The statement is directly supported by authoritative and highly relevant primary data from the UK's Office for National Statistics, which confirms the youth unemployment rate at 16.1%. This figure is further corroborated by secondary sources such as OECD statistical releases and credible news coverage from Bloomberg, both of which cite official ONS data and provide context indicating it is the highest level since 2014. The historical unemployment trends presented in statistical summaries also align with the claim that no higher rate has occurred since 2014. There is no credible contradictory evidence from authoritative sources, and unofficial sources like social media posts reiterate the claim. The combination of multiple independent confirmations from authoritative and reliable outlets makes the probability of truth high.
