Use upper case for definite geographical places, regions, areas and countries (The Hague, Transylvania, Germany), and for vague but recognised political or geographical areas: the Middle East, South Atlantic, East Asia (which is to be preferred to the Far East), the West (as in the decline of the West; adjective, Western), the Gulf, the North Atlantic, South-East Asia, the Midlands, Central America, the West Country.
Lower case for east, west, north, south except when part of a name (North Korea, South Africa, West End) or part of a thinking group: the South, the Midwest, the West (in the United States, but lower case for vaguer areas such as the American north-east, north-west, south-east, south-west), the Highlands (of Scotland), the Midlands (of England). If you are, say, comparing regions some of which would normally be upper case and some lower case, and it would look odd to leave them that way, put them all lower case: House prices in the north-east and the south are rising faster than those in the midwest and the south-west.
