The United States is a geographically vast, consumer-driven country with a mixed economy that allows for highly diverse industries, manufacturing, skill sets, tourism, cuisine, and commerce—and a wide-reaching culture, to boot.

This country holds many things, from trees and national parks to suburban sprawl and crime. This is the land of plenty (128.45 million households in 2020), and of the few (just 321 drive-in movie theaters nationwide). In its short legacy, the country has also accrued a number of failed experiments and abandoned endeavors, including more than 3,800 ghost towns, in excess of 300 demolished or abandoned amusement parks, and a whopping 450,000 brownfield sites that are home to hazardous substances, pollutants, or contaminants. The U.S. accounts for a little over 4 percent of the global population yet contains 20 percent of the world's prisoners and is responsible for more than 30 percent of the planet's waste. But what other numbers make up this country?

To find out, Stacker scoured statistics, tourism boards, national parks service websites, and various datasets to bring examples of just how many of 50 different things exist in the U.S. From guns and movie theaters to parks and Starbucks, nothing was off limits. The research spans all 3.797 million square miles of the U.S. and looks at topics including industry, business, personal finance, entertainment, and more.

Can you take a guess as to how many public schools are in the U.S.? Do you have any clue as to how many billionaires might be residing there? Read on to find out—and learn a thing or two about each of these selection's cultural significance and legacy along the way.

Churches: 380,000 congregations

While there isn't an organization that tracks up-to-date figures on the number of U.S. congregations, the National Congregational Study Survey estimates that there were 380,000 churches in the U.S. in 2019.

Crime scene

Serial killers: 2,000

There are thousands of unsolved mysteries throughout America every year, many of which are homicides. Although it's impossible to arrive at an exact number of serial killers, officials at the Murder Accountability Project (MAP) estimate there are as many as 2,000 at large. "There are more than 220,000 unsolved murders since 1980, so when you put that in perspective, how shocking is it that there are at least 2,000 unrecognized series of homicides?" MAP's Thomas Hargrove asked Live Science. A serial killer is defined as anyone who has murdered two or more people.


Households: 128.45 million

In 2020, the United States comprised approximately 128.45 million households, defined as a group of people living in a single housing unit.

The casino industry has been hard-hit during the COVID-19 pandemic, and high numbers of coronavirus cases in Nevada are tied to the state's casinos reopening.

Subway restaurants: 23,801

With 23,801 locations in the United States in 2019, Subway is the largest restaurant chain in America. The number dwarfs McDonald's, which was 13,837 in 2019. However, the number doesn't necessarily mean the sandwich chain is experiencing total success—the number of Subway stores has decreased in the last few years, and in 2020 Subway slipped out of the top five most profitable restaurant chains in the U.S. Those more-profitable chains are Burger King, Taco Bell, Chick-fil-A, Starbucks, and McDonald's.


Bars and nightclubs: 58,074 establishments

Then COVID-19 struck, shuttering most of the industry and making for a dismal year for bars and nightclubs.

The average number of full-time sworn officers per 1,000 residents decreased by 11 percent between 1997 and 2016, dropping from 2.42 to 2.17.

Bison: 500,000

Although they once roamed in giant herds numbering up to 30 million, today there are only about 500,000 bison in America. It's still a number that impresses many citizens, though, given that they only reside in national parks and refuges in Wyoming, Montana, Oklahoma, Nebraska, Iowa, and Colorado. The animals, which are the largest land animal in North America, are called bison in the Americas and Europe and buffalo in Africa and Asia.


Veterans: 17.4 million

The U.S. contains stunning coastlines, many of which are decorated with old, historical lighthouses. There are approximately 700 lighthouses decorating the United States, the first of which was the Boston Light, built on Little Brewster Island in 1716. It was reconstructed in 1784 after being destroyed by the British. The oldest lighthouse in existence that's never been rebuilt is the Sandy Hook Lighthouse, which was constructed in 1764 and still stands.

When a commercial site gets contaminated by some sort of chemical, pollutant, or other hazardous substance, the Environmental Protection Agency labels it a "brownfield" (nicknamed after the agency's Brownfields Program, which helps clean up or mitigate the situation).

Jobs: 6.5 million openings

The number of American job openings was at 6.5 million in November 2020. The unemployment rate was at 6.7 percent in December 2020, or 10.7 million. The so-called "skills gap" helps explain how so many jobs go unfilled despite high unemployment rates due to the COVID-19 pandemic. After an initial employment downturn in early 2020, jobs started getting added back to the economy in May 2020. December marked the first month that job losses have returned. Notably, the jobs lost were women's roles, with women losing 156,000 jobs and men gaining 16,000 jobs.

Bald eagle

Bald eagles: 9,789 nesting pairs

As the national emblem of the country, the bald eagle was chosen to represent the U.S. due to its "association with authority and statehood." President John F. Kennedy later said that the "fierce beauty and proud independence of this great bird aptly symbolizes the strength and freedom of America."

Over the years, however, the real-life bird—which once numbered over 100,000—struggled to survive. It was placed on the Endangered Species List in 1967 and another updated version in 1973 but was removed in 2007 after officials said it was no longer needed. Recent counts suggest there are now at least 9,789 nesting pairs of bald eagles in the lower 48 states.
