In the map and horizontal bar chart, the data is presented in five classes created using the quantile classification method. Each class contains 20% of countries, which is easy to interpret. The quintile intervals are labeled sequentially from Quintile 1, also called the bottom quintile which includes the lowest fifth (0 to 20%) of data points to Quintile 5 (or top quintile), which includes the top fifth (80% to 100%) of data points.
Measure: Death, Disability-Adjusted Life Years (DALYs), Years Lived with Disability (YLDs), and Years of Life Lost (YLLs) due to premature death.
Unit of measurement: For mortality measures: deaths per 100,000 population. For measures of burden of disease: years per 100,000 population.
Topic: Mortality and burden of disease.
Rationale: Measuring how many people die each year and why they died is one of the most important means – along with gauging how diseases and injuries are affecting people – for assessing the effectiveness of a country’s health system. Statistics of causes of death and disability help inform public health policy and planning.
Cardiovascular disease death rate: Number of deaths due to cardiovascular diseases in a year, divided by the population and multiplied by 100 000.
DALY rate: Number of DALYs due to cardiovascular diseases in a year, divided by the population and multiplied by 100 000.
YLD rate: Number of YLD due to cardiovascular diseases in a year, divided by the population and multiplied by 100 000.
YLL rate: Number of YLL due to cardiovascular diseases in a year, divided by the population and multiplied by 100 000.
Cardiovascular disease categories and ICD-10 codes:
The full list of cause categories and corresponding ICD-10 codes is detailed in the technical document WHO methods and data sources for country-level causes of death 2000-2019, Annex A, page 62.
The burden of disease cause list is organized in a hierarchical fashion with four levels of aggregation. The cause list is mutually exclusive and collectively exhaustive at every level of aggregation; causes not individually specified are captured in residual categories.
Disaggregation: Age, Sex, Country, and Year.
The categories "All-ages", and "Age-standardized" from the dimension Age, combined with the metric "Rate" have the following meaning:
- All-ages indicate that the rate is crude (without removing the effect of age distribution across population groups).
- Age-standardized indicates that the rate refers to all ages but the rate was age-standardized by the direct method using the WHO world standard population.
Method of estimation: Mortality and burden of disease measures by cause, age, sex, year, and location (countries, the region of the Americas, and subregions) were extracted from the World Health Organization (WHO) Global Health Estimates 2000-2019 (GHE). These data represent the best and latest estimates of the WHO which have been computed using standard categories, definitions, and methods to ensure cross-country comparability, and may not be the same as official national estimates.
Data sources and methods for estimating causes of deaths and burden of diseases are described in the following documents:
Method of estimation of the regional and subregional aggregates: Calculated by aggregating the country values (both numerator and the population) using population estimates from the World Population Prospects 2019, produced by the UN Population Division, as denominators.
Preferred data sources: Civil Registration and Vital Statistics (CRVS) systems with complete coverage and medical certification of cause of death.
