Urbanisation is the defining feature of global population distribution. Until at least 2050, city growth will be concentrated in developing countries and most of that growth will come from migration from rural areas. Many poor, rural migrants will end up in the poorest neighbourhoods of these cities.
The objective of this study is to examine how the spread of the mass media, increased access to the internet and high levels of mobile phone use are changing the ways that poor people seek health-related information and advice. In order to pick up new patterns of behaviour with the potential to spread rapidly, we will study health information seeking behaviour in one relatively remote rural area, one rural area with good transport links to Dhaka and one slum in Dhaka.
