In this paper, we analyse the availability of infrastructural facilities across the Indian States and Union Territories through Infrastructure index. In Literature, the impact of infrastructure on economic growth and development is positive and highly significant. On the basis of literature, the paper tries to find out the relationship between availability of infrastructure and PCNSDP using OLS regression model in various States and Union Territories. The result indicates that there exists inter-state disparity in availability of infrastructural facilities in Indian States and Union Territories. There exists a significant positive relationship between Infrastructure Index and PCNSDP.
