Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, how many of the streams of data collected by his Department are (a) used by the Department, (b) read by how many people and (c) unused or unread.

I have interpreted the question to be asking for the number of datasets compiled by the department. This information is not currently available and could only be provided at disproportionate cost.
