§ Mr. Wigley
asked the Secretary of State for Employment what are the latest available estimates of the average gross weekly earnings of full-time male and female, manual and non-manual workers in Gwynedd.
§ Mr. Booth:
Some limited information about average earnings in Gwynedd is available from the New Earnings Survey. The survey estimates for such small counties inevitably have relatively high sampling errors. In April 1974 average weekly earnings of the 114 full-time manual men in the sample whose pay for the survey reference period was not affected by absence were about £42.00, subject to a standard error of 3 per cent. The estimates for other groups had larger standard errors and so their publication could be misleading.
