SITTING in her mud-walled, tin-roofed, one-room hut, Saleha Begum coyly explains why she decided not to have any more children after the birth of her second child, a son, 13 years ago: "A bigger family would have added to our miseries." Saleha is only one of the 1,100 women of child-bearing age in Pirojali, a remote village of orchards and paddy fields, who have adopted some form of birth control. A feat which has made Pirojali (population: 19,000) a leader in the family planning movement. Its contraceptive prevalence rate (CPR) is now nearly 60 per cent, way above the national average of 45 per cent.
