Four years into its civil war, Syria is a “catastrophic” disaster where society has begun to disintegrate, life expectancy has plummeted, most people are jobless, and millions of children have abandoned school, a new report shows.

The Syrian Center for Policy Research, which is supported by two United Nations agencies, concludes that human development is “rapidly regressing,” which is destabilizing a country that has long been the strategic center of the Middle East.

The numbers are staggering in every category, but the shortened life expectancy stands out. In 2010, life expectancy in Syria was almost 80 years. Today, life expectancy from birth is estimated at 55 years, the report says.
