Low Incomes Miss Richardson asked the Chancellor of the Exchequer how many (a) single people without children, (b) married men without children, (c) married men with children, (d) one-parent families, and (e) working wives were below the tax threshold at the latest available date. Mr. Denzil Davies Information is not directly available as to the numbers below the tax thresholds in the population categories specified.But it may be helpful to have estimates, on a slightly different definition, of the total population to compare with the number paying tax in these categories. Population estimates and a special analysis of the general household survey suggest that the total population in each specified category was approximately: ---------------------------------------- | | ---------------------------------------- |Single persons without children | ---------------------------------------- |Married men without dependent children| ---------------------------------------- |Married men with dependent children | ---------------------------------------- |One-parent families | ---------------------------------------- |Working wives | ---------------------------------------- These figures are provisional.----------------------------------------------- | | | | | | | ----------------------------------------------- |(a) Single persons without children|…|…|…|…|…| ----------------------------------------------- |(b) Married men without children |…|…|…|…|…| ----------------------------------------------- |(c) Married men with children |…|…|…|…|…| ----------------------------------------------- |(d) One-parent families |…|…|…|…|…| ----------------------------------------------- |(e) Working wives |…|…|…|…|…| ----------------------------------------------- The latest available firm information, for 1975–76, is based on the Inland Revenue's survey of personal incomes. The figures for 1978–79 are estimates. The number of working wives includes in each year about 200,000 wives whose husbands are not taxpayers and are not included in ( b) or ( c).
