According to Statistics Canada, 88.1% of Canadians had a smartphone in 2021. 33/38 is about 86%, so in the same ballpark. Maybe a few more percentage points have non-smart cellphones (though many flip phones these days run Android so they probably get counted as smart), but I think there are more cellphoneless people than many folks in the tech industry might assume. https://www150.statcan.gc.ca/t1/tbl1/en/tv.action?pid=2210011501 https://www150.statcan.gc.ca/t1/tbl1/en/tv.action?pid=221001...

  Seems like a reasonable avenue.. but it must be skewed by multiple devices (work+personal phone, phone+tablet+laptop each with a SIM - them being the same account isn't particularly relevant), and presumably it was `anonymize(SELECT * FROM active_sims)`.. including visitors and anyone else on the networks, which would also include children.
