HALF of Caerphilly's working residents travel outside the authority to get to their jobs, according to the most recent figures published by StatsWales.

The figures from 2012 show that of 72,400 working residents in the borough, 36,200 of them worked outside the county that year. Exactly the same amount worked within the borough, the figures show.

In Blaenau Gwent, which had the second lowest number of working residents in Wales after Merthyr Tydfil, 47 per cent of the 25,700 working residents travelled outside the county to get to work, while in Torfaen that figure was 42 per cent in 2012.

In Monmouthshire 41 per cent of its 41,300 working residents left the county to get to their job in 2012, and in Newport just 32 per cent of residents left the county for work.

But those two counties relied most heavily of the Gwent authorities on people commuting into their areas, with 42 per cent of each of their total number of workers coming from outside the county in 2012.

In Torfaen the figure was 37 per cent of its 33,200 workers, in Caerphilly the figure was 36 per cent of 57,000 workers and in Blaenau Gwent the figure was 25 per cent, with 4,500 people commuting into the county to make up 18,000 people working in the authority.

The highest number of working residents who worked within their home authority in Gwent was to be found in Newport, where 68 per cent of working residents have jobs.

In Monmouthshire that figure was 59 per cent, dropping to 58 per cent in Torfaen, 53 per cent in Blaenau Gwent and 50 per cent in Caerphilly.
