The proportion of UK food consumption that was produced in the UK was 63% in 1994 and 53% in 2004. The detailed trade data used in this calculation is not available before 1988.
The latest available figures for 2013 give the proportion as 53%.
An alternative and frequently used measure is the UK production to supply ratio for indigenous type food. This compares total national production with production excluding exports and including imports. It is not directly comparable with the domestic food consumption proportion above because it includes food that the UK exported which could have been consumed domestically. The UK production to supply ratio for indigenous type food for 2013 was 73%. “Indigenous type food” refers to types which can be produced in the UK on a commercially viable basis.
A time series of the production to supply ratio is also available in table 14.1 and chart 14.5 in “Agriculture in the United Kingdom”.
