Economy

Oil refining at Milford Haven was a mainstay of the county's economy. Agriculture was also important, with sheep and hardy cattle in the mountains and valleys of the east and north-east; arable farming along the drier coastal areas; and dairy farming in the central region. Tourism and forestry were significant sectors. Anthracite and hard coal were mined on the extension of the south Wales coalfield in the south-east. Llanelli was the focus of the county's light industry.
