Only 58% of residents know that the United States declared its independence in 1776. 26% are unsure, and 16% mentioned another date.

There are age differences on this question. Younger Americans are the least likely to know the correct answer. Only 31% of adults younger than 30 say that 1776 is the year in which the United States broke away from Great Britain. 59% of residents between 30 and 44 report the same. Americans 45 to 59 — 75% — are the age group most likely to have the correct answer. Among those 60 and older, 60% report that 1776 is the year in which the United States declared its independence.

When it comes to gender, men — 65% — are more likely to respond with 1776 than are women — 52%.

And, for the second year, about one in four Americans doesn’t know from which country the United States declared its independence. While 76% correctly cite Great Britain, 19% are unsure, and 5% mention another country.

A comparable proportion of Americans were similarly informed at this time last year. At that time, 74% thought the United States declared its independence from Great Britain, 20% were unsure, and 6% mentioned another country.

80% of those 60 and older, 77% of those 45 to 59, and 77% of those between 30 and 44 report the nation’s founding fathers revolted against Great Britain. This compares with 67% of those under the age of 30 who say the same.
