Housing, location, poverty, and hurricanes all contributed to the massive loss of life in the 2010 Haiti earthquake:
1) Most of the 3 million people in Port-au-Prince lived in slums with poorly constructed housing built on steep slopes without foundations or building codes.
2) The earthquake struck near the capital at a shallow depth, causing widespread damage.
3) Two-thirds of Haitians lived on less than $1 per day, and many resided in extreme poverty without access to basic necessities.
4) Previous hurricanes had destroyed farms, caused food shortages, and increased urban migration, straining housing availability.
