Figures released earlier by the Office for National Statistics showed that the unemployment rate was 4.2% in the three months to August, down from 4.3% in the three months to July. This was the ONS’ first month using new methodology to calculate the rate.
The data also showed that employment declined by 82,000 following a 113,000 fall in the previous quarter.
ONS director of economic statistics Darren Morgan said: "Today we have produced a new metric, produced by adjusting our headline survey estimates using robust administrative data sources that we receive from other government departments. This maintains the accuracy of our key statistics.
"This new metric shows that in the latest period the employment rate was down a little, with small rises in the rates for both unemployment and those neither working nor looking for work."
