Short answer: there's no "normal" body count. National surveys find a huge spread, from people with no partners at all to people with dozens or more. The middle of that spread is lower than social media might suggest, though. Below are the most reliable figures we could find, all from large national surveys, with sources linked.
Average body count at a glance
- UK, all adults aged 16–74 (Natsal-3, 2010–2012): men reported a median of 6 female partners in their lifetime, and women a median of 4 male partners [1].
- US, sexually experienced adults aged 25–49 (NSFG 2015–2019): the median number of opposite-sex partners was 6.3 for men and 4.3 for women [2].
- 15 or more partners: in the same US survey, 28.3% of men and 12.9% of women aged 25–49 reported 15 or more opposite-sex partners [2].
A median is the middle person: half of people reported fewer, half reported more. It's the best single number for "typical" here, because a small group with very high numbers drags the mean (the ordinary average) upwards. That's why the means in the UK table below are roughly double the medians.
Average body count by age: UK (Natsal-3)
Natsal-3 interviewed 15,162 people aged 16–74 across Britain between 2010 and 2012 [1]. It uses a random probability sample weighted to match the population, and at the time of writing it's the most recent published national survey we could find that reports partner numbers for every age band. Initial results from its successor, Natsal-4 (fieldwork 2022–2024), are due at the end of November 2026 [5], and we'll update this page when they're out.
| Age | Men: median | Men: mean | Women: median | Women: mean |
|---|---|---|---|---|
| 16–24 | 3 | 6.5 | 3 | 5.2 |
| 25–34 | 6 | 13.7 | 5 | 8.9 |
| 35–44 | 8 | 14.3 | 5 | 8.5 |
| 45–54 | 8 | 17.5 | 4 | 6.8 |
| 55–64 | 5 | 20.1 | 3 | 6.1 |
| 65–74 | 4 | 12.1 | 2 | 6.3 |
| All, 16–74 | 6 | 14.1 | 4 | 7.1 |
Source: Mercer et al., The Lancet 2013, Tables 2 and 3 [1]. Men's figures are female partners and women's figures are male partners. Everyone surveyed is included, including people with no partners yet (19.8% of 16–24-year-olds of both sexes). Same-sex partners are reported separately in the study and are not in these numbers.
Two things stand out. First, the numbers climb through your 20s and 30s, then the older age groups report fewer. Because this is a snapshot of different generations rather than the same people followed over time, that pattern likely reflects generational differences too, not just people "stopping". Second, the gap between the median and the mean shows how skewed the data is. A few people with very high counts pull the average up.
Average body count by age: US (NSFG)
The CDC's National Survey of Family Growth (NSFG) is the main US source. The most recent CDC report we could find with medians for each individual age band covers 2006–2008 [3]. The newer CDC key statistics (2015–2019, above) give a single figure for ages 25–49 [2].
| Age | Women: median | Men: median |
|---|---|---|
| 15–19 | 1.4 | 1.8 |
| 20–24 | 2.6 | 4.1 |
| 25–29 | 3.6 | 5.7 |
| 30–34 | 4.2 | 6.4 |
| 35–39 | 3.5 | 6.2 |
| 40–44 | 3.4 | 6.4 |
| All, 15–44 | 3.2 | 5.1 |
Source: National Health Statistics Reports No. 36 (2011), Tables 3 and 4 [3]. "Partner" means someone you've had vaginal, oral or anal sex with. Medians exclude people who have never had sex with an opposite-sex partner. NCHS reports medians to one decimal place.
Why men report more partners than women
In a closed population, men's and women's average number of opposite-sex partners should come out roughly equal, yet surveys almost always show men reporting more. A 2019 analysis of Natsal-3 found men reported a mean of 14.14 lifetime partners and women 7.12 [4]. Capping extreme answers, accounting for whether people counted or estimated, and adjusting for attitudes together may explain almost two-thirds of that gap. In other words, a lot of it comes down to how people answer, not what they actually did.
Caveats: read this before comparing yourself
- It's all self-reported. People round, estimate and sometimes shade their answers towards what feels socially acceptable, in both directions.
- Definitions differ. Each survey decides what a "partner" is. Your own definition might be narrower or wider. Try our body count calculator to see how much the definition changes the number.
- Mostly opposite-sex partners. These headline tables count opposite-sex partners only, so they say little about queer people's experiences.
- The data has some age on it. Natsal-3 was collected in 2010–2012 and the NSFG age table in 2006–2008. They're still the best published age breakdowns we could verify, but today's 20-somethings weren't the ones surveyed.
- There's no "normal". A wide range is completely ordinary. Your number says nothing about your worth, your health or how good a partner you are.

Frequently asked questions
What is the average body count?
In Britain's Natsal-3 survey (2010–2012), the median number of lifetime opposite-sex partners for adults aged 16–74 was 6 for men and 4 for women. In the US NSFG (2015–2019), the median for sexually experienced adults aged 25–49 was 6.3 for men and 4.3 for women.
What is the average body count for 16–24 year olds?
In Natsal-3, the median for 16–24-year-olds in Britain was 3 lifetime opposite-sex partners for both men and women. That figure includes the roughly 1 in 5 in that age group who hadn't had a partner yet.
What is a normal body count?
There isn't one. Surveys show a very wide spread, from zero to dozens of partners, and the numbers vary with age, generation, sex and how "partner" is defined. Any number is normal.
Why is the mean so much higher than the median?
A small number of people report very high partner counts, which pulls the mean (the ordinary average) up. The median, the middle person, is a better guide to what's typical.
Why do men report more sexual partners than women?
Research on Natsal-3 suggests much of the gap comes from how people answer: a few very high outliers, differences in whether people count or estimate, and attitudes that shape what people feel comfortable reporting.
Is this data up to date?
These are the most recent published national figures we could verify. The age-by-age tables come from surveys carried out in 2010–2012 (UK) and 2006–2008 (US), and the newest US figure covers 2015–2019. We'll update this page when newer breakdowns are published.
