Notes: This paper describes the composition of the public sector in the United Kingdom and traces the development and contribution to the economy of the three main sub-sectors-central government, local government and public corporations—over the past thirty years. Relevant data for output, employment, fixed capital formation and national wealth set the public sector into perspective with the economy as a whole and illustrate how its share of human and other resources has changed over the years. While all four measures show the public sector share of the total to have been around 30 percent in 1980, historically the changes have moved very differently. The slow, but fairly steady, increase in the share of employment and output contrasts with very marked changes in the other two measures. Although public sector fixed investment nearly doubled in real terms between 1950 and 1980 its share of total investment declined from 48 to 31 percent, a much smaller share being taken by dwellings, electricity supply and the railways. In terms of the share of national wealth the public sector moved from a state of indebtedness to the rest of the economy in the fifties and sixties to a position of holding nearly one third of the value of tangible and financial assets in the late seventies.A small part of the paper considers the international dimension, but because few other countries use the concept of a public sector, this section examines only the relationship between total tax revenue and GDP in a number of countries and employment in general government.The problems of determining the boundary of the public and private sectors occurs most frequently at the interface between public corporations and private enterprises; the rules for deciding classification are set out in so far as they can be specified.The last sections of the paper put the statistics into their policy context and consider the value of public sector aggregates. The conclusion is that a general case cannot be made to justify assembling public sector aggregates for all countries; the need will be determined by the economic policies being pursued in a particular country. Although the United Kingdom gives considerable prominence to a public sector financial aggregate, the Public Sector Borrowing Requirement, the functions of the public corporations and the rest of the public sector are so disparate that consolidated accounts for the public sector are no longer prepared.
