§ Mr. Gouldasked the Secretary of State for Trade and Industry whether he will publish in the Official Report a table showing for the period since 1953 the effect on the increase in export and import unit values of each move in the base year for statistical purposes; and what was the corresponding effect in the case of wholesale prices.
§ Mr. ChannonThe information is as follows:

Notes to the tables
Unit Value Indices
The figures in brackets are derived from the index numbers currently published on 1980=100 but compiled using the weights of previous base years. Differences between the bracketed figures and those for the relevant base period are due to revisions and changes to coverage; not to the effect of re-basing.
Producer Price Index
1 1949=100 data is for manufactured products other than fuel, food and tobacco; on the 1948 SIC with base year 1948.
2 1954=100 data is on the 1958 SIC with base year 1954.
3 1963=100 data is on the 1958 SIC with base year 1963.
4 1970 = 100 data is on the 1968 SIC with base year 1968.
5 1975=100 data is on the 1968 SIC with base year 1974.
6 1980=100 data is on both (a) 1968 SIC and (b) 1980 SIC. The effect of the change in base year can be seen by comparing (a) with the column for 1975=100.
