Reason for Ranking
The relationship between higher education and improved health outcomes is well known, with years of formal education correlating strongly with improved work and economic opportunities, reduced psychosocial stress, and healthier lifestyles.
Measurement Strengths and Limitations
Different aspects of education have been studied in an attempt to distinguish which factor or factors play the most significant role in the health of the population. Years of formal education has the strongest correlation with health and is thought to be related to work and economic opportunities, psychological resources, and a healthier lifestyle.
A limitation of this measure is that it groups people with varying educational backgrounds. In so doing, it may underestimate or overestimate the health benefits that post-secondary education confers on a given county depending on the amount of post-secondary education residents have attained.
