**5. Conclusion**

From the above discussion the highest crude birth rate was 45.9 (1984) and minimum crude birth rate was 15.1 (2007) and the maximum crude mortality rate to be 17.8 (1984) minimum crude mortality rate was 7 (2004). The decline in crude birth rate (21.8) and crude mortality rate (7.1) in the year 2011 was found. Industrialization brought a drastic change in the economic growth of the people as they started to exchange ideas and get more involved in the change and development. This demographic transition in India led to enhanced education levels for women in India (2011) and hence decreasing crude birth rate and mortality rate. For the year 2011, the percentage distribution of second and higher order live births by interval between current and previous live birth has been shown in few states of India. The spacing between children in the rural and urban areas implies that about half of the birth should have spacing 36 months and above. Most of rural and urban areas now have 70% of births which have birth interval of 24 and more months. The study shows the confidential interval for the highest crude birth rate 95% CI = 32.07–39.21 (1984) and least crude birth rate 95% CI = 20.67–25.23 (2011). Likewise, the highest crude mortality rate of 95% CI = 9.813–16.85 in 1984 and least crude mortality rate of 95% CI = 5.82–8.63 in the year 2011 can be noted. These are the key factors for the crude birth and crude mortality rate to decline from 1981 to 2011. The confidence interval and lower SE helps to get the accurate mean of the population in a particular region with a range.
