Older Men and Women Living Longer

By Joseph Chamie
PORTLAND, USA, Jun 10 2025 – Older men and women are now living longer than ever before. Across the globe, individuals who reach old age can expect to have more years of life ahead of them than in previous generations. However, these additional years of life, coupled with the disparities among and within countries, including variations between older men and women, present substantial economic, social, and political challenges for societies.

Global Trends

In 1950, the world’s average life expectancies for men and women at age 65 were about 11 and 12 additional years, respectively. By 2025, those average life expectancies at age 65 increased by over 50%, reaching about 16 additional years of life for men and 19 additional years for women.

The trend of living longer at age 65 is expected to continue throughout the rest of the 21st century. By 2100, for example, the world’s average life expectancies for men and women at age 65 are projected to be 21 and 23 additional years, respectively, which are double the numbers of additional years of remaining life in 1950 (Figure 1).

The good news about older men and women living longer is also clear at age 80. In 1950, the world’s average life expectancies for men and women at age 80 were approximately 5 years. By 2025, that average life expectancy is estimated to have increased by approximately 50%, reaching close to 8 additional years for men and 9 years for women.

The largest gains and highest levels of life expectancy at older ages are among wealthier, more developed countries. While less developed countries have also gained additional years of life at older ages, their increases have been substantially less than those of the more developed countries, which has contributed to widening the gap between them

As at age 65, the trend of men and women living longer at age 80 is also expected to continue throughout the rest of the 21st century. By 2100, for example, the world’s life expectancies at age 80 for men and women are projected to be approximately 11 and 12 years, respectively.

The gains in longevity at older ages have also increased the differences between men and women. Not only do women live longer than men, but differences in additional years of life at older ages between them have increased during the past seventy-five years.

Country Trends

The largest gains and highest levels of life expectancy at older ages are among wealthier, more developed countries. While less developed countries have also gained additional years of life at older ages, their increases have been substantially less than those of the more developed countries, which has contributed to widening the gap between them.

In Japan and Italy, for example, the current additional years of life for men and women aged 65 are approximately 20 years and 24 years, respectively, or nearly double the levels in 1950. A similar pattern of increase in additional years of life for those two countries took place for men and women at age 80.

In contrast, the current additional years of life of men and women aged 65 in Nigeria and the Democratic Republic of the Congo are about 13 years, which are only several years more than they were in 1950. Also, the improvements in additional years of life for men and women at age 80 since 1950 are relatively modest, typically only a single year of increase (Table 1).

Regarding the future, the additional years of life of older persons among countries are expected to continue increasing worldwide throughout the 21st century. In Japan and Italy, for example, men and women aged 65 years at the end of the century can expect to live approximately 28 and 32 additional years, respectively.

Again, in contrast, the corresponding gains in additional years of life for men and women aged 65 in Nigeria and the Democratic Republic of the Congo are considerably lower. By the end of the century, the additional years of life for men and women aged 65 years in those two countries are around 15 years.

Besides variations across countries, the additional years of life of older individuals also vary significantly within countries.

For example, in the United States, life expectancies of older individuals vary among the country’s fifty states. These variations are mainly because of differences in socioeconomic status, access to healthcare, public health policies, lifestyle factors, and political policies.

In 2021, the highest life expectancies for those 65 years and older were approximately 18 years for males and 21 years for females in Hawaii, Connecticut, Massachusetts, Minnesota, and New York. In contrast, the lowest life expectancies at age 65 were about 15 years for males and 18 years for females in Mississippi, West Virginia, Alabama, Oklahoma, and Kentucky (Figure 2).

Challenges

Additional years of life in old age certainly offer positive news for older men and women and for their families, friends, and communities. Longer lives for older men and women provide them with additional time for learning, adventure, recreation, development, work, and contributions.

However, those additional years of life for older individuals also raise noteworthy challenges.

For example, challenges will arise for public health, housing, work and retirement, healthcare, and elder care. Also, the increased life expectancies for older men and women raise the risks of multiple morbidity, disability, dementia, and degenerative diseases.

At the same time that older people are living longer, fertility rates are declining worldwide, with many countries experiencing below replacement fertility. And because of those low fertility rates, countries are entering uncharted territories of population decline and demographic ageing.

One important consequence of those uncharted territories is declining potential support ratios, i.e., declining numbers of persons aged 20 to 64 years per person aged 65 years or older.

Whereas the world’s potential support ratio was 10 in 1950, it declined to 8.6 by 1975 and declined further to 5.0 by 2025. By 2050, the ratio is expected to be 3.0 (Table 2).

The declining potential support ratios, which are occurring worldwide but are the lowest in more developed countries, raise the important issue of the age for retirement.

Ageing populations, decreasing fertility rates, and declining potential support ratios are impacting the financial sustainability of pension systems. As a result, a common policy strategy of many countries that aims to address the financial viability of their pension systems is to raise their current retirement ages.

As French President Emmanuel Macron has said, “vivre plus longtemps, travailler plus longtemps” (“live longer, work longer”). China is also gradually raising the retirement age to address its shrinking workforce relative to its growing older population.

As with government pension programs, the increasing longevity and growing proportions of older persons are also impacting the affordability and financial sustainability of government healthcare systems.

In particular, the rising prevalence of chronic diseases, such as heart disease, diabetes, and cancer, as well as the need for long-term care services, like nursing homes and assisted living facilities, are rapidly increasing healthcare costs for the growing population of older men and women who are living longer lives.

Conclusions

In conclusion, there are several important points that need to be emphasized. First, older men and women are now living longer than ever before, and this trend of increased longevity is expected to continue throughout the 21st century.

Second, the additional years of life expectancy among older individuals have widened the gap between more developed and less developed countries. While gains in life expectancies for older individuals have occurred worldwide, the largest gains have been seen in the wealthier, more developed countries.

Besides differences among countries, the gains in longevity at older ages also vary within countries. Variations within countries arise mainly because of differences in socioeconomic status, access to healthcare, public health policies, lifestyle factors, and political policies.

Third, the gains in life expectancy at older ages have also increased the differences between men and women. Not only do women live longer than men, but the gap in additional years of life at older ages between them has increased in recent years, particularly in more developed countries.

Finally, the additional years of life for older men and women, combined with population decline and demographic ageing, present important economic, social, and political challenges for governments and their citizens. Challenges will arise in the areas of public health, housing, work and retirement, healthcare, and elder care.
