"The Jenks classification method is commonly used in thematic maps, especially choropleth maps, as one of several available classification methods. When making choropleth maps, the Jenks classification method can be advantageous because if there are clusters in the data values, it will identify them. See more The Jenks optimization method, also called the Jenks natural breaks classification method, is a data clustering method designed to determine the best arrangement of values into different classes. This is … See more Jenks’ goal in developing this method was to create a map that was absolutely accurate, in terms of the representation of data's spatial … See more • k-means clustering, a generalization for multivariate data (Jenks natural breaks optimization seems to be one dimensional k-means ).
