A study of the English of British schoolchildren of South Asian extraction looks at ways of examining the relationship between their English and two ethnic processes, called "interactive" and "reactive". The way in which Network Analysis permits investigation of the interactive process is outlined, and the use of Identity Structure Analysis for examining the reactive process is considered. When the two methods of analysis are used together, they operationalize important components in Le Page's sociolinguistic hypothesis and riders and accommodate parameters fundamental to any neighborhood sociolinguistic survey.
