Assessment of the Per Capita Investment in Key Infrastructure Development in Rivers State, Nigeria

Abstract

Public investment in core social infrastructure plays a critical role in economic development, human capital formation, and spatially inclusive growth. In developing contexts, however, infrastructure outcomes depend not only on aggregate expenditure levels but also on how equitably resources are distributed across populations and space. This study evaluates real per capita investment in education and healthcare infrastructure in Rivers State, Nigeria, within a spatial justice framework. Adopting a quantitative spatial-analytical approach, the study integrates inflation-adjusted capital expenditure data (constant 2010 ₦), population estimates, and Geographic Information System (GIS)-based analysis to examine inter-district investment patterns across the three senatorial districts from 2002 to 2024. Per capita investment levels were computed to enable population-adjusted comparison, while the coefficient of variation (CV) was applied annually to measure spatial inequality. The findings reveal pronounced temporal volatility and persistent inter-district disparities in both sectors. Educational infrastructure investment experienced episodes of extreme inequality during years of selective allocation, followed by periods of moderate but sustained imbalance despite increased funding. Healthcare investment exhibited even greater instability, characterized by cycles of sector-wide neglect, concentration in specific districts, and limited convergence. Although some years recorded relatively balanced distribution, high CV values in several periods indicate that fiscal expansion did not consistently yield equitable outcomes. Overall, infrastructure investment in Rivers State has been uneven and structurally imbalanced. Achieving spatial justice requires institutionalized population-adjusted allocation frameworks, strengthened medium-term planning, and routine GIS-based monitoring to ensure inclusive infrastructure provision.
