This paper summarises findings from an analysis of integrated administrative data seeking to identify the characteristics of young people aged 15 to 24 who are most at risk of poor longterm outcomes. The research is part of a broader 'social investment approach' by government agencies seeking to target services more effectively towards those most at need and reflects the recognition that such an approach requires better evidence about who these at-risk groups are. The analysis identifies those characteristics in the administrative data that are most predictive of a range of future poor outcomes and how this changes over the course of a young person's entry into adulthood and identifies groups of young people at particular risk at different ages.

The analytical paper is being released alongside an A3 document which summarises the results of the analysis, and a set of detailed excel tables. See links below.
