The data behind child abuse

Most sexual abuse isn’t reported, detected or prosecuted. It’s a crime that is usually only witnessed by the abuser and the victim.

million people

One in five adults aged 18 to 74 years experienced at least one form of child abuse, whether emotional abuse, physical abuse, sexual abuse, or witnessing domestic violence or abuse, before the age of 16 years (8.5 million people), according to the Crime Survey for England and Wales (CSEW)

In addition, an estimated 1 in 100 adults aged 18 to 74 years experienced physical neglect before the age of 16 years (481,000 people); this includes not being taken care of or not having enough food, shelter or clothing, but it does not cover all types of neglect.

An estimated 3.1 million adults aged 18 to 74 years were victims of sexual abuse before the age of 16 years; this includes abuse by both adult and child perpetrators.

Prevalence was higher for females than males for each type of abuse, with the exception of physical abuse where there was no difference.

Many cases of child abuse remain hidden; around one in seven adults who called the National Association for People Abused in Childhood’s (NAPAC’s) helpline had not told anyone about their abuse before.

It is important that the hidden nature of childhood abuse is addressed through better research and data. A good example of this was the Office of National Statistics (ONS) publishing its inaugural report solely about child abuse on 14 January 2020. The report provides an overview of child abuse in England and Wales and for the first time brings together a range of different data sources from across government and the voluntary sector, including anonymised data from NAPAC’s support line service. The full report can be found here – ONS report Child abuse in England and Wales: January 2020

NAPAC has provided direct telephone or email support to over 60,000 survivors.

In 2023 NAPAC answered 7,480 calls on our support line and replied to 2,812 support emails.

NAPAC has also seen significant positive changes in our website demographics. The proportion of website users aged 18 to 24 more than doubled between 2020 and 2022, and over the past 5 years there has been a 17% increase in the number of men accessing our website.

Our own data tells us that from the moment the abuse stops, on average it takes a survivor 22 years to disclose their abuse. The sustained increase in young website users means that many are starting to speak out earlier, beginning the recovery process sooner and moving forward with their lives.

The positive impact of survivor-led and survivor-centred initiatives like Everyone’s Invited and the Brave movement are helping more survivors access support, and recognise that they are not alone.

Over the past five years, NAPAC has evolved to become one of the UK’s leading trainers in trauma-informed practice and survivor support. We have trained thousands of professionals across a variety of industries, including the education sector, policing, nursing, mental health units, third sector organisations, local authorities and law firms. You can view some of our success stories here.

Our self-directed online training modules currently average a feedback score of 4.5 out of 5, whilst our facilitated training, delivered in person and online, averages a feedback score of 4.9 out of 5.

The Centre of Expertise on Child Sexual Abuse (CSA) has been established to help bring about significant and system-wide change in how child sexual abuse is responded to locally and nationally. More information can be found at its website here – CSA Centre

It is estimated that only one in eight victims of sexual abuse come to the attention of statutory authorities (Children’s Commissioner 2015).

One in three children and young people are exposed to at least one potentially traumatic event by the time they are 18. (UK Trauma Council)

Traumatic life experiences can have a significant impact on people’s lives, increasing the risk of poorer physical and mental health and poorer social, educational and criminal justice outcomes. Trauma informed systems can have better outcomes for people affected by trauma (NHS Education for Scotland, May 2017).

The 2021 Home office report into the economic and social cost of contact child sexual abuse estimates the financial and non-financial (monetised) lifetime cost relating to all victims who began to experience, or continued to experience, contact CSA in England and Wales in the year ending 31st March 2019 to be at least £10.1 billion.

Child sexual abuse costs the UK £3.2bn a year (Radford)

One in three children sexually abused by an adult did not tell anyone (Radford, 2011).

Some children did disclose abuse when still young but were not heard or no action was taken (Allnock and Miller, 2013; Lampard and Marsden, 2015).
1 %
Over 90% of sexually abused children were abused by someone they knew (Radford, 2011).
There are an estimated minimum of 11 million adult survivors of contact and non-contact child sexual abuse in the UK (Radford et al).
There was a 106% increase in child cruelty and neglect offences in England between April 2017 and March 2023. (NSPCC data)

Between 2019 and 2024, over 1,500 survivors have trusted NAPAC with their first disclosure.

NAPAC receives hundreds of contacts per week from adult survivors of child abuse.
