Clustering (demographics): In demographics, clustering is the gathering of various populations based on ethnicity, economics, or religion. In countries that hold equality important, clustering occurs between groups because of polarizing factors such as religion, wealth or ethnocentrism.

Key clustering: Key or hash function should avoid clustering, the mapping of two or more keys to consecutive slots. Such clustering may cause the lookup cost to skyrocket, even if the load factor is low and collisions are infrequent. (Social) [70%] 2023-05-27 [Key management]
Clustering coefficient: In graph theory, a clustering coefficient is a measure of the degree to which nodes in a graph tend to cluster together.
