This thesis investigates use and attitudes of the Quechua language in Cusco, Peru. The author created and administered a 57-item questionnaire to 189 participants at two different institutions with large college-age populations to assess Quechua use across a number of family and social domains, and the data was aggregated and presented for these domains across the sociolinguistic factors, including gender, age, class, religion, parent language, and subject area of study. The factors that were the strongest predictors of Quechua use for the participants of the study were both parents reported as speaking Quechua as their L1, the participant reporting their ethnicity as quechua, the participant being lower class, and the participant being a non-Catholic Christian denomination. These factors were also more closely correlated with the participant being a student of tourism. The participants who had a closer connection with Quechua also reported slightly more positive attitudes about the Quechua language.
