public data only. It is not a count of patients and contains no patient information.
missing = adults 50 to 80 × county smoking rate × national eligibility factor × (1 − state screening rate)
- Adults 50 to 80: U.S. Census Bureau, Population Estimates, Vintage 2025
- Smoking: CDC PLACES 2025 release (Kentucky and Pennsylvania: 2024 release)
- Eligibility: USPSTF 2021 criteria, scaled to about 14.5 million eligible adults nationally
- Screening rates: American Lung Association, State of Lung Cancer 2025
- Who is missing: Census population estimates (age) and American Community Survey 2020 to 2024 (language)
- Screening activity: CMS Medicare fee-for-service claims for low-dose CT (CPT 71271), 2024, by provider location
- Lung cancer cases and deaths: National Cancer Institute and CDC, State Cancer Profiles (incidence 2019 to 2023, deaths 2020 to 2024)
- Smoking history: University of Minnesota National Lung Cancer Screening Estimates (Haynes 2026)
