India’s Historical Demographic Transition: An Analysis of Population Trends with a Special Focus on Bihar

India's demographic trajectory has experienced a significant paradigm shift, marked by dropping mortality rates, falling fertility rates, and enhanced urbanization. Bihar, the country's most populous and densely populated state, embodies the intricacies of this demographic transformation. The state's rapid population growth, pervasive poverty, and human development shortcomings present a unique set of challenges that warrant closer examination. India agonizes from numerous economic and social issues like healthcare, unemployment, poverty, Illiteracy, etc. The gap in birth rates between rural and urban areas have lessened over time, yet rural regions continue to show higher birth rates trend. In all over the country, the birth rate has decreased by 11% over the past decade, dipping from 21.8 to 19.5. Explicitly, rural areas have seen a 9% decline (from 23.3 to 21.1), while urban areas have experienced alike 9% decrease (from 17.6 to 16.1). In the last five decades, India's death rate has dropped, falling from 14.9 in 1971 to 6.0 in 2020. The Infant Mortality Rate have been reduced indicating upgradation in the nation's health. But one in 36 infants still capitulates to mortality within their first year. Indian culture supports the prevalence of larger family sizes, leading to high population in the country. Advancements in medical facilities in the nation over the time have led to a decline in infant and overall mortality rates, leading to an addition in the current population size. Family planning depends on literacy and awareness (especially among females). In Bihar, socio-economic culture reflects more children as a future security. Although, India is experiencing a demographic transition, Bihar is still in the early stage of the demographic transition. National population control policies have had a diverse influence crossways different regions of India.
