As of April 2025, there have been 16 measles outbreaks in the United States, a number that has jumped significantly over the past few years. A new study from PA Requirements shows this has a connection to vaccination gaps. Kindergarten vaccinations help protect citizens against diseases like measles and contribute to our population achieving herd immunity, which eradicates the threat of the disease. However, the team’s study reveals that a combination of policy, vaccine access, and community factors is hindering our progress toward this goal.

The team found that these states had the highest percentage of children not vaccinated for measles:

• Idaho: 20.4%
• Alaska: 15.7%
• Wisconsin: 15.2%
• Minnesota: 13.0%
• Florida: 11.9%
• Oklahoma: 11.7%
• Colorado: 11.7%
• Utah: 11.2%
• Iowa: 10.9%
• Ohio: 10.8%

It can be useful to compare these numbers to the states with the lowest rates of unvaccinated children:

• West Virginia: 1.7%
• New York: 2.3%
• Connecticut: 2.3%
• Mississippi: 2.5%
• Maine: 2.5%
• Rhode Island: 2.9%
• Maryland: 3.4%
• Massachusetts: 3.7%
• California: 3.8%

We can observe some interesting regional patterns by examining the map, such as lower vaccination rates in the Midwest and Southwest.

Among the states with high rates of vaccination, we find that these five states don’t allow non-medical vaccination exemptions: Maine, New York, West Virginia, Connecticut, and California. It’s no surprise that stricter policies lead to a greater number of vaccinations. Among states with lower rates, we find more relaxed laws that allow for greater exemptions on the basis of religion, philosophy, and other personal reasons. Comparing each state to its neighbors reveals patterns and trends that might imply cultural differences affecting vaccination rates in different regions. We can look for locations with a high prevalence of religions that outlaw vaccines to identify reasons for the numbers on the map. Check the numbers on the states with the largest cities, and you might find stricter vaccination laws there to help prevent disease spread in population-dense areas.

There’s no doubt that state policies correlate directly with vaccination rates when we look at the numbers presented on the team’s graphic. Many states require certain vaccinations, like measles, in order to enroll in public school. These laws and requirements also directly impact vaccination rates. Looking at insurance costs and access to vaccine clinics in rural areas may also reveal why some areas have more unvaccinated children than others. Some states have created initiatives to encourage vaccination and provide education, leading to higher vaccination rates.

Overall, studies like these greatly benefit public health by increasing awareness and education about diseases like measles. People who shy away from vaccines often find them untrustworthy. The only way to convince them otherwise is to answer their questions and present them with transparent data that’s easy to understand, just like the information shown in this graphic, regarding the risks associated with declining vaccines. These studies provide policymakers, parents, and public health officials with more information to make informed decisions for the health of their children and communities.

There are more than 30 million businesses in the U.S. — but some of those companies employ far more workers than others. Giants like Walmart and Amazon have more than a million employees working on developing, marketing, transporting and selling their products everyday. Meanwhile, lesser-known companies in industries you may not be as familiar with also employ a significant amount of our workforce.

Using Fortune 500 data, our team at The Chartistry identified the largest employers in every industry, including retail, food, health care, real estate and many more (we included a whopping 75 industries total).

Who is the largest employer in America?

Technically, the largest employer in the U.S. is the federal government. But if we’re talking about the company that employs the most people, Walmart takes the cake.

Since Walmart’s first store opened in 1962, the company has grown to establish more than 11,500 stores globally to serve more than 260 million weekly shoppers in 28 countries, according to the company’s site. It’s no surprise that the retailer requires a lot of manpower. Walmart has 2,100,000 employees, and is the only one on our list that employs more than 2 million people.

Who else are America’s biggest employers?

Walmart may offer up the most jobs in the U.S.,but there are plenty of other companies with thousands of employees headed to work everyday. Some of the giants on the list of companies with the most employees in every industry are also among the largest U.S. employers in general.

Amazon, which started in Jeff Bezos’ garage in 1994 as an online bookseller, has grown up to make its mark around the world. There’s a good chance you’ve shopped online via the company, watched its streamer or walked past an Amazon retail store or fulfillment center. Amazon may have started with a solo founder, but it now employs 1,525,000 people.

Home Depot is another retail heavyweight. Founded in 1978 as a hardware store, the company now boasts more than 2,300 stores across North America. But offering up all that home improvement requires a lot of hands on deck: The company has 463,100 employees. That makes it the highest employer in one category of specialty retailers, but TJX, with 349,000 employees, is the largest employer in the apparel-specific specialty retailer category.

In the mail, package and freight delivery industry, you can probably guess who employs the most people. It’s FedEx, which was just an idea in 1965 when its eventual founder Frederick W. Smith wrote a paper at Yale University on the potential of a new way to get time-sensitive shipments to recipients (he received an average grade, according to the company’s website). Since then, the company makes around 14.5 million deliveries each day thanks to its 446,400 employees.

UnitedHealth Group also made our list, which makes sense, seeing as its the largest health insurance company in the U.S. Parent company of United Healthcare, the company was founded in 1977. Nowadays, it employs 440,000 people.

Curious which food and drug store is the largest employer? That would be Kroger, which had its start in 1883 when Barney Kroger invested his life savings of $372 to open a single grocery store. More than 140 years later, Kroger is the nation’s largest grocer with nearly 2,800 stores in 35 states and 414,000 employees. But if we’re talking specifically about food services, latte lovers’ favorite place, Starbucks, is the largest employer, with 381,000 employees. Looking specifically at the food consumer products industry, PepsiCo — which owns brands like Lay’s, Doritos, Gatorade, Quaker and, of course, Pepsi — is the largest employer with 318,000 employees.

The travel industry also requires tons of workers. American Airlines Group, which offers thousands of flights daily in more than 60 countries, is the largest employer in the airline industry with 132,100 people. Hilton Worldwide Holdings, meanwhile, has 178,000 employees to help run its hotels, casinos and resorts.

In the entertainment industry, a very familiar name earns the title for largest employer with its 199,125 workers: Walt Disney.

Studying jobs by age groups provides insight into worker priorities and the impact of factors such as education, experience, and physical strength. The team at Qualtrics gathered data to create a graphic of the most common jobs held in different age categories using data from the Bureau of Labor Statistics to form their visualizations.

Click below to zoom.

Here are the most common jobs by age:

• 16–24: cashier
• 25–34: registered nurse
• 35–54: elementary or middle school teacher
• 55–64: sales worker or truck driver
• Over 65: farmer, rancher, or agricultural manager
• Any age group overall: customer service representative

The chart shows that the most common job is a customer service rep, which is understandable given the number of industries hiring for this position. It’s a job with diverse tasks encompassing customer experience and quality of interactions with the business. Customer service jobs typically don’t require more than a high school diploma, yet they pay an average annual salary of over $60,000.

We can see from the charts that cashier and server jobs are most common among the youngest demographics. This is likely due to the low pay and hours spent on your feet. It’s an entry job for many people who grow to move on to different positions or career paths as they age and change priorities. While that’s not always the case, many servers and cashiers move on from the role in search of higher pay and less physically demanding work.

These same individuals may go on to pursue careers as teachers and nurses, if our data is any indication. These jobs require specialized education but offer higher pay, and there is a demand for these positions. It’s no surprise that many people are building lifelong careers in nursing and teaching. As for people who keep working past retirement age, farmers and ranchers took the top spot. This work is often physically demanding, but the businesses are usually generational, meaning older people get help from their descendants and stay involved with a business close to their heart.

Employers can make use of data like this, as they generally want to avoid job-hopping employees. Looking at these statistics, we can infer many reasons why someone may leave a job. Employers can address this by offering higher wages, more flexible work styles and arrangements, and an improved employee experience. Most workers seek a stable job with fair compensation for the amount of work and education required. We also note that many blue-collar jobs are represented on this list, including construction workers, janitors, and truck drivers, with fewer white-collar jobs listed. Many people work essential jobs that help us stay healthy, fed, and stocked with goods.
