From the 2019 National Health Interview Survey:
Numerator:

Methodology notes
Data include women who have had a mammogram within the last 2 years. Healthy People 2030 uses the U.S. Preventive Services Task Force (USPSTF) recommendations to measure this objective, and the current USPSTF recommendation includes biennial mammography for women aged 50 to 74 years (Grade B), with an additional recommendation that starting biennial mammography for women 40 to 49 years should be an individual decision considering patient context, including a patient's beliefs regarding possible benefits and harms (Grade C).
The denominator does not include respondents who reported ever having breast cancer.

History
- Revised.
In 2022, due to the 2019 NHIS redesign, the baseline was revised from 72.8% in 2018 to 76.4% in 2019. The target was revised from 77.1% to 80.5% using the original target setting method.
- Revised.
In 2023, the denominator was revised to exclude women with a history of breast cancer. As a result, the baseline was revised from 76.4% to 76.2% in 2019 and the target was revised from 80.5% to 80.3%.
- Revised.
In 2024, the following categories were recalculated with the use of a newer variable: Never married, American Indian or Alaska Native only, Native Hawaiian or Other Pacific Islander only, 2 or more races only, Not Hispanic or Latino American Indian or Alaska Native only, Not Hispanic or Latino Native Hawaiian or Other Pacific Islander only, Not Hispanic or Latino 2 or more races only. Estimates from data year 2022 or earlier may vary slightly from estimates previously reported. The baseline, baseline year and target were not affected.
