Many of those polled failed to correctly answer basic questions about American independence and the Constitution

Nearly half of Americans don’t know what they’re celebrating on the Fourth of July, according to a shocking poll.

July 4 marks the 250th anniversary of the adoption of the Declaration of Independence in 1776, but 46% of Americans and 61% of Gen Zers couldn’t tell you that, the Cato Institute’s national survey found.

Celebrations are taking place across the country this holiday weekend, but many Americans failed to correctly answer basic questions about the history of U.S. independence and the Constitution in the poll of 2,253 Americans aged 18 and older.
