Production movements are analysed statistically according to the contribution of changes in, productivity within industries and activities, employment, and the re-distribution of employment between industries and activities, both singly and in combination. When applied in turn to the Index of Gross Domestic Product and the index of Manufacturing Production for the period 1948-55, the main contributors to increased output are seen to be improved productivity and higher employment levels. The Index of Gross Domestic Product increased by 27% during the period, the main contributors accounting for 67% and 22% of the value respectively. In the case of Manufacturing industry they accounted for 57% and 32% respectively, of the 42% increase in output. Significantly, a11 of the increase in employment went into manufacturing industries. The movements for the individual broad groups of industries and activities contributing to the indices were very varied so that a relatively small section of the economy accounted for a large proportion of the overall increase in production and productivity.
