So far, linguistic differences have mostly been studied in the context of dialects, usually African-American Vernacular English -AAVE (Jørgensen et al., 2015), using message-level data which offered insight into syntactic (Stewart, 2014) or lexical markers (Blodgett et al., 2016).
not all users from a racial or ethnic group use these markers or, more generally, an associated dialect and usage is different across sociodemographic traits -use of the AAVE is correlated with lower income and education (Rickford, 1999).
