This study is an effort to depict the scenario of age patterns of fertility in major states and districts in India with the view that a better understanding of the fertility transition taking place at national level might be possible by a detailed study of the fertility transition taking place at sub-national or below state level. This study begins with the discussions on levels and trends of fertility at national and state level through the combination of statistical tools viz. Deciles & Quartiles and analytical tools viz. parameters of Quadratic Spline model. Due to paucity of data at sub-national or below state level, model fertility tables are derived to obtain the age specific fertility rates for districts in India and discussed comprehensively using aforementioned statistical and analytical tools.
