DWP should liaise with other government departments to identify lessons for how it might take a more constructive approach to sharing data related to child poverty. DWP should write to us by June 2022 updating us on its progress (a) in working with the Office for National Statistics, Administrative Data UK and other government departments to develop new data matching and analysis programmes to understand better the causes and consequences of child income poverty; and (b) in addressing local authority concerns about the sharing of Universal Credit administrative data.
