Key findings

Data from the National Vital Statistics System, Mortality

• Between 2000 and 2014, life expectancy increased by 3.6, 2.6, and 1.4 years, respectively, for non-Hispanic black, Hispanic, and non-Hispanic white persons.
• The 1.4-year increase in life expectancy for non-Hispanic white persons would have been greater if not for increases in death rates due to unintentional injuries, suicide, Alzheimer’s disease, chronic liver disease, and hypertension.
• Increases in death rates due to unintentional injuries, suicide, and chronic liver disease were large enough to increase all-cause non-Hispanic white death rates for ages 25–34, 35–44, and 45–54.
• Increases in death rates due to unintentional poisonings for ages 25–34, 35–44, and 45–54 had the greatest impact on the change in life expectancy for non-Hispanic white persons.

Between 2000 and 2014, life expectancy at birth in the United States increased by 2.0 years (1,2). The non-Hispanic black population experienced the greatest gain, followed by the Hispanic population. The non-Hispanic white population experienced the smallest gain. Changes in life expectancy over time are directly affected by increases and decreases in age-specific death rates and age-specific cause of death rates. In this report, the relationship between increases in all-cause age-specific and cause-specific death rates and the change in life expectancy for the non-Hispanic white population between 2000 and 2014 is explored.

The increase in life expectancy at birth between 2000 and 2014 varied by race and Hispanic origin.

• Between 2000 and 2014, life expectancy for the total population increased by 2.0 years (Figure 1).
• Life expectancy at birth increased by 3.6 years for the non-Hispanic black population (from 71.6 years in 2000 to 75.2 years in 2014) and by 2.6 years for the Hispanic population (from 79.2 years in 2000 to 81.8 years in 2014).
• Life expectancy for the non-Hispanic white population increased by 1.4 years (from 77.4 years in 2000 to 78.8 years in 2014).

The change in life expectancy at birth for the non-Hispanic white population from 2000 to 2014 was due to increases in death rates for some causes of death and to decreases in others.

• The decrease in death rates due to heart disease, cancer, stroke, pneumonia, and aortic aneurysm contributed 1.928 years to the change in life expectancy at birth (Figure 2).
• The increase in death rates due to unintentional injuries, suicide, Alzheimer’s disease, chronic liver disease, and hypertension contributed a loss of 0.419 years to the change in life expectancy.
• Unintentional injuries, suicide, and chronic liver disease contributed a loss of 0.337 years in life expectancy.

The change in life expectancy at birth for the non-Hispanic white population from 2000 to 2014 was due to increases in death rates for some specific age groups and to decreases in others.

• The decrease in all-cause age-specific death rates for ages 0–1, 1–4, 5–14, 15–24, 55–64, 65–74, 75–84, and 85 and over contributed 1.618 years to the change in life expectancy at birth (Figure 3).
• The increase in all-cause age-specific death rates for ages 25–34, 35–44, and 45–54 contributed a loss of 0.182 years to the change in life expectancy.

Death rates due to unintentional injuries, suicide, and chronic liver disease in ages 25–54 increased for the non-Hispanic white population from 2000 to 2014.

• Death rates due to unintentional injuries increased 63.3% for ages 25–34, 41.5% for ages 35–44, and 73.5% for ages 45–54 (Figure 4).
• Death rates due to suicide increased by 37.3% for ages 25–34, 30.2% for ages 35–44, and 57.5% for ages 45–54.
• Death rates due to chronic liver disease increased by 30.9% for the age group 45–54.

Death rates for chronic liver disease and cirrhosis for ages 25–34 and 35–44 are not shown due to very small death rates (ages 25–34) and no statistical change over time (ages 35–44).

The change in life expectancy at birth for the non-Hispanic white population from 2000 to 2014 was due to increases in death rates for some subcategories of unintentional injuries and decreases in others.

• The decrease in death rates due to motor vehicle, other transport, unintentional fire, water transport, unintentional drowning, other land transport, and unintentional firearms contributed 0.197 years to the change in life expectancy at birth (Figure 5).
• The decrease in deaths from motor vehicle accidents contributed the most (0.153 years).
• Unintentional poisonings (mostly drug and alcohol poisoning) had the greatest contribution to the change in life expectancy for the non-Hispanic white population with a loss of 0.338 years.

Summary

Between 2000 and 2014, life expectancy at birth increased by 1.4 years for the non-Hispanic white population in comparison with 2.6 years for the Hispanic and 3.6 years for the non-Hispanic black populations. In fact, for the first time in over 20 years, life expectancy declined by 0.1 years for the non-Hispanic white population between 2013 and 2014 (1,2). This finding led to the question of whether the rise in mortality from suicide, drug and alcohol poisoning, and chronic liver disease over the period played a role in the relatively small increase in life expectancy for the non-Hispanic white population (3).

The increase in life expectancy for the non-Hispanic white population was positively affected by decreases in death rates due to heart disease, cancer, stroke, pneumonia, and aortic aneurysm. On the other hand, increases in death rates due to unintentional injuries, suicide, Alzheimer’s disease, chronic liver disease, and hypertension had negative effects on the change in life expectancy. Increases in cause-specific death rates from only three causes—unintentional injuries, suicide, and chronic liver disease—were large enough to affect the all-cause death rates for the non-Hispanic white population in the age groups 25–34 (27.6% increase), 35–44 (2.7% increase), and 45–54 (7.0% increase). No other cause, including Alzheimer’s disease, had a large enough influence to affect all-cause age specific death rates. Increases in death rates due to unintentional poisonings (mostly drug and alcohol poisoning) for these three age groups had the single greatest negative effect on the change in life expectancy.

Increases in mortality due to unintentional poisonings, suicide, and chronic liver disease directly affected the change in life expectancy over the past 15 years for the non-Hispanic white population.
