Alternative routes to Urban Density is funded by the International Institute for Environment and Development. The website is designed to address the challenges of urban density. It connects the viewer to IIED-funded research studies that address density issues. The studies are categorized city-wise and can be found on the 'Cities' page. Only cities with populations of more than five hundred thousand are listed. Cities will continue to be added to the list as research related to them are uploaded.

Non-IIED research studies have also been included as weblinks, providing access to the sites where they are located. These studies either directly address alternative methods to tackling the issue of urban density or have been undertaken to help understand Urban Geography, Urban Psychology, Urban Anthropology, Urban Health, Economics of Agglomeration and Sustainability. These studies will further aid research in to alternative methods.
