In May 2023, when the British Office of National Statistics (ONS) released the March-quarter national accounts data (first estimate), which showed that real GDP grew by only 0.1 per cent in the first quarter and a rate equal to the December-quarter 2022, the critics were out in force. Brexit this. Brexit that. Graphs were created showing that Britain was recording the worst growth across the G7 nations. Brexit this. Brexit that. The Labour Party was cock-a-hoop as they continued the purge of the progressive elements in the Party. Then the second estimate came out on June 30, 2023 using additional data which the ONS said provides ‘a more precise indication of economic growth than the first estimate’, we learned that GDP “increased by an unrevised 0.1% in Quarter 1”. Brexit this. Brexit that. William Keegan who is like a cracked record stuck in a rut, wrote more UK Guardian articles bemoaning the democratic choice to leave the European Union. The problem is that all this data-centric inference was based on an illusion, which is why one must always be circumspect when dealing with this sort of data. The latest national accounts data released by the ONS on Friday (September 29, 2023) revised the first quarter result – scaling it up by a factor of three – to 0.3 per cent, which is still slow but hardly the disaster the pundits claimed.
