Marriage markets is a concept used in social sciences, particularly sociology, economics, and demography, to analyze the processes and structures through which individuals seek and form marital or long-term committed partnerships. This research concept investigates the dynamics of partner selection, considering factors such as individual characteristics, preferences, social networks, and broader socioeconomic and demographic structures that influence the availability and matching of potential partners within a defined population and spatial context. Its significance lies in providing a framework for understanding patterns of social stratification, assortative mating, demographic change, and the reproduction of social inequality through relationship formation processes.
