A new report ranks the healthiest counties in every state, and it's good news for many who live in Maryland and northern Virginia.

The University of Wisconsin Population Health Institute and the Robert Wood Johnson Foundation compiled the second annual County Health Rankings report. It looks at various health factors such as tobacco use, obesity, and access to health care and air quality. Counties are then scored and ranked within each state.

In Virginia, Fairfax County placed first on a list of 132 cities and counties. Arlington County took second place, and Loudoun County third. Alexandria City, Fairfax City and Manassas City also made the top 10.

In Maryland, Howard, Montgomery and Frederick counties ranked first through third, respectively. Prince George's County didn't fare so well, coming in at No. 17.

Robert Wood Johnson Foundation President and CEO Dr. Risa Lavizzo-Mourey said the report shows that, "where you live, learn, work and play makes an incredible difference to your health." The report is also intended to give communities a road map to improve overall health.
