Mortality in the United States, 2017

November 29, 2018

Questions and Answers from the authors of the recently released 2017 mortality data.  The data can be found in the following reports, “Mortality in the United States, 2017, ” “Drug Overdose Deaths in the United States, 1999–2017, ” and “Suicide Mortality in the United States, 1999–2017.”

Q: Why did life expectancy decline in 2017?

A: Mortality rates increased for 7 out of the 10 leading causes of death in the U.S., including a 5.9% increase in the flu/pneumonia death rate, a 4.2% increase in the accidental/unintentional injury death rate, and 3.7% in the suicide rate. Many of the accidental/unintentional deaths were from drug overdoses, which continued to increase in 2017.


Q: Isn’t this the third straight year that life expectancy declined?

A: Estimated life expectancy at birth in 2017 was 0.3 years lower than in 2014 and 0.1 years lower than in 2016. The 2016 life expectancy estimate was revised to 78.7 years, up from an estimated 78.6 years, which was reported a year ago. This means that the 2016 life expectancy estimate is the same as the 2015 estimate, which also was revised to 78.7 years, down from an estimated 78.8 years, originally reported two years ago. As a routine matter, for the highest degree of accuracy, NCHS blends Medicare data for people ages 66 and over with our vital statistics data to estimate life expectancy. However, the two data sets are released on different schedules. When Medicare data for a year aren’t available at the time we release our final mortality statistics, we use the most recent Medicare data available at the time. We later revise life expectancy estimates when updated Medicare data become available.


Q: How many deaths in 2017 were attributed to opioids?

A: In 2017, 47,600 drug overdose deaths mentioned involvement of any type of opioid, including heroin and illicit opioids, representing over two-thirds of all overdose deaths (68%).


Q: Why is the 70,237 number of overdose deaths smaller than what CDC has previously reported for 2017?

A: The 70,237 number is a final, official number of overdose deaths among U.S. residents for 2017 whereas the previously reported (and slightly higher) numbers were provisional estimates. In August of 2017, CDC began calculating monthly provisional data on counts of drug overdose deaths as a rapid response to this public health crisis, in order to provide a more accurate, closer to “real-time” look at what is happening both nationally and at the state level. These monthly totals are provisional counts, and they include all deaths occurring in the U.S. – which include deaths among non-residents (i.e., visitors here on business or leisure, students from abroad, etc). These counts also do not include deaths that are still under investigation. As a result, the monthly numbers are provisional or very preliminary, and the final 2017 number of 70,237 deaths is an official number that only include deaths among U.S. residents and account for any previously unresolved deaths that were under investigation.


Q: Does this mean that the 70,237 total does not include deaths to undocumented immigrants here in the U.S.?

A: We don’t get immigration status off the death certificates, so we wouldn’t know how many of the deaths were to undocumented immigrants.


Q: In comparing the 2017 numbers with 2016 and past years, is the crisis of drug overdose deaths growing or about the same?

A: From 2016 to 2017, the number of drug overdose deaths increased from 63,632 deaths to 70,237, a 10% increase, which is a smaller increase compared to the 21% increase from 2015 to 2016, when the number of drug overdose deaths increased from 52,404 deaths to 63,632 deaths. Over a longer period of time, from 1999 through 2017, the age-adjusted rate of drug overdose deaths increased on average by 10% per year from 1999 to 2006, by 3% per year from 2006 to 2014, and by 16% per year from 2014 to 2017. So the trend is continuing, although the increase in 2017 was not as large as in previous years.


Q: Are there any other trends of significance when looking at the types of drugs attributed to overdose deaths?

A: The rate of drug overdose deaths involving synthetic opioids other than methadone, which include drugs such as fentanyl, fentanyl analogs, and tramadol, increased 45% in one year, from 6.2 per 100,000 in 2016 to 9.0 per 100,000 in 2017. In 2017, 40%(?) of all drug overdose deaths mentioned involvement of a synthetic opioid other than methadone.


Q: Has fentanyl overtaken heroin as the major cause of overdose death?

A: The data brief on drug overdose deaths does not specifically address fentanyl. However the rate of drug overdose deaths involving synthetic opioids other than methadone, which includes fentanyl, increased 45% 2016 and 2017 whereas the overdose death rate from heroin did not change (4.9 deaths per 100,000).


Q: There is a lot of stark news in these three reports. Are there any positives to report?

A: The cancer mortality rate declined between 2016 and 2017, and although estimated life expectancy declined in 2017, life expectancy for people at age 65 actually increased. Also, regarding drug overdose deaths, the rate of increase in drug overdose deaths slowed between 2016 and 2017, although the increases that occurred were still very significant.

QuickStats: Homicide and Suicide† Death Rates for Persons Aged 15–19 Years — National Vital Statistics System, United States, 1999–201

June 8, 2018

In 1999, the homicide death rate for persons aged 15–19 years (10.4 per 100,000) was higher than the suicide rate (8.0). By 2010–2011, the homicide and suicide rates had converged.

After 2011, the suicide rate increased to 10.0 in 2016; the homicide rate declined through 2013 but then increased to 8.6 in 2016.

QuickStats: Age-Adjusted Suicide Rates by Race/Ethnicity — United States, 2015–2016

April 16, 2018

From 2015 to 2016, the age-adjusted suicide rate for the total U.S. population increased from 13.3 per 100,000 standard population to 13.5 (an increase of 1.5%).

The rate increased from 5.8 to 6.3 (8.6%) for non-Hispanic blacks and from 6.2 to 6.7 (8.1%) for Hispanics; it remained unchanged for non-Hispanic whites.

In both 2015 and 2016, the non-Hispanic white rate was nearly three times the non-Hispanic black rate and 2.5 times the rate for the Hispanic population.

Health, United States Spotlight Infographics – December 2017

December 13, 2017

A new Health, United States Spotlight Infographic from the National Center for Health Statistics is now available online. This infographic features data on teenage childbearing, tobacco use, suicide deaths and obesity.

Health, United States Spotlights are infographics of selected health data available in Health, United States, the annual report on the health of the nation sub

mitted by the Secretary of the Department of Health and Human Services to the President and Congress.

Content includes selected indicators on important public health issues from the report’s four subject areas: health status and determinants, utilization of health resources, health care resources, and health care expenditures and payers. Like the report, the Spotlights display the most current data available and, where possible, trends over a ten-year period.

For some indicators, a different set of data years or combined years of data may be shown, depending on survey cycles and design changes. Data sources are identified for each health indicator to enable further exploration and include data systems from both the National Center for Health Statistics and partnering government and private agencies. Changes over time and differences among groups are presented using standard statistical techniques used in Health, United States.

Each Spotlight displays approximately four health indicators allowing users to visualize and interpret complex information from different data systems and Health, United States subject areas. Multiple infographics will be released throughout the year to spotlight important and relevant health data from Health, United States.

QuickStats: Suicide Rates for Teens Aged 15–19 Years, by Sex — United States, 1975–2015

August 7, 2017

The suicide rate for males aged 15–19 years increased from 12.0 to 18.1 per 100,000 population from 1975 to 1990, declined to 10.8 by 2007, and then increased 31% to 14.2 by 2015.

The rate in 2015 for males was still lower than the peak rates in the mid- 1980s to mid-1990s.

Rates for females aged 15–19 were lower than for males aged 15–19 but followed a similar pattern during 1975–2007 (increasing from 2.9 to 3.7 from 1975 to 1990, followed by a decline from 1990 to 2007).

The rates for females then doubled from 2007 to 2015 (from 2.4 to 5.1). The rate in 2015 was the highest for females for the 1975–2015 period.
