Methods

Socio-economic and mortality analyses were conducted at a small area-level within each city.  The maps of Paris represent 987 Census Tracts or small areas.  Data from the 2007 Census was used to obtain the population size per Census Tract. 

As the population size per Census Tract was only available in Census data for 2007, the population figures for 2007 were multiplied by five to represent the total number of years included in the study period (2004 - 2009).  The INEQ-CITIES research of Paris is based on these figures. 

The table below shows the estimated population size per Census Tract by first, second (median) and third quartiles, based on 2007 figures from the National Institute of Statistics.
