India has been a secular federal republic since 1950, governed in a democratic parliamentary system. It is a pluralistic, multilingual and multi-ethnic society. India's population grew from 361 million in 1951 to 1,211 million in 2011.[49] During the same time, its nominal per capita income increased from US$64 annually to US$1,498, and its literacy rate from 16.6% to 74%. From being a comparatively destitute country in 1951,[50] India has become a fast-growing major economy, a hub for information technology services, with an expanding middle class.[51] It has a space programme which includes several planned or completed extraterrestrial missions. Indian movies, music, and spiritual teachings play an increasing role in global culture.[52] India has substantially reduced its rate of poverty, though at the cost of increasing economic inequality.[53] India is a nuclear-weapon state, which ranks high in military expenditure. It has disputes over Kashmir with its neighbours, Pakistan and China, unresolved since the mid-20th century.[54] Among the socio-economic challenges India faces are gender inequality, child malnutrition,[55] and rising levels of air pollution.[56] India's land is megadiverse, with four biodiversity hotspots.[57] Its forest cover comprises 21.4% of its area.[58] India's wildlife, which has traditionally been viewed with tolerance in India's culture,[59] is supported among these forests, and elsewhere, in protected habitats.
