Hurricane Maria struck Puerto Rico on Sept. 20 and, according to the latest figures from the island government, killed at least 45 people. It also created a new surge of migration that could have lasting demographic effects on Puerto Rico and the mainland.
Tens of thousands of islanders left for the U.S. mainland to escape the immediate aftermath of the storm. With conditions back home still grim — about 85% of residents still lack electricity and 40% are without running water, and neither is expected to be fully restored for months — many find themselves scrambling to build new lives away from the island.
