Data were collected through face to face interviews using respondent driven sampling (Labor Trafficking Main Data, n=826 and Specific Trafficking Incident Data, n=826). There were sixteen interview sites spread across San Diego county. All interviews were conducted with at least two interviewers present. The study used a total of seven bilingual interviewers who conducted 826 valid interviews. Each subject was paid thirty dollars for participating in the interview, and given three referral coupons worth ten dollars each. The Respondent Driven Sampling (RDS) began with an initial set of "seeds" recruited from the target population through a combination of recruiting strangers at day labor sites and existing community contacts within the social networks of Center for Social Advocacy (CSA) outreach workers. To be eligible for participation in the study, one had to be unauthorized in the United States and be working (or have worked within) the past 3 months. Other than the seeds, all subsequent referrals had to call the project phone number to schedule interviews with their coupon numbers.
