qualitative-analysis - Question and answers

I'm a junior researcher in sociology focusing on urban politics, and for this project, I need to understand the nuanced ways social class affects voter turnout and activism. I've reviewed existing literature that often uses surveys to quantify participation rates, but I suspect interviews might reveal underlying social barriers. My constraints include a limited sample size of about 200 participants and a tight timeline of 6 months. I've already drafted a survey questionnaire, but colleagues suggested interviews could add depth. How should I balance generalizability with detailed insights?
