THE International Stud Book Committee recently published their Statistical Information Booklet 2018, though the information contained is actually for 2017.

Approved stud books exist in four distinct regions, overseen by the European and African Stud Book Committee, North America and the Caribbean, South America (OSAF region), and finally the Asian Stud Book Committee and Oceania. A comprehensive list of foals born from 2015 to 2017, together with the numbers of thoroughbred stallions and mares active in 2017, is published here. It is a table that is fascinating when you start to look at the numbers closely.
