At the IBCM3 conference, it was agreed to improve information about the Brethren movement in different countries. In particular, for each IBCM conference, the organisers try to bring together information from as many countries in the world as possible, to provide a overview of the movement in each country and key contact information. 

The latest information is in The Brethren Movement Worldwide: Key information, sixth edition (2022) edited by Neil Summerton (UK) for the IBCM8 conference held in Kuala Lumpur, Malaysia, in June 2023.
