The Most Profitable Industry in Each State

More than half of the states in the U.S. are driven by three leading industries: machinery, aerospace, and mineral resources. These findings, shown on a map created by HowMuch (click the link to zoom in), paint a picture of the products and technologies that fuel the country’s economic growth.

And according to HowMuch, a cost information website, the findings are “unnerving.”

“We read all the time about how diversification is the best guard against risk. And based on our map, the US economy is diverse in some regions but not very diverse in others,” HowMuch wrote in a post, noting that 27 states are led by the three aforementioned industries.

“That means that when certain segments undergo technological disruption or economic downturns, it can disproportionately impact sections of the country in ways people don’t expect.”

HowMuch used recent findings from GoBankingRates, which pulled 2017 data from the U.S. Census Bureau data, to create its map. Some of the findings were more predictable, like the fact that states in the Motor City region surrounding Detroit—Michigan, Ohio, and Indiana—get their biggest economic boost from car manufacturing. Others, like Kansas’s $2.6 billion aerospace industry, are perhaps more unexpected.

There is some overlap between the most lucrative industry in each state and the biggest export in each state, which was also mapped out by HowMuch. However, there are a few notable differences. At $20 billion, the most profitable industry in Nevada, for instance, is accommodation and food services (think Las Vegas), while its largest export is gold ($6.3 million).

The Oldest Schools in Each Country

Schools across the globe have been around for centuries.

Online Schools Report

There's something about a school or university with a long history that amplifies its reputation. Well-established institutions of higher learning feel like they have centuries of information to impart—and sometimes, they do.

The online university consultants at Online Schools Report recently compiled data looking at the oldest schools and universities still in operation in every country. You might be surprised how far back some of these schools go. (Click on the maps to see them in full size.)



The oldest is Shishi High School in China, which was established around 141 BCE. England’s King’s School Canterbury opened in 597 AD. Tunisia’s Université Zitouna existed in 737 AD, while Germany’s Gymnasium Paulinum debuted in 797 AD.

Overall, Europe has 19 schools that are more than 500 years old and Africa has four universities that are over 1000 years old.


In North America, the Collegiate School in New York opened its doors in 1638, when New York was still known as New Amsterdam. (The name of the state changed in 1664.)


In Europe, the University of Bologna, which was established in 1088, might have been the first to use universitas, or university, to refer to teachers and scholars.


In Africa, there’s been some debate over whether the Université Zitouna is the world’s oldest university, but only because it was reformed and renamed in the 20th century, interrupting the concept of oldest continuously operating institution.
