GILLETTE, Wyo. (AP) — A research firms ranks Gillette as the nation's fourth-strongest economy out of 576 cities around the nation with between 10,000 and 50,000 residents.

Sheridan is just behind at fifth.

Florida-based Policom specializes in analyzing local and state economies and ranks both big cities and small cities.

The research firm takes into account multiple factors when creating the rankings, including jobs, per capita personal income, how the local economy is behaving and population growth trends.

Gillette has made Policom's top 10 list five years in a row.

City Administrator Carter Napier tells the Associated Press  that the ranking is an indicator that things are going well in Gillette and are moving in the right direction.
