Montgomery County has once again placed among the 500 healthiest communities in the nation, according to a new ranking published by U.S. News & World Report.

To determine which communities in the country are the healthiest, U.S. News & World Report compared more than 3,000 counties and county-equivalents based on how they performed in 84 metrics across 10 health and health-related categories.

Population health weighted the highest.

Montgomery County ranked at No. 93 with an overall population health score of 76. The county improved significantly compared to last year when it ranked at No. 140.

Montgomery County ranked in the top 100 thanks in part to its high ranking in the population health category. It boasts a life expectancy of 80.9 years, which is higher than the national median of 77.5 years.

The county also has a low smoking rate of 14.2 percent, below the national median of 21.1 percent. Meanwhile, the number of people with no health insurance is at 4.6 percent, compared to the national median of 10.6 percent.
