Nigeria by State


The Federal Republic of Nigeria is divided into six geopolitical zones, commonly called zones, which were created in the 1990s. They would be quite helpful to group the sites of the country, unfortunately they are used for administration but not in literature or addresses or on maps. So we decided to use the smaller divisions named States, which are official, found on maps, Google Earth and OSM. Nigeria is a federation of 36 states, each of which is semi-autonomous. As the country has very few underground sites, we list only those states which actually have sites.
