The world’s entire population could fit inside the state of Texas

Get this: If all of us lived at the same density level as New York City, the world’s population would cover about 250,404 square miles. That means there would technically be enough space for all 7.5 billion people to live in Texas, which is 268,597 square miles in total. Granted, things might get a little crowded.

Over 40 buildings in New York City have their own zip codes

Speaking of densely populated areas, Manhattan—the most crowded of New York City’s five boroughs—is so cramped that it has over 200 zip codes. Some skyscrapers are even large enough to have one of their very own. The Empire State, Chrysler, and MetLife buildings are just a few that can claim exclusive rights to their own unique zip code. Don’t miss these 30 geography facts everybody keeps getting wrong.

Alaska is the country’s westernmost AND easternmost state

When you look at a map, you’ll notice that Alaska is the westernmost part of the United States. But you might not guess that Alaska is also the country’s easternmost state, too. How could that be? Islands in Alaska’s Aleutian chain extend out into the Eastern Hemisphere.

Boston and Austin are the only two U.S. state capitals with rhyming names

Raleigh and Albany? Not so much. Concord and Carson? Try again. Turns out, Boston and Austin are the only two state capital cities in the United States with names that rhyme. We bet you didn’t know these other surprising facts about America, either.

From Stamford, Connecticut, all cardinal directions lead to New York

If you drove north in a straight line from Stamford, Connecticut, you would end up in the state of New York. Same goes for traveling south, west, and east (though you’d need an amphibious vehicle to complete the eastern journey). Try it for yourself!

Parts of Nevada are farther west than Los Angeles, California

California is one of the westernmost U.S. states and makes up the majority of the nation’s west coast. Meanwhile, the city of Reno, Nevada, is nearly 300 miles from the ocean. But believe it or not, Reno is roughly 86 miles farther west than the coastal city of Los Angeles.

Neither Florida nor California have the longest U.S. coastline

Most people would probably guess that Florida or California have the longest coastlines in the country. But in reality, Alaska is the national coastline champ. Its coast spans 6,640 miles or 10,686 km in total—which is more than all of the other 49 states combined. Think you can pass Geography 101? Take this geography quiz to find out.

The United States boasts a mountain that is taller than Mount Everest

At 29,028 feet (or 8,848 meters), Mount Everest is considered the world’s highest mountain above sea level. However, the tallest mountain in the world is actually located in the United States. Hawaii’s Mauna Kea is over 32,000 feet (10,000 meters) tall when measured from the seafloor. Because it only reaches 13,796 feet (4,205 meters) above sea level—and over half of its base sits beneath sea level—it often doesn’t receive the same hype as the Himalayas. Don’t miss these 51 facts you’ve always believed are actually false.

California has more residents than all of Canada

Canadian residents celebrated a milestone in 2015 when the country reached a population of 36 million for the first time. But that’s still about three million people short of California’s population. Roughly 39 million people live in the Golden State, which also happens to be the most populous state in America.

You can walk from the United States to Russia

Yes, really! During certain times of the year, you can travel by foot between the United States and Russia, thanks to two islands named Big and Little Diomede. Big Diomede is the easternmost part of the Russian Federation; its neighbor, Little Diomede, is a part of Alaskan territory. When the water freezes in the winter, brave travelers can cross the short distance—about 2.4 miles—between the two islands. Do so at your own risk, though; while experts say making the journey is theoretically possible, it is dangerous and not recommended.

The United States is home to the world’s shortest river

Go ahead and name a few American rivers. The Mississippi, the Colorado, and the Rio Grande might be the first to come to mind. While these famous waterways get a lot of fanfare, many forget about little Roe River in Montana. Roe only flows for about 200 feet, making it the shortest river in the world. Learn more United States trivia your teacher never taught you.

Two U.S. states do not share borders with any other U.S. state

They are (you guessed it!) Hawaii and Alaska. On the flip side, two other states share borders with eight states each, the most in the entire country. Missouri borders Iowa, Illinois, Kentucky, Tennessee, Arkansas, Oklahoma, Kansas, and Nebraska. Meanwhile, Tennessee borders Kentucky, Virginia, North Carolina, Georgia, Alabama, Mississippi, Arkansas, and Missouri.

The western United States used to have enormous lakes

During a period called the “Last Glacial Maximum” over 20,000 years ago, the states of Nevada, Utah, Oregon, and California contained bodies of water so huge they rivaled the Great Lakes. Over time, the giant lakes shrank as global temperatures began to rise until they eventually disappeared altogether. Here are 50 more astonishing facts you never knew about all 50 states.

africashutterstock (2)

A piece of Africa is underneath the United States

You might recall that long ago, a supercontinent called Pangaea broke apart to form the seven continents as we know them today. Now, 250 million years later, geologists have discovered a chunk of Africa that stuck around in North America. It’s located near Alabama, just off the coast of the southeastern states.

The United States borders three oceans—not just two

It is common knowledge that the United States shares a coastline with the Atlantic and the Pacific Oceans. What few realize, though, is the country also touches the Arctic Ocean along Alaska’s northern border. See if you can solve these 15 stumpers from the National Geographic Bee.

The four largest U.S. cities are in Alaska

When you think of big cities, you probably think of bustling metropolises like New York, Chicago, and L.A. While those cities might be some of the most highly populated, they aren’t the biggest in terms of area. All of the four most sprawling cities are in Alaska: Sitka, Juneau, Wrangell, and Anchorage.

Only one U.S. state grows coffee

Sorry, local foodies, but most of your beans will have to come from overseas. The only place you’ll find coffee beans growing in the United States (barring Puerto Rico) is Hawaii. And even more surprisingly, the pineapples that made Hawaii famous were originally imported there from South America, and Florida used to be the primary U.S. pineapple state.

capital originalShutterstock (2)

America’s first capital wasn’t Washington, D.C.

And nope, it wasn’t Philadelphia either. When the U.S. Constitution was ratified, the country’s capital was New York City, where it stayed for a year before moving to Philly, then D.C.

los angeles nameShutterstock (2)

Los Angeles used to have a much longer name

Historians dispute what the first settlers called the city, but they can at least agree it was longer than “L.A.” According to the County of Los Angeles, it was first known as El Pueblo de la Reyna de Los Angeles but eventually shortened because, well, that was quite the mouthful. You won’t want to miss how every U.S. state got its name.

triply landlockedShutterstock (2)

Only one state is “triply landlocked”

A landlocked state doesn’t touch an ocean, gulf, or bay; a doubly landlocked state means you’d need to travel through two other states (or a state and a Canadian province) to get to one of those bodies of water. The only state that’s triply landlocked—is three states/provinces away from the ocean on every side—is Nebraska.

most earthquakesShutterstock (2)

The state with the most earthquakes isn’t California

The Golden State might be known for its crazy-frequent earthquakes, but it’s actually not the top state for shakes. Alaska has more earthquakes every year than any other state, thanks to the fact that it sits on one of the world’s fastest-moving underwater tectonic faults. Don’t miss these other 46 weird facts that most people don’t know.

capital without mcdonaldsShutterstock (2)

There’s only one U.S. capital without a McDonald’s

You can’t make a trip to Montpelier, Vermont, and expect to get a Big Mac without traveling to another town. It also happens to be the smallest U.S. capital, which could explain its lack of Golden Arches.

US bordersShutterstock (2)

The U.S. border is next to more than two countries

Of course, the continental United States is south of Canada and north of Mexico, but that’s not all. If you include ocean borders, America is also neighbors with Russia, Cuba, and the Bahamas. Now that you’re several facts smarter, check out these 100 incredible facts about practically everything.
