Between June, 1964, and April, 1965, the latest date for which provisional information is available, the numbers of employees in employment in the construction industry in Great Britain are estimated as follows:
1964— (Thousands) June … … 1,614 July … … 1,614 August … … 1,623 September … … 1,622 October … … 1,623 November … … 1,627 December … … 1,620 1965— January … … 1,586 February … … 1,595 March … … 1,592 April … … 1,594 The introduction of the comprehensive National Insurance scheme in 1948 made considerable change to the coverage of the employment statistics and this break, together with changes of industrial classification, invalidate true comparison between current and pre-war employment figures. The following table shows the numbers of insured workpeople aged 16 to 64 years, estimated to have been in employment in Great Britain at July in 1937, 1938 and 1939 in building and decorating, public works contracting and electrical wiring and contracting:
