When it comes to income inequality, southern states appear to have it the worst.

• Income inequality measures the gap between the richest people and the rest of the population.
• In the US, southern states and high-population states tend to have the worst levels of income inequality.

The gap between rich Americans and poor Americans has been a cause for concern in the United States for decades.

But although that gap has gotten significantly worse since the 1970s, income inequality is not the same across each state.

Careers data site Zippia used data from the US Census Bureau's American Community Survey to rank all 50 states by income inequality.

The states are ranked by their Gini coefficient, a commonly used metric that quantifies income inequality on a scale from one to 100. The lower the score, the more equal the income distribution - a score of 100 would mean that one person controls all the wealth in an economy.

As a country, the US fares pretty poorly when it comes to income inequality: according to the CIA Factbook, the US has the 40th highest level of inequality out of 150 countries - around the same level as Jamaica, Peru, and Cameroon.

Within the US, there are some clear trends: the states with the least inequality tended to be western states and states with low populations, while the most inequality occurred in high-population states and southern states.

The results line up with previous research that showed that people in the South have much lower odds of moving from the lowest income bracket to the highest, and that people in the West have the best chances of doing the same.

Analysis from political geographer Richard Morrill showed that areas like the South, where income inequality was more pronounced, also have high minority populations. Meanwhile, heavily homogenous areas with high Germanic and Scandinavian populations - like the West - tended to have the most income equality, he found.
