Productivity measures are constructed from output and input data. This chapter focuses on output measures produced within the UK National Accounts. The basic framework of the UK National Accounts is provided alongside an explanation of how they are constructed.
A detailed description of gross domestic product (GDP) is given and compared with gross value added (GVA). As part of this, the three approaches to measuring GDP (income, output and expenditure) are explained and compared, as are the processes used to generate measures of output.
This chapter also outlines the Input-Output Supply and Use Tables as they are produced in the UK and how they are used as a framework to reconcile the three different approaches to measuring GDP. The industry analyses produced through the supply and use framework, provide the key output data to work on productivity for a range of users.
