§ Mr. WebbTo ask the Secretary of State for Social Security if he will provide the estimates of the proportion of the population in each county with income below 60 per cent. of median income which underlay Figure 3.6 of his Department's report, "Households Below Average Income". [131749]
§ Mr. Bayley[holding answer 21 July 2000]Figure 3.6 presents information for counties ranked into five equal sized groups. Although the underlying data were used in the production of the maps, DSS statisticians advise that precise results for individual counties are not robust enough to be presented separately. Results for individual counties are affected by sampling error and response biases and by the fact that the Family Resources Survey, from which HBAI estimates are drawn, has a sample stratified at regional, not county, level.
