Below is our list of the top 10 mid-sized counties (population 100k-500k) across the US, that we ranked using indicator data to measure community vibrancy and economic success.


1. Placer County, CA

Outside of Sacramento, California, Placer County is our number one mid-sized county. Placer holds strong scores across all categories, including placing in the top ten percent for investment and sustainability. On top of its unique place in history surrounding the gold mining rush, Placer is also home to North Lake Tahoe and stunning mountains. It is consistently ranked as one of the healthiest counties in California.




2. San Luis Obispo County, CA

San Luis Obispo has a top spot on our list of mid-sized counties, scoring in the top ten percent on investment, sustainability, and talent and above average on diversity and place. Sometimes referred to as SLO CAL®, the county is rich with beautiful natural resources, from Pacific Ocean beaches to the Los Padres National Forest. Home to California Polytechnic State University, the county is also the third largest wine producer in the state, making for strong economic and recreational opportunities.




3. Frederick County, MD

Less than 50 miles from both Washington, DC, and Baltimore, Frederick County performs above average in every indicator area. The county ranks in the top ten percent on sustainability, and strongly promotes renewable energy resources like a solar co-op within the community. With historic Civil War sites, the Appalachian Trail, breweries, and orchards abounding, Frederick County is “where hip meets historic every day.”
