With its plethora of renowned hospitals, it may come as little surprise that Massachusetts is a pretty great state for nurses. In fact, three of the best cities for registered nurses in the country are in the Bay State, according to a new ranking by financial research firm ValuePenguin. Using data from the U.S. Bureau of Labor Statistics, ValuePenguin compared the median salary, cost of living, and location quotient (the concentration of nurses in an area as a percentage of all occupations) for 377 cities reporting data across the country, looking for cities most favorable for nurses. Among the top 10 cities were Lawrence at No. 2, followed by Worcester and Boston, which came in at No. 4 and No. 8, respectively.
