HC Deb 29 June 1978 vol 952 c642W
Mr. Nicholas Winterton

asked the Secretary of State for Employment what process is used to adjust seasonally the figures his Department publishes on the rate of unemployment.

Mr. Golding

The process used is technically known as the Census Method II Variant X-11, additive version. An article describing in some detail the methodology will be published in the Department of Employment Gazette shortly.
