ICMDA's West Africa region covers the nine countries that do not have French as a major language (see Francophone Africa for other West African countries).

There are five fellowships affiliated with ICMDA, Nigeria, Ghana, Gambia and the newest two movements in Liberia and Guinea Bissau..

250 million people live in the region, with over 200 million of them living in Nigeria alone - the most populous country in all Africa and seventh in the whole world.

There are 52 medical schools in West Africa - 80% of them are in Nigeria. The smaller islands and the oil-rich Equatorial Guinea do not have a national medical school.
