    "description": "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.\n",

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.\n"

  "caveats": "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.\n",
