The improvements in employment rate, informal sector wages, industrial density and banking density have contributed towards the enhancement of the Economy and Business Climate sub-index. With regard to the sub index of the Well-being of the People, high performance in availability of healthcare facilities, availability and quality of education, wealth of people and availability & usage of entertainment facilities were the key drivers. The reduction observed in the Socio-Economic Infrastructure sub-index was led by reduced levels of pipe borne water quality, female participation in civic activities and available transport facilities. However, the aspects of road coverage, availability of electricity, crime free environment and availability of Information and Communication Technology (ICT) facilities in schools have shown improvements within the Socio-Economic Infrastructure sub-index, it says.
