We monitor the number of children entering the care system on an ongoing basis and information showing the change in the number of children entering the care system for the period since 2010 is provided in the table attached.
Further breakdowns of children who started to be looked after can be found in Table C1 of the statistical first release 'Children Looked After in England including Adoption: 2016 to 2017' at: https://www.gov.uk/government/statistics/children-looked-after-in-england-including-adoption-2016-to-2017.
We set out our vision for delivering excellent children’s social care in ‘Putting Children First’. This outlines our reform programme which seeks to: improve the quality of social work practice; create systems and environments where great social work can flourish; promote learning and multi-agency working where all involved in supporting children and families can work together; and support children who both enter and leave the care system. The reforms are designed to ensure that all vulnerable children and families receive the highest-quality care and support. We have invested over £200 million through the Innovation Programme to test and develop better practice, including testing approaches to help vulnerable children to remain safely at home.
