The main ethnic groups in the province are the Baloch people and the Pashtuns, who constitute 52% and 36% of the population respectively (according to the preliminary 2011 census). The remaining 12% comprises smaller communities of Brahuis, Hazaras along with other settlers such as Sindhis, Punjabis, Uzbeks and Turkmens. The name "Balochistan" means "the land of the Baloch". Largely underdeveloped, its provincial economy is dominated by natural resources, especially its natural gas fields, estimated to have sufficient capacity to supply Pakistan's demands over the medium to long term. Aside from Quetta, the second-largest city of the province is Turbat in the south, while another area of major economic importance is Gwadar Port on the Arabian Sea.
