A cross-sectional study was conducted in 50 households in Padma Nagar and Shanti Nagar, the slums in Mumbai in March 2011. Purposive sampling was used to select the households. Pre-tested questionnaire was dispensed in a personal interview to the household head (19-49 years) regardless of gender, who were staying in the community for more than two years. The findings reveals that families with low income (less than INR 4000 per month) preferred to go to Brihanmumbai Municipal Corporation (BMC) hospitals where as families with more than INR 4000 income per month preferred to go to general practitioners. Respondents who had education up to secondary level preferred to go to the general practitioner where as those with education level higher than secondary preferred to go to BMC or private hospitals. From the issues that emerged from the study and recognizing the paramount importance of health in the well-being of the people, it is crucial that policy action be taken to improve health services for migrant populations who live in the unauthorized slums.
