asked the Secretary of State for Employment what was the rate of geographical mobility of labour within the Uunited Kingdom in 1973 or the most recently available year; and how this compares with the rates 10 and 20 years previously.

There are no statistics available which measure the rate of geographical mobility of labour within the United Kingdom. Some information will be available in due course from the 1971 Census of Population showing the number of economically active persons who had moved across regional boundaries in Great Britain within one and five years of the census—i.e., whose addresses at the census date were in a different region from their addresses one and five years previously.
