The Aga Khan Development Network deals mainly with issues of health care, housing, education and rural economic development. It says it works in over 30 countries and has an annual budget of about $1 billion for nonprofit development activities. Ismailis lived for many generations in Iran, Syria and South Asia before also settling in east Africa, Central Asia and the Middle East, as well as Europe, North America and Australia more recently. They consider it a duty to donate up to 12.5% of their income to the Aga Khan as steward.
