The London Borough of Merton is a borough in south-west London, England. The borough was formed under the London Government Act 1963 in 1965 by the merger of the Municipal Borough of Mitcham, the Municipal Borough of Wimbledon and also the Merton and Morden Urban District, all formerly inside Surrey. The borough derives its name from the historic parish of Merton, which was centred around the location now referred to as South Wimbledon. The local authority is Merton London Borough Council.
Based on population estimates made in the middle of 2014, the borough includes a permanent population of about 203515 inhabitants. Merton is served by a wide selection of National Rail stations across the borough, along with the southern tip of the London Underground's Northern line along with the District line around the Wimbledon branch. It's the only London Borough which has tube, rail and tram services.
The primary industrial centres in Merton are Mitcham, Morden and Wimbledon, of which Wimbledon is the largest. Other smaller centres consist of Raynes Park, Colliers Wood, South Wimbledon, Wimbledon Park and Pollards Hill. Each year, Wimbledon, one of the four tennis Grand Slam tournaments, is held at the All England Lawn Tennis and Croquet Club in Church Road Wimbledon. The occasion happens over a fortnight at the end of June and start of July and it's the biggest annual sporting occasion to take place in the United Kingdom, attracting over 200000 guests throughout the Wimbledon fortnight.
