At a time when the Affordable Care Act and an aging Baby Boom generation could combine to create greater demand for nurses nationwide, Mississippi is the most ill-prepared state in the union to handle the nursing industry's shifting job market, a new study finds. Financial website WalletHub measured each state and the District of Columbia through 15 metrics, including job opportunities in each state, competition for each job opening, differences in workplace environment and future jobs projections. Mississippi ranked 51st overall in the study and didn't fare much better in key individual metrics, finishing in the bottom 10 in job opportunities, competition for each opening and work environment.
