Just over 20 years ago, the Ontario government created a new City of Hamilton by amalgamating what had previously been the city with surrounding towns. At the time it was highly controversial. One town, Dundas, held a plebiscite (an unofficial vote) on the issue. About half the electorate voted - far more than typically turn out f…

Failure to sample can be dangerous to your health
Harry Shannon
Background: Municipalities in Ontario held elections last week. A couple of days before, the Hamilton Spectator published a letter complaining that an opinion poll reporting on the race for Mayor was useless. I responded and the letter was in the print edition a few days later. Below is the letter I sent; there were some minor edi…
Should we raise the retirement age? No
Should we raise the retirement age? That’s what an opinion article in the Hamilton Spectator last week proposed.
The author argued his case using data on life expectancy (LE). He noted that back in 1965, when Canada Pension Plan began, LE for men was 66.8, for women 73. He then stated that, since the pension age was 65, men only got CPP for a…
An end to polls?
Harry Shannon
I was looking for information on electric vehicles (EVs). Through our local library, I saw the May 2022 edition of BBC Top Gear magazine. The front page promised ‘THE ELECTRIC AWARDS.’
The table of contents included ‘Reader’s Choice’ and went on: ‘Did you choose your favourite in the poll to end all polls. TG reader…
How to get rooked
Harry Shannon
If you grew up in the UK before 1971, you had to learn how to cope with your money, which was divided into pounds, shillings, and pence (pennies). The abbreviation is Lsd (or £sd), after the Latin names.
I hadn’t realised before, but according to Wikipedia this was a system once used across Western Europe. There were 12 penc…
UK’s Daily Mail misleads on COVID-19 vaccines
Harry Shannon
What is it about people who write or speak for a living? You often hear them proudly announce that they can’t do math. Which really means they are admitting they’re not properly educated.
It has consequences. If journalists are innumerate, they can’t do their job well. Anyone with an agenda can easily mislead them, and in…
Dear Albertans
Harry Shannon
I sent the article below to the Calgary Herald as a possible contribution to their Opinion page. I haven’t even had an acknowledgement.
Some context: I wrote this after hearing the Alberta Premier Jason Kenney on the news. Kenney and his government have tried to keep the province’s economy open during the COVID-19 pandemic.…
Emerald is Not a Gem
Harry Shannon
This morning I got an email from Emerald Publishing, publishers of hundreds of academic journals. The email began:
“In August 2020, we commissioned a global survey to gather views on change within the academic sector. The survey was sent to a random selection of 172,033 academics, librarians and students within …
How big a wealth gap is too much?
Harry Shannon
I wrote this letter to Prime Minister Justin Trudeau, and several members of his cabinet:
There is a lot of talk about a wealth tax and about billionaires, but it’s hard for most people to understand just how much money the ultra-wealthy have. Even as a statistician, I have trouble getting to grips with the numbers. So I wan…
Who is most at risk for COVID-19?
Harry Shannon
Data just released show that “Black people and other people of colour make up 83 per cent of reported COVID-19 cases while only making up half of Toronto's population.”
Quick now – how many times more likely are these racialized people to get COVID-19 than the rest of the Toronto population, i.e., white people? 1 ½ ti…
