§ Mr. Wigleyasked the Secretary of State for Wales what is the latest figure for the proportion of farms in Wales which generate 600 standard man-days of work; and how this compares with the proportion in 1966, 1971 and 1976.
§ Mr. Nicholas EdwardsFigures are readily available only for farms over and under 500 standard man-days for 1976 and 1979. The figures are not strictly comparable owing to changes in the standard man-day values of the various crops and livestock in 1968 and 1976 and in the minimum size of holdings included in the agricultural census between 1966, 1971 and 1976. The numbers of holdings covered in the censuses have also been affected by the statistical amalgamation of holdings while about 6,400 statistically insignificant holdings were excluded from 1968 onwards.
