A Global Benchmark
Before the unprecedented impact of the COVID-19 pandemic, 2019 represented a high-water mark for global life expectancy. According to the World Health Organization (WHO), the global average life expectancy had increased by more than six years between 2000 and 2019, reaching 73.1 years in 2019. This remarkable upward trend was a testament to decades of progress in medicine, sanitation, and public health initiatives worldwide. However, this promising progress was swiftly undone by the pandemic, making the 2019 figures a significant benchmark for measuring future recovery.
The United States in 2019
In the United States, life expectancy also showed an upward trend leading into 2019. The Centers for Disease Control and Prevention (CDC) reported that the overall U.S. life expectancy at birth was 78.8 years. This figure marked a slight increase of 0.1 years from 2018, continuing a trend of gradual improvements. This overall figure, however, masked significant variations based on gender and racial or ethnic groups.
Life Expectancy Disparities
In 2019, a closer look at the data reveals notable differences in life expectancy across various demographic groups. In the U.S., women consistently outlived men. The CDC reported that in 2019, the life expectancy for females was 81.4 years, compared to 76.3 years for males, a gap of 5.1 years.
Beyond gender, racial and ethnic disparities remained a critical issue. Data from the CDC indicated the following life expectancies in the U.S. in 2019:
- Non-Hispanic Asian: 85.6 years
- Hispanic: 81.9 years
- Non-Hispanic White: 78.8 years
- Non-Hispanic Black: 74.8 years
- Non-Hispanic American Indian or Alaska Native (AIAN): 71.8 years
Geographic location also played a role, with studies showing differences between urban and rural areas. Higher rates of crime, pollution, and inadequate access to healthcare and nutritious food in certain communities contributed to these disparities.
Factors Influencing Longevity in 2019
Several factors contributed to the overall life expectancy figures observed in 2019. Public health experts point to ongoing advancements in medicine, improved sanitation, and lifestyle factors. The ten leading causes of death in 2019, such as heart disease and cancer, remained consistent with 2018, though their rates changed slightly. Decreases in mortality rates from cancer, chronic lower respiratory diseases, and influenza contributed to the modest increase in overall life expectancy.
Furthermore, socioeconomic factors continued to be influential. A country's economic stability, public health infrastructure, and access to education all correlate with higher life expectancy. Health behaviors, such as diet, exercise, and smoking, also play a significant role.
2019 Life Expectancy: A Comparison
To put the U.S. 2019 life expectancy into a broader context, it's helpful to compare it with other high-income countries. This reveals how various healthcare systems and public health strategies influenced national longevity.
| Country | U.S. Life Expectancy (2019) | Comparable Country (Example) | Life Expectancy at Birth (approx. 2019) | Notes |
|---|---|---|---|---|
| United States | 78.8 years | Japan | 84.6 years | Known for a diet rich in fish and vegetables, strong preventative care. |
| United States | 78.8 years | Switzerland | 83.5 years | Benefits from a well-developed healthcare system. |
| United States | 78.8 years | Canada | 81.3 years (in 2022, after declines) | Universal access to healthcare is a key factor. |
| United States | 78.8 years | OECD Average | 80.7 years (in 2019) | The U.S. ranked below many other developed nations. |
This comparison highlights that despite the overall positive trend in 2019, the U.S. lagged behind many peer nations, a gap exacerbated by the subsequent pandemic.
The Future of Longevity
Studying the 2019 life expectancy provides valuable lessons for addressing future public health challenges. The pandemic underscored the fragility of longevity gains and highlighted persistent inequalities. As public health efforts focus on rebuilding and improving upon pre-pandemic health metrics, understanding the trends and disparities of 2019 is crucial. Strategies must address the systemic issues revealed by the pandemic, from unequal access to healthcare to socioeconomic determinants of health, to foster more equitable and resilient health outcomes for the future.

Conclusion
In summary, 2019 was a year that marked a peak in recent global and U.S. life expectancy, reflecting continued progress in health and medicine. However, this data also clearly illustrated ongoing disparities tied to gender, race, and socioeconomic status. The pre-pandemic snapshot of 2019 offers a vital reference point for evaluating the long-term effects of global health crises and guiding future strategies aimed at improving longevity for all.
