Wrexham County Borough is a local government principal area centred on the town of Wrexham in north-east Wales. The county borough has a population of nearly 135,000 inhabitants. Just under half of the population live either within the town of Wrexham or its surrounding conurbation of urban villages which has a population of around 63,000 people. The remainder live to the south and east of the town in more rural areas. The area has strong links with coal-mining.
The county borough was formed on 1 April 1996. Borough status was inherited from the town of Wrexham, granted over 150 years ago. Most of the area was previously part of the district of Wrexham Maelor - with several communities coming from Glyndŵr - in the county of Clwyd.
The area includes a portion of the eastern half of the historic county of Denbighshire (although not forming part of the principal area of Denbighshire), and two exclaves of historic Flintshire - Maelor Saesneg and the parish of Marford and Hoseley.
