=== Education ===
Education on all levels has been shown to be strongly associated with increased life expectancy.<ref name="Hummer_2013">{{cite journal|vauthors=Hummer RA, Hernandez EM|title=The Effect of Educational Attainment on Adult Mortality in the United States|journal=Population Bulletin|volume=68|issue=1|pages=1–16|date=June 2013|pmid=25995521|pmc=4435622}}</ref> This association may be due partly to higher income,<ref>{{cite web|url=https://www.bls.gov/careeroutlook/2018/data-on-display/education-pays.htm|title=Measuring the value of education : Career Outlook: U.S. Bureau of Labor Statistics|vauthors=Torpey E|website=bls.gov|access-date=2019-03-10}}</ref> which can lead to increased life expectancy. Despite the association, among identical twin pairs with different education levels, there is only weak evidence of a relationship between educational attainment and adult mortality.<ref name="Hummer_2013" />

According to a paper from 2015, the mortality rate for the Caucasian population in the United States from 1993 to 2001 is four times higher{{dubious|date=September 2022}} for those who did not complete high school compared to those who have at least 16 years of education.<ref name="Hummer_2013" /> In fact, within the U.S. adult population, people with less than a high school education have the shortest life expectancies.

Preschool education also plays a large role in life expectancy. It was found that high-quality early-stage childhood education had positive effects on health. Researchers discovered this by analyzing the results of the [[Abecedarian Early Intervention Project|Carolina Abecedarian Project]], finding that the disadvantaged children who were randomly assigned to treatment had lower instances of risk factors for cardiovascular and metabolic diseases in their mid-30s.<ref name="pmid24675955">{{cite journal|vauthors=Campbell F, Conti G, Heckman JJ, Moon SH, Pinto R, Pungello E, Pan Y|title=Early childhood investments substantially boost adult health|journal=Science|location=New York, N.Y.|volume=343|issue=6178|pages=1478–85|date=March 2014|pmid=24675955|pmc=4028126|doi=10.1126/science.1248429|bibcode=2014Sci...343.1478C}}</ref>
