Context: <response>: Anthropologists don contribute to di debate by shifting di focus of research: One of di first wahala wey di researcher wey wan carry out empirical research for dis area go face na to identify an appropriate analytical tool. Di concept of boundaries dey useful here to show how identity dey work. Like Barth, for im approach to ethnicity, talk say make we focus on "di ethnic boundary wey define di group instead of di cultural stuff wey e dey enclose" (1969:15), social anthropologists like Cohen and Bray don shift di focus of analytical study from identity to di boundaries wey dem dey use for identification purposes. If identity na like virtual site wey dynamic processes and markers wey dem dey use for identification dey show, boundaries na di framework wey dis virtual site dey build on. Dem focus on how di idea of community belonging dey different for individual members and how individuals within di group dey see ethnic boundaries.
