Blacks in Ottawa and Gatineau
Below is a map of blacks in Ottawa and Gatineau, based on the 2016 census. The dark colours represent neighbourhoods that experienced the fastest growth between 2011 and 2016.

Median Household Income
The map is zoomed in to the Ottawa Census tracts. The dark colours represent the areas of highest median income in 2015, the most recent year for which Statistics Canada made income data available.
The city of Ottawa municipal boundaries are layered on top of the census tracts to provide a better sense of where the areas of interest are located.
Clicking inside the census tract boundaries produces a pop-up box with the median household income for 2005 and 2015, along with the percent change.
There are a few blank census tracts, which Statistics Canada says do not contain any data.
If you want to see other locations, simply zoom out, and then zoom in to the urban centre such as Vancouver, Toronto or Halifax.

Recent Immigrants – the 2016 Census
At first blush, it looks like there’s nothing on the map. So, you’ll have to zoom in. Areas like Vancouver, Calgary, Winnipeg, Toronto, Ottawa, and Halifax have the census tracts that contain the growth rates in recent immigrants between 2011 and 2016. Census tracts are located in communities with more than 100,000 people, and each census tract is a geographic area where between 2500 and 8000 people live. So, they’re quite small, as are the number of recent immigrants. Zooming in will take you to the colour-coded census tracts. The pop-up boxes contain numbers for 2011, 2016 and the percent difference. The rates in some areas are growing, remaining stagnant or shrinking. To avoid confusion, we have removed tracts in which zero recent immigrants were in 2011. Statistics Canada explains that “any change from 0 cannot be really measured as a % increase.” Although the agency does go on to explain that it’s important to “keep in mind that observed 0s should not be interpreted as true 0s – values could be rounded down or populations may not have been selected in the sample.”
Yellow represents negative growth. Tracts with the darker hues are in the positive.
