Methodology
Methodology notes
[Denominator notes] The Guttmacher Institute periodically (approximately every 2 years) estimates the number of women in need of publicly supported contraceptive services and supplies, as well as the number of women who receive public-sector contraceptive services in the United States. Estimates of women in need of contraceptive services are based on population estimates (by age and race/ethnicity) from the U.S. Census Bureau; poverty and marital status data form the American Community Survey (ACS), and characteristics of women from the National Survey of Family Growth (NSFG). Detailed methodology for making these estimates has been published. Women are defined as in need of contraceptive services and supplies during a given year if they are aged 13-44, have ever had sexual intercourse, neither they nor their partners have been sterilized or are infecund for any reason, and they are neither intentionally pregnant nor trying to get pregnant over the entire year. Women are defined as in need of publicly supported contraceptive services if they are in need of contraceptive services and are either aged 20 or older with a family income below 250% of the federal poverty level, or are younger than age 20. [Numerator notes] Estimates of the number of women receiving publicly supported contraceptive services are based on data from Guttmacher's Census of Publicly Funded Family Planning Clinics and from the NSFG. Additional information on the methodology for collecting these data has been published.
