UK Plans to Use Flawed Facial Age Estimation on Asylum Seekers Despite Known Bias Issues
The UK government plans to deploy facial age estimation AI at borders to assess asylum seekers' ages despite leaked government tests showing the technology regularly misidentifies children as adults and contains significant bias against Sub-Saharan Africans, the largest group of migrants affected by age assessments.

The British government plans to introduce facial age estimation (FAE) technology at its borders starting next year to determine the age of asylum seekers, marking what is believed to be the first governmental use of such AI-powered systems for this purpose. The technology scans faces and estimates age to assist with age verification when asylum seekers lack official documentation. However, an investigation by WIRED, Lighthouse Reports, and The Independent has obtained leaked internal government documents revealing significant technical failures and bias in the systems being considered for deployment.
According to the leaked Home Office report, the FAE systems tested regularly misclassify children as adults and contain serious bias problems that disproportionately affect the largest group of migrants entering the UK. Testing of the best-performing algorithm among seven candidates showed that for female Sub-Saharan Africans, age estimates were off by an average of 4.6 years—meaning a 13-year-old could be assessed as an 18-year-old adult. Sub-Saharan Africans represent the largest cohort of migrants entering the UK via small boat crossings and received the highest number of age assessments in 2025.
The consequences of misclassification are severe. Children incorrectly identified as adults can lose legal protections and be placed in adult detention facilities, fundamentally altering their access to safeguarding and care. The investigation highlights a troubling trend of governments worldwide, including the second Trump administration, increasingly adopting anti-migrant policies while deploying surveillance and biometric technologies against vulnerable populations with limited transparency or opportunity to challenge decisions made by these systems.
The use of FAE in border enforcement represents a broader pattern of age verification technologies expanding from digital platforms—such as social media bans in Australia and adult content restrictions across US states—into high-stakes real-world applications affecting fundamental freedoms and legal status. The leaked documents raise critical questions about whether such technology should be deployed in scenarios where errors carry life-altering consequences for minors and vulnerable migrants.
Why This Matters
This development directly threatens the safety and legal status of vulnerable migrant children. When AI systems misclassify minors as adults—potentially by 4+ years—these children lose critical legal protections, face adult detention, and have their asylum claims jeopardized. The UK's decision to deploy a known-flawed system despite internal evidence of bias sets a dangerous precedent for governments worldwide, normalizing high-stakes decisions about fundamental rights being made by opaque, error-prone algorithms. Readers should understand that this affects real children's access to safeguarding, and highlights the urgent need for regulatory guardrails on AI deployment in immigration enforcement.
