Skilled Nurses per Resident by Medicaid Certification and Concentration

Notes. The vertical axis measures the number of skilled nurses per resident. Following the merger guidelines from the Federal Trade Commission, the right graph divides counties into highly concentrated (HHI >2,500) and non-concentrated (HHI <1,500) markets. The national data come from LTC Focus in 2010.
