Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for generating a diversity index. A diversity index system determines distribution values indicating a distribution of a set of users among demographic groups defined by two or more diversity dimensions. The diversity index system generates a distribution vector based on the distribution values. The diversity index system determines, based on the distribution vector and a similarity matrix, a set of diversity index values forming a diversity index vector. The similarity index includes a set of similarity scores for the demographic groups. The diversity index system determines a diversity index score for the set of users based on the diversity index vector and the distribution vector. The diversity index score indicates a level of diversity amongst the users from the set of users.
