The data from the 22-month survey was deposited at the UK Data Archive along with the Birth Survey data as a composite dataset.
The 42-month survey and the 21-year sample survey are available from the Archive as separately documented datasets.
The 7-year survey was not deposited with the Archive at the time, because funding was not available for the necessary cleaning and documentation. But it is planned to clean, document and deposit this dataset in the near future.
The South-West Regional Survey was not deposited at the UK Data Archive. Users interested in the dataset should contact the User Support Group.
