Marking your Fourth with flags, fireworks, parades and backyard barbecues? There are some interesting, little-known Census numbers behind Independence Day.
Benjamin Franklin, 70, from Pennsylvania, was the oldest person who signed the Declaration of Independence. Edward Rutledge, 26, South Carolina, was the youngest.
John Hancock was the first to sign the Declaration. Because he was working with a blank space, his signature is the largest -- and therefore the most famous. That's also why his name is often a synonym for "signature."
Two future presidents also signed it: John Adams and Thomas Jefferson. Interestingly, both died on the 50th anniversary of the signing on July 4, 1826.
Charles Carroll, from Maryland, was the last surviving signer. He died in 1832 at 95.
In July 1776, 2.5 million people were living in the newly independent nation.
It's estimated that 318.4 million people now live in the United States.
2. Fireworks and flags
$203.6 million worth of fireworks were imported from China in 2013 -- which makes up 95 percent of the United States' fireworks.
That same year, $3.9 million dollars in American flags came from China. That's 97 percent of the flags imported to the United States.
3. Patriotic towns
Just one place (it's not quite a town) in the country has "patriot" in its name: Patriot, Ind. Patriot's estimated population is 205.
59 places contain "liberty" in the name. Eleven of them are in Pennsylvania.
136 places have "union" in the name. Pennsylvania, again, has more of them than any other state.
The country's early leaders are also among the most commonly used words in place names: Washington (127 places),Franklin (118 places), and Lincoln (95 places).
4. No love lost
Although they were our foe in 1776, the British is now our seventh-leading trading partner today.
In 2013, $100 billion was traded between the United States and the United Kingdom.
5. On your grill
Chances are, the hot dogs and sausages you'll eat on the Fourth of July come from Iowa. It's home to an estimated 19.8 million hogs and pigs.
Steaks and burgers, however, likely come from Texas. It's estimated that Texas produced 6.1 billion pounds of cattle in 2013.
