  • Night Lights

    Measurements of economic growth often fall short for developing countries, particularly in sub-Saharan Africa, and are rarely calculated at all for cities throughout the world. In a new working paper, three Brown University economists suggest a way to improve GDP estimates for such areas by using images of nighttime lights as seen from outer space.

  • LTDB - Following Neighborhoods over Time

    The Longitudinal Tract Data Base estimates population characteristics for constant small areas from 1970 through 2010, based on census tract boundaries in 2010.  These data can also be viewed in a web-based map or downloaded.

  • Urban Transformation in South Africa

    With support from the National Science Foundation (grant #0527667) in the US, Patrick Heller (the principal investigator) and other researchers at Brown University as well as in South Africa have been examining urban transformation in South African cities since the end of apartheid. This research uses Geographic Information Systems (GIS) data to map spatial changes in infrastructure and demographics. 

  • Rio/São Paulo Project

    The Rio/São Paulo Project is one component of research on Brazil being conducted by Brown social scientists. It is a study of spatial inequalities in two major Brazilian cities in 2000 and 2010, led by sociologist John Logan in collaboration with colleagues in Brazil and Paris.

    Data sets at the scale of Setores Censitarios and Areas de Ponderacao will be available soon for download from this site, along with shape files and a web-based GIS map system to visualize these data.


  • Hurricane Katrina Project

    The Hurricane Katrina Project examines the impacts of hurricanes on the Gulf Coast.  It began in response to the specific case of New Orleans’ flooding in 2005 and efforts to understand who was affected and what neighborhoods were able to rebuild.  Since then it has evolved into a broader study of the Gulf Coast region in the decades since 1950.  Major participants in this project have include John Logan, Zengwang Xu (now at the University of Wisconsin-Milwaukee), and Sukriti Issar (now at Sciences Po in Paris).
