Key findings

Data from the National 

Vital Statistics System, 

Mortality

● For 2000–2016, the ageadjusted suicide rate increased

30%, from 10.4 to 13.5 per

100,000 population, increasing

on average by about 1% per

year from 2000 through 2006

and by 2% per year from 2006

through 2016.

● For females aged 10–74,

suicide rates in 2016 were

higher than in 2000.

● For males aged 15–74,

suicide rates in 2016 were

higher than in 2000.

● In 2016, for females,

suffocation accounted for a 

higher percentage of suicides 

among those under age 25, 

while poisoning accounted for a 

higher percentage among those 

aged 45 and over. 

● In 2016, firearms were the

most common means of suicide 

among males aged 15 and over.

In 2016, suicide was the 10th leading cause of death in the United States (1). 

Although the Healthy People 2020 target is to reduce suicide rates to 10.2 per 

100,000 by 2020 (2), suicide rates have steadily increased in recent years (3,4). 

This Data Brief uses the most recent data from the National Vital Statistics 

System (NVSS) to update trends in suicide mortality from 2000 through 2016 

and to describe differences by sex, age group, and means of suicide 

(e.g., suffocation, firearms, poisoning).

Keywords: National Vital Statistics System • death certificates • underlying 

cause of death • intentional self-harm

From 2000 through 2016, suicide rates increased for 

both males and females, with greater annual percentage 

increases occurring after 2006.

● From 2000 through 2016, the age-adjusted suicide rate increased 30%, from 10.4 per 

100,000 standard population to 13.5. The rate increased on average by about 1% per year 

from 2000 through 2006 and by 2% per year from 2006 through 2016 (Figure 1).

● For males, the rate increased 21%, from 17.7 in 2000 to 21.4 in 2016. The rate increased 

on average by about 2% per year from 2000 through 2002, did not statistically change from 

2002 through 2006, increased by about 2% per year from 2006 through 2010, and by about 

1% per year from 2010 through 2016.

● For females, the rate increased 50%, from 4.0 in 2000 to 6.0 in 2016. The rate increased on 

average by about 2% per year from 2000 through 2007 and by about 3% per year from 2007 

through 2016.

● The ratio of male-to-female suicide rates was 4.4 in 2000 and 3.6 in 2016. The narrowing in 

the ratio of male-to-female suicide rates reflects the accelerated increase in female suicide 

rates compared with male suicide rates beginning in 2007.

Suicide rates for females aged 10–74 were higher in 2016 than in 2000.

● Suicide rates for females were highest among those aged 45–64 in both 2000 

(6.2 per 100,000 females) and 2016 (9.9) (Figure 2).

● Although based on a small number of deaths, the suicide rate for females aged 10–14 

increased significantly, from 0.6 per 100,000 in 2000 to 1.7 in 2016.

● Suicide rates were significantly higher in 2016 compared with 2000 among females aged 

15–24 (5.4 and 3.0, respectively), 25–44 (7.6 and 5.4), 45–64 (9.9 and 6.2), and 65–74 

(6.2 and 4.0).

Suicide rates for males aged 15–74 were higher in 2016 than in 2000.

● Suicide rates for males were highest among those aged 75 and over in both 2000 (42.4 per 

100,000 males) and 2016 (39.2) (Figure 3).

● Suicide rates were significantly higher in 2016 compared with 2000 among males aged 

15–24 (20.5 and 17.1, respectively), 25–44 (26.2 and 21.3), 45–64 (29.1 and 21.3), and 

65–74 (25.9 and 22.7).

● The suicide rate in 2016 for males aged 75 and over (39.2) was significantly lower than the 

rate in 2000 (42.4).

In 2016, the means of suicide among females varied by age group.

● Among females aged 10–14, the most frequent means of suicide in 2016 was suffocation 

(119 of 171 deaths or 70%) (Figure 4).

● Nearly three-quarters of all suicides among females aged 15–24 involved either suffocation 

(509 of 1,148 deaths or 44%) or firearms (335 deaths or 29%).

● Among females aged 25–44, 32% (1,035 of 3,215 deaths) of suicides involved firearms, 

31% involved suffocation (1,004 deaths), and 28% involved poisoning (887 deaths).

● Poisoning was the most frequent means of suicide among females aged 45 and over, 

accounting for 40% of suicides among those aged 45–64 (1,720 of 4,253 deaths), 41% 

among those aged 65–74 (381 of 940 deaths), and 37% among those aged 75 and over 

(188 of 510 deaths).

● Firearms were the second most frequent means of suicide among females aged 45 and over, 

accounting for 32% of suicides among those aged 45–64 (1,361 of 4,253 deaths), 38% 

among those aged 65–74 (358 of 940 deaths), and 33% among those aged 75 and over 

(168 of 510 deaths).

In 2016, the means of suicide among males also varied by age group.

● In 2016, suffocation and firearms each accounted for about one-half (48%) of suicides 

among males aged 10–14 (128 and 126 of 265 deaths, respectively) (Figure 5).

● For males aged 15–24, about one-half of all suicides (2,348 of 4,575 deaths or 51%) 

involved firearms while another one-third (1,591 deaths or 35%) involved suffocation.

● For males aged 25 and over, the percentage of suicides involving firearms increased with 

age, from 48% of suicides among those aged 25–44 (5,362 of 11,181 deaths), to 55% among 

those aged 45–64 (6,579 of 11,943 deaths), to 74% among those aged 65–74 (2,574 of 3,463 

deaths), and to 81% among those aged 75 and over (2,656 of 3,291 deaths).

Summary

Since 2008, suicide has ranked as the 10th leading cause of death for all ages in the United States 

(1,5). In 2016, suicide became the second leading cause of death among those aged 10–34 and the 

fourth leading cause among those aged 35–54 (5).

This report highlights trends in suicide rates from 2000 through 2016. During this period, the 

average annual percentage increase in rates accelerated from approximately 1% per year from 

2000 through 2006 to about 2% per year from 2006 through 2016. The age-adjusted rate of 

suicide among females increased by 50% from 2000 through 2016, while the rate for males 

increased by 21%. Compared with rates in 2000, suicide rates in 2016 were higher for females 

in all age groups for those aged 10–74 and for males aged 15–74. Among the means of suicide 

(i.e., firearms, poisoning, suffocation, and other means), suffocation accounted for the highest 

percentage of suicides in 2016 among females under age 25, while poisoning accounted for 

the highest percentage among females aged 45 and over. Among females aged 25–44, the 

percentage of deaths from firearms, suffocation, and poisoning were similar (32%, 31%, and 28%, 

respectively). Suffocation and firearms each accounted for about one-half of all suicides among 

males aged 10–14, while firearms accounted for the highest percentage of suicides among males 

aged 15 and over.

Data sources and methods

Data were analyzed using the NVSS multiple cause-of-death mortality files from 2000 through 

2016 (6). Suicide deaths were identified using International Classification of Diseases, 10th 

Revision (ICD–10) underlying cause-of-death codes: U03, X60–84, and Y87.0 (7). Suicide 

deaths were categorized by means of suicide using ICD–10 underlying cause-of-death codes: 

firearms (X72–X74), suffocation (X70), poisoning (X60–X69), and other means (U03, X71, 

X75–X84, and Y87.0). Poisoning includes both drug and nondrug (e.g., toxic substances or 

gases) intoxications. Suffocation includes hanging, asphyxiation, and other mechanical and 

nonmechanical threats to oxygenation (e.g., trapped in low oxygen environment). Other means 

include such mechanisms as cutting and piercing; falls and jumping; burns from fire, hot 

substances, and hot liquids; and transportation. Age-adjusted death rates were calculated using 

the direct method and the 2000 U.S. standard population (8). The small number of suicides during 

2000–2016 for persons aged 5–9 (88 deaths) were included in the total numbers and age-adjusted 

rates but not in age-specific numbers or rates. Trends in age-adjusted death rates were evaluated 

using the Joinpoint Regression Program (9). The default setting of a maximum of three joinpoints 

was used to assess trends from 2000 through 2016. Male-to-female rate ratios were calculated as 

the male age-adjusted rate divided by the female age-adjusted rate. Pairwise comparisons of rates 

in Figures 2 and 3 were conducted using Student’s t test statistic.
