More than 2 million residents in Gaza are living in a territory where more than 5,000 people live per square kilometer, according to the Norweign Refugee Council.
As many as 70% of the population in Gaza are refugees and 84% of those living there are in need of humanitarian aid. The vast majority, 98%, of groundwater is undrinkable, and more than 40% of people don't have enough to eat already.
The blockade has meant Israel controls imports and exports to the area and with limited medical supplies, Gazans have to apply for permission to travel outside of the territory for medical care. 45% are denied.
