The fourth revision of Bertillon’s original classification of causes of death introduced some important developments. A copy of ICD-4 can be found at the WHO website. The publication is written in French and is 223 pages. Dr Jacques Bertillon headed previous revisions but had passed away in 1922. There is a further reference to the fourth revision of the international classification of the causes of death in this article at the WHO website. The conference for the fourth revision was held in 1929.

There were two important developments in the fourth revision

(1) The classification now included causes of morbidity as well as mortality

‘Nomenclatures International Des Maladies (Causes De Décès, Causes D’Incapacite De Travail)’

which via Google Translate is

‘International Nomenclature of Diseases (Causes of death, Causes of work disability)’

(2) The revision was a combined undertaking by the International Institute of Statistics and the Health Organisation of the League of Nations. The newly formed League of Nations followed the Paris Peace Conference and focused on establishing peace and stability after the events of World War 1.

The publication lists 200 causes of death and morbidity.
