Information is provided for workforce numbers, both payroll and non-payroll (contingent labour, including consultants), split between full-time equivalents (FTE) and headcount, with payroll staff numbers mapped to standard Civil Service grades.

For costs, payroll paybill information is broken down into its component parts, that is, salaries, allowances, employers pensions contributions etc, and non-payroll costs are split between costs for consultancy and those of other non-payroll workers.

Staffing numbers are as at the last day of the month for the reference month.

Cost information is that for the reference month. For baseline 2015/16 returns, staffing numbers are as at 31 March 2016, and paybill costs are for the financial year 2015/16.

Information for previous years is available on the National Archives.
