Perceived
Public perception of sexual assault on campuses varies enormously by country and cultural context. In the US, a series of high-profile cases, the AAU 2019 campus climate survey, and the Title IX regulatory framework have raised awareness to levels not seen in comparable educational systems. In other high-income countries — Australia, the UK, Germany — awareness is lower despite comparably measured prevalence. Globally, the risk is systematically underestimated: women in higher education who are assaulted most often do not report to authorities, and many frame the experience in ways that diverge from legal definitions of assault. The multi- year exposure of a university degree means cumulative probability is substantially higher than annual rates would suggest.

17.5 in 100 women students report sexual assault during higher education

Show derivation
Steele et al. 2024 (Trauma, Violence, & Abuse) meta-analysis of 131 articles across 21 countries: 17.5% of women students report sexual assault during higher education (95% CI 15.3–20.0; US-dominated, ~73% of articles). US data (AAU 2019, n=181,752): 25.9% of undergrad women report nonconsensual sexual contact since enrollment; 16.2% report nonconsensual penetration. The headline (0.175) uses the Steele et al. 2024 meta-analysis as the primary source. The US AAU figure (0.26) is cited for comparison. Australia 2021 National Student Safety Survey (Universities Australia / Social Research Centre): 4.5% sexual assault, 16.1% sexual harassment since starting university (all students). Scope is subgroup_lifetime (women enrolled in higher education, study period cumulative). Definitional heterogeneity is substantial; see caveats. Low (0.05): narrower definitions (penetration only, studies with lower recall). High (0.30): US-specific broad definitions including all nonconsensual sexual contact.

Definitional heterogeneity is the primary methodological challenge. The Steele et al. 2024 meta-analysis pools studies using widely varying definitions: some include verbal coercion, some require physical force, some cover any nonconsensual contact, and some are limited to penetration. The 17.5% headline is a pooled average across these heterogeneous studies, and is heavily US-weighted (~73% of the 131 included articles came from the United States), so it is not a representative global average. The US AAU figure (25.9% contact, 16.2% penetration for undergraduate women) reflects broader definitions than many international studies. Direct cross-country comparison requires care: a 4.5% rate in Australia (all students, narrower definition) and 17.5% for women may reflect definitional and population-base variation rather than prevalence differences. Reporting rates are very low across all settings (typically 5–20%), meaning these figures come from research surveys, not crime statistics. Study period varies (1 year vs. entire degree); the cumulative-over-degree framing used in most US studies produces higher rates than annual estimates.

A 2024 meta-analysis in Trauma, Violence, & Abuse (131 articles across 21 countries, though roughly three-quarters of the studies were from the United States) found that 17.5% of women students report sexual assault during higher education — roughly 1 in 6, with a 95% confidence interval of 15.3–20.0%. The US-specific data from the AAU 2019 campus climate survey of 181,752 students across 33 research universities found a higher figure: 25.9% of undergraduate women reported nonconsensual sexual contact since enrollment, and 16.2% reported nonconsensual penetration. Australia’s 2021 National Student Safety Survey found that 4.5% of all students were sexually assaulted and 16.1% sexually harassed since starting university, under a narrower definition. The range across these studies reflects primarily definitional and population-base variation, not substantive differences in experience.
The gap between measured prevalence and reported crime statistics is large everywhere. In campus surveys, typically 5–20% of women who report experiencing sexual assault describe having formally reported it to the university or police. Non-reporting is driven by multiple factors: uncertainty about whether the experience met the legal threshold, familiarity with the perpetrator (who is most often a peer or acquaintance, not a stranger), concerns about social consequences, and distrust of institutional response. This gap means that crime statistics dramatically understate the campus sexual assault landscape, and that prevention and institutional response operate with an incomplete picture of incidence.
The “red zone” — the first eight weeks of the first academic year — is consistently identified as a period of disproportionately elevated risk across US campus studies. Incoming students are navigating unfamiliar social environments, often without established friend networks, frequently in settings involving alcohol, and without prior experience reading risk cues in the specific social contexts of their campus. This peak dissipates over the course of the first year as students develop orientation to their environment. The implication is that prevention efforts with the highest marginal return are those targeting incoming students before and immediately after arrival.

About 1 in 6 women students globally report sexual assault during higher education, rising to 1 in 4 in US undergraduate surveys. The native figure is 17.5 per 100 women students worldwide.

- Steele et al. 2024 (Trauma, Violence, & Abuse) — systematic review with meta-analyses. 131 articles from 21 countries; the meta-analyzed prevalence of sexual assault was 17.5% for women students (95% CI 15.3–20.0). The 17.5% pooled prevalence is the native rate. Normalized directly: 0.175, scope = subgroup_lifetime (women students, study-period cumulative). No conversion needed as this is already expressed as a cumulative probability over the higher education period. (Note: the 17.5% figure is dominated by US studies — 95 of 131 articles, ~73% — so the global generalization is limited; see caveats.)

The 25.9% "nonconsensual sexual contact" figure and 16.2% penetration figure (both undergraduate-women rates) are the US-specific anchor. The 13% figure reported by AAU is the ALL-STUDENTS nonconsensual-contact rate, not the undergraduate- women penetration rate. AAU universities are selective research institutions, possibly not representative of all US colleges; the figures are used here as the US-specific corroboration for the global meta-analysis headline.

- 2021 National Student Safety Survey — national report, commissioned by Universities Australia and conducted by the Social Research Centre (NOT the Australian Human Rights Commission, which ran the earlier 2016 survey). n=43,819 students across 39 universities. The 4.5% sexual assault rate is an ALL-STUDENT figure (not women-specific) under a narrower Australian definition, providing a lower-bound anchor; 16.1% is the all-student harassment rate. The narrower definition and broader denominator explain why this figure is lower than the global meta or the US AAU undergraduate-women rate; all are likely measuring the same phenomenon with different definitional inclusion thresholds and population bases.
