District-level life expectancy at birth \(({e_0})\) in India, person NFHS-4 (2015–16). Figure 1 shows the variation in life expectancy at birth \(({e_0})\) across 640 districts for the total population from NFHS-4 (2015-16) in India. The range of district-level \({e_0}\) is from 53.7 years to 93.6 years. The lowest observed \({e_0}\) is in Rewa district (53.7 years) and the highest is in Upper Siang district (93.6 years). Fifteen districts have \({e_0}\) below 60 years. The distribution of \({e_0}\) is divided into seven categories. Deep green and deep red shows the higher and lower distribution of \({e_0}\) respectively. Deep green shaded districts have \({e_0}\) of 85 and more years, located in southern state Kerala, Tamil nadu and northeastern states Arunachal Pradesh, Manipur and some other districts. Deep red shaded districts have \({e_0}\) below 60 years, located in central region states Uttar Pradesh, Madhya Pradesh, Chhattisgarh and eastern region state Odisha. In conclusion, there are significant differences in life expectancy at birth \(({e_0})\) at the district level in India based on NFHS-4 (2015-16) data.
