Mr. Robert Sheldon , pursuant to his reply [Official Report, 22 January 1979; Vol. 961, col. 27–31], gave the following information:It is convenient to answer these two questions together. The actual thresholds and the thresholds at 1945–46 prices are as follows: ------------- | | | | ------------- |1972–73|…|…| ------------- |1973–74|…|…| ------------- |1974–75|…|…| ------------- |1975–76|…|…| ------------- |1976–77|…|…| ------------- |1977–78|…|…| ------------- |1978–79|…|…| ------------- ------------- | | | | ------------- |1945–46|…|…| ------------- |1946–47|…|…| ------------- |1947–48|…|…| ------------- |1948–49|…|…| ------------- |1949–50|…|…| ------------- |1950–51|…|…| ------------- |1951–52|…|…| ------------- |1952–53|…|…| ------------- |1953–54|…|…| ------------- |1954–55|…|…| ------------- |1955–56|…|…| ------------- |1956–57|…|…| ------------- |1957–58|…|…| ------------- |1958–59|…|…| ------------- |1959–60|…|…| ------------- |1960–61|…|…| ------------- |1961–62|…|…| ------------- |1962–63|…|…| ------------- |1963–64|…|…| ------------- |1964–65|…|…| ------------- |1965–66|…|…| ------------- |1966–67|…|…| ------------- |1967–68|…|…| ------------- |1968–69|…|…| ------------- |1969–70|…|…| ------------- |1970–71|…|…| ------------- |1971–72|…|…| ------------- |1972–73|…|…| ------------- |1973–74|…|…| ------------- |1974–75|…|…| ------------- |1975–76|…|…| ------------- |1976–77|…|…| ------------- |1977–78|…|…| ------------- |1978–79|…|…| ------------- To convert the thresholds at 1945–46 prices to 1960–61 prices the figures should be multiplied by 1·686 but the relativities remain the same. The price index used is the General Index of Retail Prices (all items) and the index given in Table 2 of the publication of "The Internal Purchasing Power of the Pound", issued by the Central Statistical Office, with an estimate for 1945–46. The indices refer to financial years except for 1978–79, for which the October 1978 figure has been used. The thresholds for 1977–78 and 1978–79 include child benefit in the income of married couples where appropriate. The thresholds take account of earned income relief and family allowance deduction (clawback) where necessary.
