Introduction

Introduction

Suicide was the 11th leading cause of death in 2002.

Suicide rates have declined since 1950.

YearRate*Rank, cause of death**

200210.9 11th

1990 12.5 8th

1950 13.2 12th

* Age-adjusted, per 100,000 resident population.

** Ranking is based on number of deaths (as opposed to rates).


Methods

Methods

  • Mortality data from the National Vital Statistics System 1950-2002

  • Resident populations from the US Census Bureau used to calculate rates

  • ICD external cause codes for suicide:

    ICD-10 1999-02*U03,X60-X84,Y87.0

    ICD-9 1979-98E950-E959

    ICD-81968-78E950-E959

    ICD-71958-67E963, E970-E979

    ICD-61949-57E963, E970-E979

  • For data years 1995-2001, the Dept. of Agriculture urban-rural continuum codes were used to differentiate between five levels of urbanization. Detail available with handouts.

  • The average annual percent changes in suicide rates were estimated using negative binomial regression models.

  • Where specified, rates were age-adjusted to the year 2000 standard population.


Suicide trends 1950 2002

The ICD-9 and ICD-10 external cause of injury mortality matrices were used to classify the mechanism of suicide.

The comparability ratio (CR) for suicide between ICD-9 and ICD-10 was 1.00.

The three leading mechanisms of suicide, firearm, poisoning and suffocation also had CR’s of 1.00.


Highlights age and mechanism

Highlights: Age and Mechanism

  • From 1950 to 1980, suicide rates among those ages 15-34 years increased and rates among those 45 and older decreased. Since 1980, the patterns have been less defined.

  • Between 1994-95 and 2001-02 suicide rates by single year of age decreased among those younger than 38 years; increased among people 39-59 years and decreased among people 60 years and older

  • Firearms are the leading suicide mechanism followed by poisoning and suffocation.


Suicide trends 1950 2002

Highlights: 1995-2002

  • Firearm suicide rates declined among all age and sex groups. Among persons 65 years and older, the 3 leading mechanism-specific suicide rates also declined.

  • Among 10-14 and 15-19 year olds, overall suicide rates decreased. With the decline in suicide by firearm, suicide by suffocation (hanging) became the leading mechanism for males and females 10-14 years and for females 15-19 years.


Highlights urbanization

Highlights: Urbanization

  • Suicide rates are higher in counties that are less populated and lower in counties that are more populated.

  • In 2001, as the level of urbanization decreases the percent of suicides involving firearms increases. A similar pattern was seen in1995.
