ONE in five workers across Kirklees is employed in manufacturing, a survey has revealed.
Figures from the GMB general union showed that about 38,000 people work in the district's factories and mills.
And Kirklees has the second-highest number of manufacturing jobs in Yorkshire, behind Leeds on 42,000.
The district also accounts for 1% of the UK's 3.72m manufacturing workers.
The survey showed there were 37,000 manufacturing jobs in Bradford and 34,000 in Sheffield.
Calderdale was third from bottom in the regional poll, with just 15,000 people working in manufacturing.
The survey showed that manufacturing provides work for 367,000 people in Yorkshire.
That represents 15.7% of all employment in the region and 9.8% of the UK's manufacturing jobs.
However, the survey also highlighted how Yorkshire had fallen behind other regions in providing manufacturing posts.
It said there were 693,000 workers employed in manufacturing in the South-East. This is 18.6% of the total and makes it Britain's biggest manufacturing region.
The West Midlands was next with 469,000, followed by the North-West on 419,000.
Gerry Nelson, GMB Yorkshire regional secretary, said the survey reflected the fall in jobs in Britain's former manufacturing heartlands.
He added that the survey showed manufacturing was still undervalued by the nation.
