Our chart this week is on the change in quarterly GDP over the past five years, analysing the change between GDP as calculated by the Office for National Statistics (ONS) of £549bn in the first quarter of 2019 and £688bn in the first quarter of 2024, a net increase of £139bn.

Inflation, at 4% a year on average over the past five years, was the largest contributor to the change, being £120bn out of £139bn of the increase. An increase in population of more than 0.6% a year added a further £22bn, but this was offset by £3bn from negative economic growth per capita of 0.1% on average over the past five years.

Breaking down the £19bn change resulting from economic growth (0.5% a year on average), between population change and economic growth per capita in this way highlights how net inward migration has been one of the most significant drivers of the UK economy over the past five years. 

While there are multiple reasons why the electorate decided to vote in a new government in the recent UK general election, the £41 reduction in quarterly GDP per capita over the past five years after adjusting for inflation – and the associated drop in living standards – to £9,994 per person in 2024 Q1 is likely to have been one of them.

The good news is that the next five years may be better, with monthly GDP up by 0.40% over the course of April and May 2024. This can be broken down between an estimated population growth of 0.16% and an increase in monthly GDP per capita over the two months of 0.24%, a positive sign, especially in the light of the latest ICAEW Business Confidence Monitor reporting that business confidence has risen to its highest level in over two years.
