This paper examined the spatial inequality of development among thirty Local Government Areas of Osun
State, Southwestern Nigeria. Based on the results of Principal Component Analysis and Logistic
Regression applied to 45 indices of development in all the LGAs for year 2001, the paper identified four
major components and six predictor variables as determinants of development inequalities among the
LGAs in the State. It revealed regional inequalities of development in the state. Many development
indicators are concentrated in a few Local Government Areas that are urban based. Majority of the LGAs
are lagging behind on the components of development. This portends serious implications for development
planning in the state. It can be concluded that the economy of the entire state is largely underdeveloped.
