All kinds of local and regional data confirm the faster muslim growth rate. The two provinces with the highest relative population growth between 1981 and 1991 are Kashmir (28%) and Lakshadweep (27%), both with a Muslim minority though in very divergent economic and political conditions; followed by Madhya Pradesh (26%) and Uttar Pradesh (25%). In Uttar Pradesh, between 1981 and 1991, the Muslim percentage rose from 15.53% to 17.33 %, in Bihar from 14.13% to 14.81%, in West Bengal from 21.51 to 23.61%. While in Bihar birth control seemed to have a slight effect in a decrease of the decadal increase from 30.03% in 1971-81 to 29.5% (still more than 5% higher than the Hindu figure) in 1981-91, there was a much larger increase in the decadal increase in U.P. from 29.11% to 36.54%, and in West Bengal from 29.55% to 36.89%.
