GDP

Gross domestic product (GDP) growth is the main indicator of economic performance.

There are three approaches used to measure GDP; the output approach, the expenditure approach and the income approach.

GDP per head is calculated by dividing GDP in chained volume measures by the population estimates and projections. It is not a measure of productivity or well-being, but is a useful statistic as it removes the impact of the changing size of the population from headline GDP figures.
