special code was provided for Par- sis (these cards pertained to the 20 per cent sample of Greater Bombay Population of about 8 million). The number of cards obtained (12,740) formed 19.7 per cent of the total number of Parsis in Greater Bombay, The sex-ratio of the sample population, however, was 994 as against 954 for the entire Parsi population in Greater Bombay. It thus appears that males are somewhat over represented in our sample compared to their proportion in the total population.
