Population Growth and Sex Ratio in South Bihar Plain (India): A District Level Comparative Analysis

Population growth of any region is a crucial factor in the development of any region, because it helps in the management and development of the region. Apart from this sex ratio are among the most basic demographic characteristics and helps in understanding the survival of male and female. The sex ratio is said to be favorable to women, when the number of females exceeds the males, and is said to be adverse, when the number of males exceeds the females. Sex ratio in India normally remained adverse to woman but in Bihar it remained favorable to women till 1961, except the year 1931. It is because of his fact that the growth of population in the study area, occurred at faster pace, as higher female population can have a substantially higher birth rate, which will lead to higher growth of population in the study area, occurred at faster pace, as higher female population can have a substantially higher birth rate, which will lead to higher growth of population. Sex ratio can change not only the size of population but also their characteristics. Therefore, it is necessary to keep balance between male and female population, for the perpetual existence of the human population. In a state like Bihar and especially South Bihar plane sex ratio is a key factor in understanding the development of the society, because it has got both the demographic and social implications. The decrease in number of women will reduce the marriage rate which will be resulted into decrease in crude birth rate and will also lead to many social evils. In this research paper we will examine the spatio-temporal variation in growth of population and sex ratio at district level in South Bihar plain, furthermore there with a comparative analysis between population growth rate and sex ratio by means of Karl Pearson’s method of correlation.
