Data from the slum poor were collected through observation and interviews, which were also used to determine the socio-economic status of the households. The determinants of socio-economic status included occupation, income, household size, durable goods possessed and the type of ownership of the settlement (temporary or transient settlers were worse off than long-term settlers). A small-scale qualitative survey was conducted through in-depth, open-ended interviews. During the interviews, the respondents were asked about their sources of income, health care, drinking water and sanitation, food safety and the condition of their waste disposal.
