Nearly one in five women (18.9%) and one in seven men (14.8%) globally experience sexual violence before the age of 18 years, estimates a new analysis by international researchers, which found Australia and New Zealand are experiencing rates above the global average. The study, which also identified significant region- and country-level differences, found Australia and New Zealand to be experiencing higher rates than most other high income countries, with over a quarter of women (27.8% in Australia, 28.8% in New Zealand), one in six Australian men (16.9%) and one in five Kiwi men (21.8%) estimated to experience sexual violence before age 18.

The Lancet: Nearly one in five women and one in seven men globally experienced sexual violence before the age of 18 years, systematic review estimates

Nearly one in five women (18.9%) and one in seven men (14.8%) globally experienced sexual violence before the age of 18 years, estimates a new analysis published in The Lancet

The study also identified significant region and country-level differences in the rate of sexual violence in under 18’s, with the USA estimates being 27.5% of women and 16.1% of men; UK estimates being 24.4% of women and 16.5% of men, and estimates for India being 30.8% of women and 13.5% of men. 

Sexual violence against children (SVAC) is a critical public health and human rights issue, contributing to severe long-term consequences for those affected. Survivors face heightened risks of major depressive disorder, anxiety, substance use, long-term health conditions such as asthma and sexually transmitted infections, and indirect impacts such as limited individual development, hindering both educational attainment and economic achievement. Accurate global estimates of SVAC rates are important for targeted prevention and advocacy efforts, yet existing studies present estimates for a limited number of countries and are hindered by data sparsity and measurement challenges. 

The current study is one of the first to estimate the prevalence of SVAC for 204 countries by age and sex, from 1990 to 2023. The study found the highest average rates of sexual violence were recorded in south Asia for women, with rates ranging from 9.3% in Bangladesh to 30.8% in India, while sub-Saharan Africa had the highest rates among men, varying from 7.9% in Zimbabwe to 28.3% in Côte d'Ivoire. The authors highlight the difficulty in distinguishing whether these differences in rates of sexual violence between countries and regions are due to true differences in prevalence or are instead driven by different levels of reporting. 

The authors say their results highlight the need to develop routine surveillance of SVAC, and for health systems and societies to put more services and systems in place to support survivors of SVAC for the rest of their lives. The authors call for governmental, non-governmental organisations, and society more widely, to urgently and significantly commit more resources to supporting survivors and to creating childhoods free of sexual violence.

SVAC rates of 27.8% in Australia for women and 16.2% for men is among the highest prevalences of SVAC listed globally. These comparatively high rates may be because Australia has culture where it is relatively more socially acceptable to report sexual violence than in perhaps other places of the world. However, these global figures are probably still an underestimation of the actual prevalence of SAVC, given that it is still difficult to disclose and the limited definition of sexual violence being used in this study. It might align with international frameworks but does not include online abuse prevalent in today’s technological age. Such online abuse includes the production and distribution of sexually explicit deepfakes without consent or coercing young people to produce sexually explicit material for money (sextortion). These findings are exceptionally significant, as they allow a basis from which to track prevention efforts. However, these newer forms of sexual violence arising in the online space are worthy of attention and research if we are to prevent SVAC. These statistics for Australia may mean that more reports of SVAC are coming out into the open – that’s good news. But now that we know where we stand, let’s work on stopping sexual violence before it starts.

This study highlights the persistent and urgent problem of child sexual abuse. While international comparisons are always challenging given variations in data collection, the findings reported in this article are consistent with high quality surveys from Aotearoa New Zealand. Findings support NZ work going back as far as the 1990s, indicating that approximately 1 in 4 girls, and approximately 1 in 10 boys experience child sexual abuse.

Child sexual abuse has a serious and significant impact on those who experience it. However, there are also ripple effects. Child sexual abuse damages families and communities. Recent evidence from the Royal Inquiry into Abuse in State Care has shown the long-term impact of child sexual abuse.

What matters now is what we do next.

Information such as that presented in this study should not be allowed to sit on a shelf somewhere. We need to use it as a catalyst for investment. We need to take a strategic approach to addressing all types of family and sexual violence. It is no longer sufficient to take a piecemeal approach hoping that individual parts of the system will eventually join up.

Such an approach will require building a prevention infrastructure and engaging communities.

While such an approach might sound costly, we need to recognize that we are already paying for these persistent problems. We are paying with poor educational outcomes, costly health services, and overloaded criminal justice systems. Investing in evidence-based prevention is a longer-term approach to building an economically productive, healthier society. It will also help us tackle the reprehensible problem of child sexual abuse that we have swept under the carpet for too long.

This study disappointingly shows that sexual violence against children remains a significant and widespread public health issue with little change in global prevalence over the last 30 years.  The personal and societal burden of SVAC is substantial with well-established associations with adverse outcomes in multiple life domains.

Worryingly this study finds that prevalence of sexual violence against children among Aotearoa New Zealand women remains high but also reports high prevalence in men. What is not seen in this work is the prevalence among transgender, gender fluid, non-binary or intersex individuals, groups known to be at risk for sexual violence.

Comprehensive relationship and sexuality education is an important aspect of prevention, and it is vital New Zealand looks to the best available evidence to support development of guidance following the removal of the 2020 guidelines. The study identified a substantial increase in experiences of sexual violence from age 12 -18, underscoring the importance of comprehensive education for this age group.

It is clear from this research there remains much work required globally and in New Zealand in efforts to prevent sexual violence against children, and the need for safe and effective support for those who have experienced it.  With such a high prevalence in New Zealand and given the long-term impact on survivors it is critical that addressing sexual violence against children is a high priority.

This landmark study offers a powerful and sobering picture of sexual violence against children, both globally and in Australia. It estimates that 27.8% of females and 16.9% of males in Australia have experienced sexual violence before the age of 18 — among the highest prevalence rates in the world. While there are methodological challenges in making direct international comparisons, the findings make it clear that this is an entrenched and ongoing issue in Australia.

It is important to remember that these numbers reflect the lived experiences of thousands of Australians, many of whom carry the impacts of trauma across their lives, often in silence. Sexual violence against children continues to happen now in homes, schools, institutions, and communities. It is a complex issue that is driven by a range of individual, social, cultural, and systemic factors,

A coordinated, national and multisectoral response is urgently needed. This includes delivering primary prevention activities that are appropriately targeted for a range of audiences, strengthening the capacity of adults and professionals to identify and respond to abuse, and ensuring victim-survivors have access to timely, trauma-informed care. Crucially, our response must be supported by serious, sustained investment and political will — across education, health, justice, and child protection systems.

A global dataset of sexual violence against children, here defined as below the age of 18, has never been attempted to this degree (from 1990-2023) and paints a sobering picture for Australia.

Almost one in three Australian girls (27.8%) and one in six boys (16.9%) have been sexually abused before the age of 18. This is not a small number and places Australia among the world's worst offenders, close to India, which is the world's worst at 30.8 % of girls and 13.5% of boys. (As a side note, contiguous Bangladesh is one of the least so it's cultural, not genetic).

It should be remembered this is sexual violence. Global datasets help put in context the scope of the problem and highlight trends in data. Sadly, the authors find the data trends to be fairly stable, which means this is a stable cultural characteristic. For example, data trends show that Australian femicide is falling across years, though we still have a national crisis, whereas this data on child sexual assault shows no such trend.

Years ago another set of researchers found that Japan was one of the highest producers of child pornography in the 1990s but that Australia was one of the world's highest consumers. This also accords with some of the worst crimes committed against children where Australians have been involved in child sex tourism. It also accords with the widespread predation on Australian children by religious orders.

This is victim-level data rather than reported to police, which means it's more accurate but still likely an underestimate. For additional context, Australia's predation on its own children is fully 47% higher than the world average for girls. The fact that it's only 14% higher for boys means that it is very much gendered, reflecting a nation even more likely to see its girls as sexual prey.

This is a national disgrace and should be investigated by the Albanese government.

A new article, just released by the Lancet Commission is one of the first studies on Sexual Violence against Children (SVAC), with data from 204 countries by age and sex. The study has documented confronting figures - 18.9% of adolescent young women and 14.8 % of adolescent young men under 18 years globally experienced sexual violence. The article reports that 7.7% of the 16,786 females globally had experienced sexual violence before the age of 12 years with this increasing to 67.3% before the age of 18 years.  

The highest average rates for sexual violence against young women were recorded in South Asia and for young men in Africa. There were also stark and notable regional, country and geographic differences with estimates for India being 30.8% of young women and 13.5% of young men and 27.5% of young women and 16.1% of young men for the USA.

SVAC is a critical human rights, public health, social, and community issue with significant long-term impacts. Survivors face a lifetime of health conditions with major psychosocial and mental health impacts, including depression, anxiety, substance abuse, and STIs and chronic conditions. The authors state that SVAC is often under-reported, so actual figures may be much higher and there is a dire need for resources and funding to develop health system support for surveillance in all countries for accurate estimation of SVAC so that targeted interventions and services are provided to survivors throughout their life and globally generations of children can be protected.
