The document analyzes trends in female labor force participation (FLFP) in India from 1981-2011 across 15 major states. It finds that in some states, FLFP follows a U-shaped curve as predicted by the "Feminization-U" theory where rates initially decrease with economic development before rising again. Panel regression analysis indicates that rising literacy rates, declining fertility rates, increasing urbanization, and rising NSDP explain the downward portion of the U, while further increases in these variables along with economic factors explain the upward turn. The U-shape is observed for certain types of labor in states like Kerala, Maharashtra, Madhya Pradesh, and Orissa. Other states show only increasing or decreasing FLFP trends
