Mortality – Stroke

Open in Report

This indicator reports the 2019-2023 five-year average rate of death due to cerebrovascular disease (stroke) per 100,000 population. Figures are reported as crude rates. Rates are resummarized for report areas from county level data, only where data is available. This indicator is relevant because stroke is a leading cause of death in the United States.

Note: Data are suppressed for counties with fewer than 20 deaths in the time frame.

Source Description

The Division of Vital Statistics is a branch of the Centers for Disease Control and Prevention (CDC) National Center for Health Statistics (NCHS) responsible for maintaining birth and death records for the nation. Data are compiled for the National Vital Statistics System (NVSS) through a joint effort between the NCHS and various state and local health agencies, who are responsible for registering vital events – births, deaths, marriages, divorces, and fetal deaths. NVSS statistics are released annually in various data warehouses, including CDC WONDER , VitalStats, and the Health Indicator Warehouse .

Methodology

County population figures and death statistics are acquired using CDC WONDER from the Underlying Cause of Death database and the Multiple Cause of Death database (for Opioid Overdose). Conditions were queried for years 2018-2022 based on a selection of codes from the International Classification of Diseases (ICD) 10th revision. The ICD-10 is the current global health information standard for mortality and morbidity statistics. The ICD has been maintained by the World Health Organization since its conception in 1948. A searchable, detailed list of current ICD-10 Codes (Version 2019) is available from the World Health Organization.

Mortality rates were acquired from the source as crude rate. To calculate mortality rates for unique service areas and aggregated county groupings, the following formula was used:

Mortality Rate = 100,000 * SUM (Count of Deaths) / SUM(Total Population or Population of Specific Age/Race/Ethnicity Group).

The specific codes used for reported mortality indicators are listed below (notice that motor vehicle crash, firearm, and poisoning are listed as part of the injury mechanism for all kinds of deaths and thus are not related with any specific codes).

  • Assault (homicide): U01-U02, X85-Y09, Y87.1
  • Cerebrovascular disease (stroke): I60-I69
  • Coronary (Ischaemic) heart disease:I20-I25
  • Chronic lower respiratory disease (lung disease): J40-J47
  • Heart disease: I00-I09, I11, I13, I20-I51
  • Intentional self-harm (suicide): U03, X60-X84, Y87.0
  • Malignant neoplasm (cancer): C00-C97
  • Unintentional injury (accident): V01-X59, Y85-Y86
  • Influenza and pneumonia: J09-J18
  • COVID-19: U07.1
  • Influenza-like Illness (ILI): J09-J18,U07.1
  • Opioid overdose: T40.0-T40.4
  • Drug overdose (all substances): X40-X44,X60-X64,X85,Y10-Y14
