The US is the richest nation in the world, with an annual GDP of $17.3 trillion in 2014. However, some states are greater contributors to the economy than others. To illustrate differences among state economies, the folks at HowMuch.net created a chart that shows the relative economic value of each US state.

The states are also color-coded based on which region of the country they’re in.

The three regions that contribute the most to the economy are the Far West (18.6%), Southeast (21.3%), and Mideast (18.2%). California (13.3%), Texas (9.5%), and New York (8.1%) have the largest economies in the country.

Maine, Rhode Island, North Dakota, South Dakota, Montana, Wyoming, and Alaska all represent about 0.3% of the US economy each, and, at 0.2%, Vermont has the smallest economy of all 50 states.
