IHME, Global Burden of Disease – Global Burden of Disease Study

Dataset showing the number of countries with primary data on the prevalence of mental illnesses. These were found after a systematic review, grey literature search and expert consultation, to identify studies with data on the prevalence of each mental illness.

'The GBD inclusion criteria stipulated that: (1) the diagnostic criteria must be from 1980 onward; (2) "caseness" must be based on clinical threshold as established by the DSM, ICD, Chinese Classification of Mental Disorders (CCMD), or diagnosed by a clinician using established tools; (3) sufficient information must be provided on study method and sample characteristics to assess the quality of the study; and (4) study samples must be representative of the general population (i.e., case studies, veterans, or refugee samples were excluded). No limitation was set on the language of publication.'

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
