Rainham belongs of the Medway Towns conurbation its population typically consisted of under Gillingham in the unitary authority of Medway, in South East England, and part of the ritualistic county of Kent. Historically, Rainham was a separate town until, in 1928, it was contributed to the Municipal Borough of Gillingham, which was initially developed in 1903 as well as was grouped right into the latter's built-up area in analysis of the 2011 census by the Office for National Statistics. It entered into the Medway authority when Gillingham was included with the other towns to create Medway Unitary Authority in 1998. It has its very own recreation and also retail hub as well as unlike Gillingham has a conventional location generally to the south as well as which given that the late 20th century is largely property real estate. Rainham was initially a direct negotiation along the highway. The population in 1801 was 422; 2 centuries later it is well over 6 thousand. Part of the reason for this big development can be attributed to the railway. When the train came in 1858 it brought an almost prompt rise in the size of the town; when the Chatham Main Line was electrified in 1959, similar to all the locations served by it, community development began again. Among the outcomes was the building of Parkwood estate.
