UNDATED  (WSAU)  -  Wisconsin’s business climate is the 13th best in the nation. That’s according to a new survey by Site Selection magazine. The magazine deals with corporate real estate strategies and economic development. Editor Mark Arend said the Badger State made a big improvement recently. He said Wisconsin has not been in the Top-25 for several years. North Carolina ranks as the top state for businesses to locate. Ohio was second, followed by Texas. The states are ranked according to their tax burdens, numbers of new-and-improved business facilities, and opinions from those who select locations for companies.
