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 pen portrait of the movement in each country and key contact information. 

The latest information is in The Brethren Movement Worldwide: Key information, fifth edition (2019) edited by Ken and Jeanette Newton (Australia) for the IBCM7 conference in Italy in June 2019.
