How do you measure the worth of a place to live? Is it by economic prosperity or the contentment of the people living there? While the two sometimes go hand in hand, there is more to being a great place to live than having a high rate of economic growth. Some of the factors (but far from all) that lead to a better quality of life include access to high-quality medical care, clean drinking water, green spaces for outdoor recreation, and a good education system. On the other hand, living in places with high poverty rates, fewer adults with a bachelor’s education, and a lower life expectancy may lead to a poor quality of life.
The Human Development Index (HDI) was created by the United Nations Development Programme and is designed to rank a country’s quality of life. To find the 40 best U.S. counties across the U.S. to live in 24/7 Wall St. reviewed data from the HDI. We ranked counties and county equivalents on a combination of three measures — average life expectancy at birth, the share of adults with a bachelor’s degree or higher, and poverty rate. Data used to calculate rankings are from the U.S. Census Bureau’s 2022 American Community Survey and County Health Rankings & Roadmaps, a joint program of the Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute. All ACS data are five-year averages, and this is the most up-to-date data at this time. Counties with incomplete data were excluded from the analysis. To avoid geographic clustering, we only included one county per metropolitan statistical area.
These are the 40 best U.S. counties to live in:
