The 10 Dumbest Places In Louisiana For 2026

The unfortunate fact of the matter is that some places in the Pelican State have a larger percent of their population that never graduated from high school.

While the emphasis on going to college might be overblown, the fact is that not graduating from high school puts you at a significant disadvantage on average. Educational attainment might not be the best way to measure one person’s intelligence, but it does shine a light on the state.

We will use Saturday Night Science to determine what places in Louisiana have the highest percentage of adults without a high school degree.

A recent study we published found that Louisiana is the 49th smartest state in the United States, with an average IQ of 95.

But that doesn’t mean that a few cities in Louisiana are a bit slower than others due to a lack of basic education.

Methodology: How we determined the dumbest cities in the Pelican State

We realize that formal education is only part of it when it comes to being intelligent, but on the other hand, knowing the difference between they’re, their, and there is always going to make you look pretty stupid.

So, we used Saturday Night Science to narrow down our criteria to focus on a city’s educational opportunities and what percentage of the population takes advantage of those opportunities.

In short, we came up with these criteria to determine the dumbest cities in Louisiana:

• % of the city’s population with less than a high school education (Age 25+)
• % of city’s population with a college degree (Age 25+)

We got the data from the U.S. Census 2020-2024 American Community Survey.

Then, our algorithm generates a rank for each place in these categories. After crunching all the numbers, a ranking of the cities in Louisiana from dumbest to brightest.

For this ranking, we used every Louisiana city with at least 5,000 residents. We updated this article for 2026, and it’s our eleventh time ranking the dumbest cities in Louisiana.
