Census of India pegged average literacy rate to be 74.4% in 2011 while National Statistical Commission surveyed literacy to be 77.7% in 2017–18. Literacy rate in urban areas was higher 87.7% than rural areas with 73.5%. There is a wide gender disparity in the literacy rate in India and effective literacy rates (age 7 and above) was 84.7% for men and 70.3% for women. The low female literacy rate has a dramatically negative impact on family planning and population stabillisation efforts in India. Studies have indicated that female literacy is a strong predictor of the use of contraception among married Indian couples, even when women do not otherwise have economic independence. The census provided a positive indication that growth in female literacy rates (11.8%) was substantially faster than in male literacy rates (6.9%) in the 2001–2011 decadal period, which means the gender gap appears to be narrowing.
