Percentage of the female population between age 25 and age 64 who can, with understanding, read and write a short, simple statement on their everyday life. Generally, ‘literacy’ also encompasses ‘numeracy’, the ability to make simple arithmetic calculations. This indicator is calculated by dividing the number of female literates aged 25-64 years by the corresponding age group population and multiplying the result by 100.
