National Community Child Health Database (NCCHD)

The Population register of Welsh population National Community and Child Health is an individual level dataset which includes birth registration and monitoring of child health examinations and immunisations. The dataset contains all children born, resident or treated in Wales and born after 1987 to the present day. The dataset brings together data from local Child Health System databases which are held by NHS Trusts and used by them to administer child immunisation and health surveillance programmes. The dataset contains approximately 35,000 births per year and approximately 500,000 vaccinations per year.
