During the initial months of the Plan, National Spiritual Assemblies proceeded with relative ease to divide the territories under their jurisdiction into areas consisting of adjacent localities, called clusters, using criteria that were purely geographic and social and did not relate to the strength of local Bahá’í communities. Reports received at the World Centre indicate that there are now close to 17,000 clusters worldwide, excluding those countries where, for one reason or another, the operation of the Faith is restricted. The number of clusters per country varies widely—from India with its 1,580 to Singapore, which necessarily sees itself as one cluster. Some of the groupings are sparsely populated areas with only a few thousand inhabitants, while the boundaries of others encompass several million people. For the most part, large urban centers under the jurisdiction of one Local Spiritual Assembly have been designated single clusters, these in turn being divided into sectors, so as to facilitate planning and implementation.
