This data visualization uses a choropleth map to highlight changes in data for each Boston neighborhood between 1990 and 2010 to determine a baseline for gentrification, which will enable further analysis helping to identify factors contributing to this change in city demographics. Users can search by percent poverty, higher education status, and percent income spent on rent.


The data used comes from the 1990 and 2000 US Census and 2008-2012 American Community Survey 5-year estimates for census tracts in Suffolk, Middlesex, and Norfolk counties in Massachusetts. We accessed the data using Social Explorer. We normalized the 1990 and 2000 Census data to 2010 census tract boundaries using aerial weights interpolation methods provided by the Longitudinal Tract Database. The 2008-2012 data uses the 2010 census tract boundaries. All dollar values are adjusted to 2013 constant dollars.
