Last year, YouGov found that only 43 percent of Americans knew Puerto Ricans were U.S. citizens. A poll conducted after Maria by Morning Consult showed that number may be up, but only slightly: Just 54 percent of Americans knew Puerto Ricans were U.S. citizens.

Morning Consult also found a relationship between how much people knew about Puerto Rico and how much they supported post-Maria aid. Among Americans who knew Puerto Ricans were U.S. citizens, about 8 in 10 supported government aid, compared to just 4 in 10 people who did not know. Overall, 64 percent were in favor of aid to the island.
