This study focuses on one of the factors that affects purchasing power, namely spending, and uses the K-means algorithm to analyze it. This algorithm helps to group data into clusters, which enables a better understanding of purchasing power based on the expenditure levels of people in districts and cities in West Java. The research was conducted using the CRISP-DM method with the K-means algorithm, which is applied to perform data mining on expenditure level data of district and city communities in West Java, listed in West Java Open Data. The data consists of 320 regions including cities and regencies in West Java Province, from 2010 to 2021, with provincial codes, regency codes, and cities.
