In June 2026, Boston announced it would commit $1 million annually to confront a problem that rarely shows up on a map but plays out in everyday life. At the city’s first Black Men’s Health Activation Summit, officials revealed that Black men in Boston live roughly nine years less, on average, than every other group in the city, according to WGBH.
Boston is far from alone. Across the country, Black life expectancy continues to trail most other racial and ethnic groups, and the reasons behind that gap are complex, layered and largely tied to conditions far beyond individual control.
How life expectancy varies by group
According to data from KFF, life expectancy in 2023 differed significantly depending on race and ethnicity. Asian Americans had the longest life expectancy at 85.2 years, followed by Hispanic Americans at 81.3 years and White Americans at 78.4 years. Black Americans lived to about 74 years on average, while American Indian and Alaska Native populations had the shortest life expectancy at 70.1 years.
Researchers stress that these numbers are not rooted in biology. Instead, they reflect income levels, access to insurance, neighborhood conditions and exposure to discrimination, all of which shape health outcomes far more than genetics ever could.
The leading causes of death
CDC data from 2024 identifies heart disease, cancer and unintentional injuries as the top three causes of death among Black Americans. Black Americans are roughly 30 percent more likely to die from heart disease than White Americans, and cancer disparities follow a similarly troubling pattern.
Black men face prostate cancer at rates roughly 70 percent higher than White men and die from the disease at nearly twice the rate. Homicide also ranks among the leading causes of death for Black Americans, largely tied to disparities in gun violence, and together these factors helped make the overall death rate highest for Black Americans in 2024.
Where the average lifespan stands today
As of 2023, the average life expectancy for Black Americans at birth was about 74 years, according to federal data analyzed by KFF. That number has been climbing again after the pandemic, rising by 2.8 years between 2021 and 2023 as COVID-19 deaths declined sharply.
Even with that progress, the figure remains below the national average of roughly 78.4 years. It also varies widely within the population. Black women tend to live longer than Black men, mirroring a gender gap seen across all demographic groups, and geography plays a major role, with life expectancy shifting significantly from one city or neighborhood to another.
The science behind the gap
Public health researchers point to a concept known as weathering to help explain the disparity. First described by scholar Arline Geronimus and recognized by the CDC, the weathering hypothesis suggests that chronic stress caused by racism gradually wears down the body, accelerating biological aging and increasing the risk of illness and early death.
Experts note that education and income alone do not eliminate these risks, even for highly accomplished individuals. A peer reviewed study on residential segregation found that segregation alone accounts for roughly 16 additional years of gap between Black and White men and about five years for women, with more than 90 percent of the national disparity traced back to conditions within individual counties, particularly healthcare access, safety and public health resources.
Why personal choices are only part of the story
Health experts caution against framing the gap as simply a matter of willpower. Many patients delay care due to a lack of insurance, transportation or trust in the medical system, while chronic stress quietly contributes to higher rates of hypertension, heart disease and diabetes over time.
Mental health is also part of the picture. At Boston’s summit, behavioral health officials noted that Black men report high rates of persistent sadness but often avoid seeking care, in part because the healthcare system has not always felt safe or welcoming.
Habits that can help close the gap
Despite the structural challenges, daily habits can meaningfully extend lifespan. A study published in Circulation tracked five lowrisk behaviors, including never smoking, staying physically active for at least 30 minutes a day, eating a high quality diet, maintaining a healthy weight and drinking alcohol only in moderation.
People who followed all five habits by age 50 lived an estimated 14 additional years for women and 12 additional years for men compared with those who followed none, with each added habit contributing roughly two more years. Regular checkups, early screenings and consistent care round out the strategies experts recommend.
The bottom line
The racial lifespan gap in America remains significant, driven largely by access to healthcare, economic opportunity and the long term effects of chronic stress tied to racism. Encouragingly, the gap has narrowed before and is beginning to close again, and cities like Boston are now backing that progress with direct investment alongside individual efforts to build healthier, longer lives.
