Categorizing the World

After visiting around 100 countries I have found it neccessary to further categorize the World Countries into sub regions to make room for all in the menus. Instead of historical or political regions I think the most simple yet specific way is using the geographical regions as follows:

Africa
Northern Africa – covering everything above the Saharan desert from Egypt to Morocco
Eastern Africa – Sub Saharan countries in the East ranging from Sudan to Mozambique
Western Africa – Sub Saharan countries ranging from Mauritania to Congo
Southern Africa – Everything between Angola and Zimbabwe down to South Africa

Asia
North and Eastern Asia – Everything from Russia to Japan
South Eastern Asia – All countries between PNG and Philippines to Myanmar
South Central Asia – Bangladesh to Iran, reaching from Khazakstan in the North to the Maldives in the South
West AsiaTurkey and Israel to Oman and the rest of the Gulf States

South America
Northern South America – Ecuador to French Guiana
Western South America – Peru to Chile
Eastern South America – Brazil to Argentina

North America
Northern America – USA and Canada
Central America – The continental countries from Mexico to Panama City
Carribean – all island nations in North and South America

Europe
Northern Europa – Skandinavia and Great Britain
Eastern Europe – The Baltics down to Turkey
Central Europe – Germany and the landlocked countries around it
Southern Europe – Greece to Portugal

Oceania
North Pacific – Palau, Micronesia, Marshall Islands
South Pacific – The remaining small island nations ranging from Solomon Islands to the Cook Islands
South Western Oceania – Being the bigger countries Papua New Guinea, Australia and New Zealand

On a map it would look somehow like this:
