Most Hazara live in central Afghanistan in an area known as the Hazarajat. Others live in areas north of the Hindu Kush. The Hazarajat and other Hazara territories are mountainous. The climate is severe in winter, with heavy snowfall; summers are mild but short, particularly at higher elevations. The Hazarajat, considering its harsh terrain, is densely populated. The Hazara are roughly estimated to number between 1 and 1.5 million in Afghanistan and between 17,000 and 70,000 in Pakistan. The Hazara were traditionally nomads who subsisted by herding sheep and goats; they also raised horses for fighting feuds. Mixed grain farming is now their primary subsistence activity. The Hazara are one of Afghanistan's most impoverished ethnic groups and one of the most resistant to central-government control.
