Not sure how long this has been live, but this morning fellow cancensus developer Dmitry flagged a new StatCan feature. Interactive thematic web maps. Essentially it enables users to choose from the a selection of 2016 census variables and map them. You can zoom and pan around, and select the aggregation levels to display the data at down to census tracts. And there is a option to download single variables as CSV.

Why overly focussing on medians is dangerous.

I want do a short post to gently remind people of pitfalls when overly relying on medians for understanding complex issues. Medians are useful because they take a complex distribution and break it down into a single, simple to understand number.

The dire home affordability in Vancouver weights heavily on everyone’s mind and it seems like we reflexively try to explain everything that is happening, or that we think is happening, though that lens. After we seem to have thankfully left the meme that millennials are fleeing Vancouver behind, an article claiming that Vancouver’s middle-aged population is leaving keeps popping up in my Twitter feed. The data point in the story is that between 2006 to 2016 the City of Vancouver saw a 13% drop in the number of people in the 40 to 44 year age group.
