The People's Democratic Party (PDP) is one of the two major political parties in the Nigerian political landscape. Nominally considered a center-right party, the party's main support stems from the southern states. This map reflects this north-south divide between supporters of the PDP and supporters of other parties holding seats in the state legislatures.

Because Nigeria does not use proportional representation at the federal or state level, the share of seats in a state legislature does not match the electorate's strength as a whole. This is effectively how some states have every single seat occupied by a PDP parliamentarian while some have exactly zero.

Data was collected from the corresponding Wikipedia article on Nigerian state assemblies. Because of the 2023 elections in Nigeria that elected most of the assemblies, the data used here is likely highly outdated.
