Just 345 people in Montgomeryshire were claiming Job Seekers Allowance in September, according to figures released by the Office for National Statistics.
The figure represents 1.1 per cent of the economically active in north Powys, including Newtown.
There were also only 90 claimants aged 18-24 within the constituency, 30 lower than in September 2016.
Glyn Davies, MP for Montgomeryshire, said the figures were “astonishingly low”.
The number of claimants is down from 370 in August 2017, and is 70 lower than in September 2016.
There were also only 90 claimants aged 18-24 within the constituency, 30 lower than in September 2017.
Commenting on today’s figures, Glyn Davies MP said: “The latest unemployment statistics for Montgomeryshire are astonishingly low, and continues the hugely impressive trend which has seen employment rates within the constituency at a far higher than when I first became the MP in 2010.
“Today, Montgomeryshire is in within the top 100 constituencies out of 650 within the UK for the lowest unemployment levels. It is also pleasing that the number of claimants aged between 18-24 continues to fall, having decreased by a third from the previous month.”
He added: “Whilst there is still much to do, today’s statistics tell us that Montgomeryshire is well placed to continue to develop its employment base, and reinforces the upward trend of businesses and employers expanding within the constituency.
