When we talk about subpopulations, we refer to smaller groups within a larger population that share common characteristics or traits. However, there are several synonyms that can be used interchangeably with the term subpopulations to provide more variety in writing. These synonyms include groups, demographics, segments, subsets, clusters, communities, cohorts, and factions. Each of these words can help to convey a specific context or nuance when discussing a particular group of people or organisms. Whether you are a researcher, a journalist, or a writer, it is important to have a diverse vocabulary to accurately describe different types of subpopulations.
