In Pakistan, the majority of Gujarati-speaking communities are in Karachi including Dawoodi Bohras, Ismaili Khojas, Memons, Kathiawaris, Katchhis, Parsis (Zoroastrians) and Hindus, said Gul Hasan Kalmati, a researcher who authored "Karachi, Sindh Jee Marvi", a book discussing the city and its indigenous communities. Although there are no official statistics available, community leaders claim that there are three million Gujarati-speakers in Karachi – roughly around 15 percent of the city’s entire population.
