ISRM membership all-time record

The ISRM has now 6,783 individual members (an all-time record) and 140 corporate members, belonging to 49 National Groups. This represents an increase of 4% in the number of individual members since the last year. 46% of the members come from Europe, while Asia has been the fastest growing region in the last years.

The evolution of the total membership of the ISRM since its creation in 1962 is characterised by an initial fast growth—resulting from the impact of the 1st Congress and the creation of the National Groups, which catapulted the membership to over 4,000 in 1970—followed by a slower increase, with some oscillations. These are mainly connected with specific circumstances of some National Groups, the influence of the economic cycles, and the impulses given by the major meetings of the ISRM.

Europe, which at the beginning was by far the most important region, still accounts for 46% of the members. Asia, with a steady growth, is now the second most important region, with 26%, followed by North America, with 11%. Africa and Australasia have both 6%, and South America accounts for the remaining 4%. The number of National Groups had a steep increase to 36 in the years 1966–1979, and thereafter a slow growth, reaching now 49. The
ISRM has currently 140 corporate members, predominantly from Europe and Asia.
