This research focuses on understanding the changing aspects of slums in the light of rapid urbanisation. Rapid urbanisation in the developing world has led to a massive influx of rural population in urban centres, putting pressure on the urban infrastructure and services. This has led to the creation of widespread urban slums. However, today the nature of slums varies from that defined in modernisation theories. This research studies the varying nature of slums by firstly, investigating their changing employment trends (from informal to the formal sector) and secondly, by looking at their changing lifestyles (education patterns, use of technology and available government utilities). To this end, the research employs a qualitative approach by making use of semi- structured interviews to gauge an understanding of the chosen slum. The research found that the employment patterns in the chosen slum have changed over the generation and this change has also impacted their lifestyle; especially in terms of education, use of technology and availability of government utilities. Through this, the research aims to highlight the need to redefine urban slums in order to tackle the challenge of slums in the developing world. Supervisor:- Dr. Zulfiqar Ali
