This article presents an input–output table for England and Wales for the year 1688 which is based on the extensive dataset compiled by Gregory King in the 1690s, together with other contemporary and modern material relating to the end of the seventeenth century. As well as showing the inter‐relationships between the different parts of the economy, the data in the table can be used to compute national income and the shares of different sectors such as agriculture, manufacturing, and services in total value added. Further, the approach used to compile the table provides a way to subject King's data to as much independent assessment as is possible given alternative sources of information. Sensitivity analysis is used to assess the impact on national income and sector shares of alternative estimates of the grain harvest, metal manufacture, and service sector output.
