The number of municipalities involved in IMC can vary widely, from only two neighbouring municipalities to several tens of municipalities. For instance, it is not uncommon that entire micro-regions get involved in IMC to promote their tourism potential or protect the environment. Larger municipalities with greater capacities and resources often provide services to the smaller neighbouring ones.
The larger the number of municipalities involved in IMC, the more complex the cooperation. This is the reason that IMC is often initiated by a few municipalities and over time, additional neighbouring municipalities join the partnership (or drop out of it). In Spain, for instance, the average number of municipalities involved in mancomunidades is eight, and 50 percent of them have six or fewer members, with the largest having 94 member municipalities.
