More than 1.65 million people live in the city of Montreal. Who are these Montrealers? Where do they live? And what do they share in common with their neighbours? Based on the results of the 2011 National Household Survey, Radio-Canada analyzed the characteristics (age, origin, marital status, cost of rent, …) of Montreal households located within an 800 meter radius of a metro station. We were able to show how different areas are their own mini-villages.

What makes this project innovative? What was its impact?

This project gave every metro stations in Montreal a socio-demographic “personality” using the census data. It visually described the remarkable diversity of the city’s population and illustrated the city’s social demography in a novel way. It is the first time this kind of analysis was done in Montreal.

Technologies used for this project:

QGIS was used to calculate an 800 meter buffer around every metro station and intersect the census tracts that fall inside these buffer. Then, in order to analyze the data, the pandas data analysis library for the Python programming language was used to calculate a weighted average of the data for the buffered tracts. The web charts were made with D3.js.
