1,000 males (Census 2011) Fertility rate Chhattisgarh has a fairly high fertility rate (2.4) as of 2017 compared to All India (2.2) and the replacement rate (2.1). It has a rural fertility rate of 2.6 and urban fertility rate of 1.9 SC and ST population With the exception of the hilly states of the north-east, Chhattisgarh has one of highest shares of Scheduled Tribe (ST) populations within a state, accounting for about 10 percent of the STs in India. Scheduled Tribes make up 30.62% of the population. The tribals are an important part of the state population and mainly inhabit the dense forests of Bastar and other districts of south Chhattisgarh. The percentage increase in the population of the scheduled list of tribals during the 2001–2011 decade had been at the rate of 18.23%. The Scheduled Caste (SC) population of Chhattisgarh is 2,418,722 as per 2001 census constituting 11.6 percent of the total population (20,833,803). The proportion of Scheduled Castes has increased from 11.6 percent in 2001 to 12.8% in 2011. Poverty The incidence of poverty in Chhattisgarh is very high. The estimated poverty ratio in 2004–05 based on uniform reference period consumption was around 50 per cent, which is approximately double the all India level. The incidence of poverty in the rural and urban areas is almost the same. More than half of the rural STs and urban SCs are poor. In general, the proportion of poor SC and ST households in the state is higher than the state average and their community's respective national averages (except for rural SC households). Given that more than 50 percent of the state's population is ST and SC, the high incidence of income poverty among them is a matter of serious concern in the state. This indicates that the good economic performance in recent years has not percolated to this socially deprived group, which is reflected in their poor performance in human development indicators. Access to drinking water In terms of access to improved drinking water sources, at the aggregate level, Chhattisgarh fared better than the national average and the SCs of the state performed better than the corresponding national average. Scheduled Tribes are marginally below the state average, but still better than the STs at the all India level. The proportion of households with access to improved sources of drinking water in 2008–09 was 91%. This proportion was over 90% even
