National capital Delhi has around 61,000 flesh trade workers while Karnataka and Maharashtra have third and fourth highest number of female sex workers in the country.
This has been revealed by the health and family ministry after an RTI application filed by Delhi resident Ved Pal, reported the Times of India.
"The estimate of female sex workers is based on a mapping study undertaken in 2009. About 19% of the sex workers were unregistered," stated the health ministry.
"Total number of registered sex workers is 6.96 lakh as per information from state AIDS control societies. This number is based on the line listing of targeted interventions in the states and it may change as per the new registrations," the ministry said in its reply.
