New 2021 estimates indicate that 62.1 million women ages 18-64 have insurance coverage of preventive services, including birth control, without out-of-pocket costs as required by the Affordable Care Act (ACA). The ACA requires most health plans to cover a set of preventive services without out-of-pocket costs, including a specific group of preventive services for women, like birth control, well-woman visits, breast and cervical cancer screenings, and comprehensive lactation support and supplies. The new data mark a 3.4% decrease in the number of women covered by private health insurance since 2020, meaning nearly 2.2 million fewer women have private coverage this year. This factsheet includes state-by-state estimates as well as national estimates.
