Building on our previous efforts to study the relationship between income and COVID-19 in North American cities, the GeoSDH research group has developed a new map of these measures in Montreal.

The left side of the map (blue) shows median household income by Montreal borough using data from the 2016 census. The right side (red) shows the COVID-19 infection rate per 100,000 people by borough, based on data from October, 2020. As with our scatterplots of other North American cities, there is a negative trend, such that lower income neighbourhoods tend to have higher rates of COVID-19 cases.

Interestingly, this map also shows that both income and COVID-19 rates vary geographically in Montreal east to west. If you slide the toggle back and forth, you will see that neighbourhoods in the west of the island tend to have low rates of COVID-19 and high median income whereas neighbourhoods in the east tend to have high rates of COVID-19 and low median income.

This is a clear example of the social gradient of health and also shows that where you live and your health are often closely linked. Explore the map to look for trends, and view the numbers in each neighbourhood by clicking on individual boroughs. See more like this in our ArcGIS StoryMap.
