Residential_Patterns_And_Marriage_Rule encompasses the spatial and social regulatory mechanisms that govern where married couples establish households and whom they may legitimately marry. This class includes post-marital residence patterns (patrilocality, matrilocality, neo-locality) that determine family proximity and support networks, as well as marriage rules that define acceptable and prohibited partners (endogamy, exogamy, incest taboo). These patterns and rules work together to structure social space, maintain group boundaries, prevent genetic problems, and facilitate alliance formation between social groups. The interplay between residential choices and marriage regulations reflects how societies balance competing needs for family support, social integration, genetic health, and group identity while managing potential conflicts and maintaining social cohesion across generations.
