How many in America?

Hedges & Company estimates there are 289.5 million registered cars in 2021, and projects 290.8 million in 2022. The year 2016 marked the first time more than 70 million cars were manufactured globally in a year (72,105,435, to be exact). Electric cars remain a small portion of all cars driven but are making inroads. In 2020, there were almost 1.8 million registered EVs in the U.S., a three-fold increase from 2016.

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. The number has been vacillating up and down over the years, increasing and decreasing rather than showing any overarching trend one way or another.

There are 63 national parks in the United States, some of the most famous of which include the Great Smoky Mountains, Grand Canyon, Zion, Yosemite, Yellowstone, and Joshua Tree. In 2020, three parks—Golden Gate National Recreation Area, Blue Ridge Parkway, and Great Smoky Mountains National Park—each enjoyed in excess of 10 million recreation visits. California and Alaska are the states with the most parks—nine and eight, respectively.  

According to the Small Arms Survey report, which analyzes gun data from 230 countries worldwide, there are more than 393 million civilian-owned firearms in America. Analysis by The Washington Post concluded that the number represents a cache large enough for "every man, woman and child to own one and still have 67 million guns left over." At roughly 120.5 guns per every 100 residents, the United States has double the ratio of Yemen, the next-highest country on the list, where there are an estimated 52.8 guns for every 100 residents.

Although the Department of Agriculture licenses some 2,400 "animal exhibitors," a much smaller number are considered true zoos and are accredited as such. The Association of Zoos and Aquariums reported 218 accredited facilities in the U.S. as of April 2021. The figure includes zoos, aquariums, nature centers, aviaries, butterfly houses, safaris, and theme parks.

There are 41,692 zip codes spread across America, each of which routes mail to its appropriate destination. The numbers range from 00501 (the lowest one for the Internal Revenue Service in Holtsville, New York) to 99950 (the highest one in Ketchikan, Alaska). Perhaps the easiest zip code to remember, according to USPS, is 12345, which belongs to General Electric in Schenectady, New York.

As of 2020, there were 13,673 McDonald's restaurants in the United States. West Virginia carries the distinction of having the highest density per population of the fast-food chain, with 5.8 stores per 100,000 residents. After that, the next most McDonald's-populated states include Arkansas, Kentucky, Michigan, and Ohio. On the opposite end, Rhode Island, New Jersey, New York, and California have the fewest McDonald's per capita.

If you tally up all of the elementary, secondary, and combined schools throughout the United States, there were a total of 98,469 public schools in operation during the 2017-18 school year, according to the National Center for Education Statistics. The number gradually increased between the '80s and late '00s, going from 85,982 schools in the 1980–81 school year to 98,916 in 2007–08. The total peaked that year and has gradually declined since.

Despite all of the lawyer jokes, Americans actually love lawyers—or at least they produce a lot of them. There were 1,328,692 licensed and active attorneys in the United States in 2020. This was a 1.7% decrease since 2019, only the second decrease since the American Bar Association started recording data in 1878.

Known as "14ers" among mountain climbers and outdoor enthusiasts, the United States is home to 96 mountains that clock 14,000 feet or more in elevation. Of those, 53 are found in Colorado and 29 are found in Alaska. The other mountains are all found in Washington and California. Alaska holds the 16 highest peaks, with Mt. Denali being the tallest at 20,320 (and the only one to surpass 20,000 feet).

According to Forbes' list of the world's richest people from 2021, the United States is home to 724 billionaires. The 50 wealthiest people on that list hold as much wealth as half of the United States, and since the COVID-19 pandemic tanked the economy in March 2020, America's billionaires have grown their wealth by more than $1 trillion—more than the last $900 billion relief bill.

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.

In 2020, the United States comprised of approximately 128.45 million households, defined as a group of people living in a single housing unit. The housing unit could be a house, apartment, or room, as long as that room is meant to be a separate residence. The figure has doubled since 1970 when there were only 63 million households in the country. According to the U.S. Census Bureau, the average household size is now 2.53 people.

In June 2021, Statistica reported there were 462 commercial casinos operating in the United States, down from 465 in 2019. In Nevada alone, there are 138 casinos that generate $6.52 million or more in annual revenue. Even with institutions numbering in the mere hundreds, gambling is a huge industry. In 2017, for instance, commercial gaming raked in more than $40 billion in revenue. The casino industry was hard-hit during the COVID-19 pandemic, and high numbers of coronavirus cases in Nevada were tied to the state's casinos reopening in August 2020.

About 580,466 people were homeless on one single night in the United States in 2020, according to the U.S. Department of Housing and Urban Development. The agency's Annual Homeless Assessment Report indicated that roughly 0.17% of the population was homeless on any given night. The figure represents the first increase since 2010, with Los Angeles and New York City being among the cities most affected. With unemployment and an ongoing eviction crisis due to the COVID-19 pandemic, the number of people experiencing homelessness in 2021 is expected to rise.

Although times have changed and the age of cell phones has mostly replaced landlines and pay phones, there are still a few lone booths hiding out in random nooks and crannies of America. According to the Federal Communications Commission, there were still about 100,000 pay phones in operation in the United States in 2018. New York is home to roughly one-fifth of those phones, which brought in $286 million in revenue in 2015.

With 23,801 locations in the United States in 2019, Subway is the largest restaurant chain in America. The number dwarfs McDonald's, which had 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.

From coast to coast, there were 60,138 bars serving drinks in America as of July 2021. The industry had previously experienced negative growth of -1.9% from 2015 to 2020.

America's wild and scenic rivers are famous worldwide for their beauty. Although the exact number is unknown, there are at least 250,000 rivers flowing throughout the United States. They total more than 3.5 million miles—enough to stretch to the moon and back seven times. The longest river in the country is the Missouri River at 2,341 miles in length, although the volume of the Mississippi River is greater due to its depth.

The Bureau of Justice Statistics indicates that, in 2016, there were more than 12,000 police departments in operation throughout the United States. The number includes tribal police but does not include sheriffs' offices, which are typically run by counties or other state subdivisions rather than local governments.

There were 2,504 inmates on death row as of the spring of 2021, down from 2,553 inmates in the fall of 2020, according to an NAACP report. However, executions, sentence reversals, and deaths by other causes have resulted in declines in the death row population. More than 55% of those facing execution in 2020 were Black or Latinx, and a majority of death row cases originate in 2% of U.S. counties. 

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 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.

In 2019, the U.S. Census Bureau indicated that there were approximately 17.4 million veterans living in America. That number has since risen, according to data from the Department of Veterans Affairs, which indicated in 2021 that there are around 19 million veterans in the United States. The Department of Veterans Affairs, which has 1,255 health care facilities throughout the country, serves roughly 9 million veterans. The agency offers services such as mental health treatment, physical therapy, prosthetics, dental exams, urology, and vision care.

Linguistically speaking, America is a strikingly diverse place where hundreds of languages converge.

The retail giant has more than 5,000 stores in operation that employ almost 1.5 million people. Of those stores, 3,570 are considered "supercenters," while the rest are broken down into discount stores, neighborhood markets, small-format stores, and Sam's Clubs. In the fiscal year 2021, Walmart's global net sales totaled more than $555 billion. A 2018 study found Walmart to be the retailer engaging in the most wage theft against its employees, with $1.4 billion in total settlements and fines going to employees who were affected. Wage theft includes such practices as forcing employees to work "off the clock," refusing to pay overtime wages, violating minimum wage laws, and requiring workers to buy clothing for work without compensation.

Ghost towns in the U.S. vary in nature but typically date back to the Wild West era, from roughly 1880 to 1940, when frontiersmen went in search of gold, silver, oil, and other valuable resources. The exact number is unknown, but one report by Geotab estimates there are at least 3,800 ghost towns spread across the United States.

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 1783 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).

There are more than 6,000 hospitals in the United States, according to 2019 data. The American Hospital Association offers data visualization tools that show information about bed occupancy and locations of community hospitals.

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." Former 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 over 300,000 bald eagles in the lower 48 states.
