People who are undocumented workers in a specific city.

Why: undocumented workers are a hidden, hard-to-reach population — there is no reliable sampling frame, many avoid official contact for fear of legal consequences, and they may have language, mobility, and trust barriers. That makes identifying and obtaining honest survey responses much harder than the other groups, which typically have records or public access points (purchase records, employer rosters, or online forums).

If you need to survey them, common approaches include partnering with trusted community organizations, using snowball or respondent-driven sampling, venue-based outreach, bilingual staff, strong confidentiality protections, and careful ethical review.
