"Education Saves Lives": A New Study Links Learning to Longevity, Another Aspect of Public Health

"Education is for future employment."
Many people think this way. To get better jobs, increase income, and expand choices in society. Education is often discussed in connection with economic success and social status.

However, the latest international research brings the meaning of education to a deeper level. Education is not merely about acquiring the ability to earn. It is directly related to the possibility of living longer and healthier lives—this is the strong message conveyed by the study.

In a new study involving researchers from the University of Manchester, mortality rates from 1980 to 2015 were analyzed across 13 countries in Southeast Europe, West Asia, and North Africa. The focus was on age, gender, and education level.

The research team focused on the question, "How much does the difference in education levels affect a person's lifespan?" The conclusion was clear. People with more years of education or higher education levels consistently showed lower mortality rates and tended to live longer.

Particularly striking was the point that, in some countries, the difference in average life expectancy due to education levels reached over 10 years. Ten years is not just a statistical difference; it is time to witness a child's growth, continue working, spend with family, and choose how to live the latter half of life. Educational disparities may manifest not only as income or occupational gaps but also as "gaps in the time one can live."

The importance of this study also lies in its target regions. The relationship between education and longevity has been studied mainly in developed countries. However, in countries or regions where birth and death registration systems are not well established, reliable data is often lacking. Therefore, it has been difficult to accurately grasp the impact of education on health and longevity on a global scale.

To overcome this barrier, the research team developed a new statistical model to estimate mortality rates by combining multiple incomplete data sources. They integrated international data from the United Nations, Eurostat, and Demographic and Health Surveys to reconstruct mortality rates by age, gender, and education level. The significance of this study lies in its attempt to reveal a reality as close as possible, even from incomplete information, rather than saying it is unknown due to the lack of complete statistics.

The most noticeable differences in the study were among women aged 20-49. Women with secondary education or higher showed a tendency to have lower mortality rates compared to those with little education. This is not simply a matter of "going to school makes you healthier." Receiving education makes it easier to gain knowledge about health, increases the ability to access medical services, expands income and occupational choices, and facilitates informed and confident decision-making in life aspects such as marriage, childbirth, work style, medical institution use, and children's health management.

Education is not just about acquiring literacy and numeracy. It also connects to the ability to understand changes in one's body, interpret doctors' explanations, choose to leave hazardous work environments, and reach systems and support. In other words, education is an "invisible infrastructure" built within individuals.

In this sense, education can be considered an important element of public health, just like hospitals and medicine. People rely on medical care after becoming ill. However, lifestyle habits that reduce the risk of illness, decisions to avoid dangerous environments, and actions to seek early medical consultation are influenced by daily knowledge and social resources. Education lays that foundation.

Of course, it should not be simplistically understood as "education guarantees longevity." People with high education levels may have been born into wealthy families, live in safe areas, have good nutrition, have parents with high education levels, and have favorable access to healthcare. Education is both a cause and a result of broader socioeconomic conditions.

In fact, this point is often highlighted in reactions on social media and forums. Although the article itself did not see significant engagement on Phys.org shortly after its release, it was introduced with the headline "Education Can Save Lives" on a Chinese-language overseas news aggregation site, indicating it is a topic of international interest.

Additionally, when a chart with the theme "Going to College Extends Your Life by 10 Years" was shared on Reddit in the past, it sparked quite a realistic discussion. One user pointed out that more than college education itself, it is the ease of getting jobs with health insurance and less physical burden that matters. Another user commented that multiple factors such as income, stress, diet, smoking, drinking, drug dependence, and medical access are intertwined.

Some reactions included, "Isn't this correlation rather than causation?" In other words, the question arises whether it is not that education leads to longer life, but rather that people in environments conducive to longevity are more likely to receive education. This question is important. In social science and public health research, confusing correlation with causation can lead to incorrect policy decisions.

However, this does not provide a reason to disregard education. Education influences many factors such as income, occupation, health behavior, medical access, social networks, and self-efficacy, making it an "upstream" condition. Even if education itself is not the sole cause, improving education could simultaneously strengthen multiple pathways that support health.

What this study indicates is that education should not be confined to "school policy" alone. Investment in education is employment policy, poverty alleviation, gender equality policy, and public health policy.

For example, expanding access to secondary education for women could affect not only their health but also the health of their children, family nutrition, and regional medical utilization. Literacy, understanding health information, and accessing administrative services are connected to infectious disease control, maternal care, and chronic disease prevention. Education, though it may seem like an individual benefit, actually strengthens the health foundation of society as a whole.

On the other hand, society should not be one where only those who are educated can live healthily. This study is not meant to reinforce a self-responsibility argument of "just get more education." Quite the opposite. If differences in educational opportunities can lead to differences in lifespan, then ensuring equitable educational opportunities becomes a policy challenge to reduce inequality in life.

As discussed on social media, if there is a social structure where people with low education levels tend to concentrate in dangerous jobs or unstable employment, then not only school education but also working conditions, wages, health insurance, regional safety, and food environments need to be reviewed simultaneously. Education is not a panacea. However, it is a very powerful indicator and intervention point for measuring social health disparities.

Another value of this study is that it sheds light on regions with scarce data. When considering global health disparities, looking only at data from countries with well-established statistics may overlook certain populations. In regions where births and deaths are not accurately recorded, problems may exist but not appear as numbers. What doesn't become a number is often left out of policy priorities.

The model developed by the research team is an attempt to visualize these "invisible disparities." If the relationship between education and mortality can be estimated by age and gender, it allows for more specific consideration of which groups need what kind of support. For example, if educational disparities strongly appear in the mortality rates of young women, policies combining girls' education, maternal care, community health, violence prevention, and economic independence support may be necessary.

Another large-scale meta-analysis published in 2024 also estimated that each additional year of education reduces adult mortality risk by about 2% on average. Results reported that six years of education reduced mortality risk by about 13%, 12 years by about 25%, and 18 years by about 34%. Although the research methods and target regions differ, this provides additional evidence that "the relationship between education and mortality is not a coincidental regional phenomenon."

Discussions around education often focus on short-term cost-effectiveness. How much does it cost to build schools? Is there funding to increase teachers? How much budget can be allocated to scholarships, school meals, and commuting support? However, if education affects future medical costs, labor participation, family health, and longevity, the cost-effectiveness calculation needs to be done over a much longer time frame.

Being able to attend school sets the starting line for life. And the difference in that starting line could reappear decades later as differences in health status and lifespan.

This study provides a calm statistical backing to the common saying, "Learning enriches life." Education is not just about increasing knowledge. It expands choices, reduces risks, protects health, and extends the time of life.

Therefore, education policy is not just a matter for children. It is an issue that affects how long, healthily, and with dignity society as a whole can live. What happens in school classrooms is connected to future hospitals, homes, workplaces, and communities.

Investing in education is investing in life.
The message from this study is simple yet profound. If we are serious about aiming for a long-lived society, we need to look not only at the healthcare system but also at the classroom.
