It's one of those questions everyone wonders about but few discuss openly. According to the CDC's National Survey of Family Growth, the number of lifetime opposite-sex sexual partners for American adults varies by age and gender. This calculator uses that federal survey data to show you exactly where you fall.
The NSFG is conducted by the National Center for Health Statistics, part of the Centers for Disease Control and Prevention. The 2022–2023 cycle collected responses from 5,586 women and 4,371 men aged 15–49 across the United States. Responses are weighted to produce nationally representative estimates. The lifetime partner count (LIFPRTNR) covers opposite-sex sexual partners and is top-coded at 50 in the public-use data file — meaning anyone who reported 50 or more partners is grouped together. This calculator covers ages 18–49.
Your result tells you what percentage of people in your demographic reported fewer lifetime partners than you. If your result says 75%, that means you've had more partners than 75 out of every 100 people your age and gender in the United States. There's no "right" number — this is purely informational, built on federally collected data to satisfy a very human curiosity.
