This replication package provides the data and code to reproduce the results reported in the published paper: "Do doctors contribute to socioeconomic inequalities in health care provision? An audit experiment in Tunisia". The data were collected through structured questionnaires completed by Standardised Patients (SPs) after visits to primary care providers in public facilities and private clinics in urban Tunisia. The dataset includes 260 SP visits, portraying either a middle-class or a lower socioeconomic (poor) patient profile. The questionnaires captured consultation time and duration, questions asked, physical examinations performed, communication and advice provided, treatment plans (including drugs that were prescribed or given free-of-charge), and visit costs. The study also included a GP survey and clinical vignettes to test the knowledge of GPs.
