MACo’s 2024 article on County Health Rankings (CHR) revealed that Frederick, Montgomery, and Howard Counties ranked the highest among Maryland
Counties and it appears the results are very much the same for 2025.
The CHR, a collaboration between the University of Wisconsin Population Health Institute and the Robert Wood Johnson Foundation, annually evaluates counties across the U.S. based on more than 30 factors that influence health. These factors include social determinants such as education, employment, housing, physical activity and commuting times. The report emphasizes that where we live, work and play has a significant impact on overall health and well-being. Based on these parameters, Montgomery, Frederick, and Howard counties came out on top for Maryland.
