Is Government Inflation Reporting Accurate?

Who ya gonna believe: official CPI figures or your lyin' eyes?

Great news! We’ve brought inflation back under control and stuff is now only costing you 2.4 percent more than it did last year!

That’s more or less the message we’ve been hearing from governments over the past couple of years. And in fact, the official Statistics Canada consumer price index (CPI) numbers do show us that the “all-items” index in 2024 was only 2.4 percent higher than in 2023. Fantastic.

So why doesn’t it feel fantastic?

Well statistics are funny that way. When you’ve got lots of numbers, there are all kinds of ways to dress ‘em up before presenting them as an index (or chart). And there really is no one combination of adjustments and corrections that’s definitively “right”. So I’m sure Statistics Canada isn’t trying to misrepresent things.

But I’m also curious to test whether the CPI is truly representative of Canadians’ real financial experiences. My first attempt to create my own alternative “consumer price index”, involved Statistics Canada’s “Detailed household final consumption expenditure”. That table contains actual dollar figures for nation-wide spending on a wide range of consumer items. To represent the costs Canadian’s face when shopping for basics, I selected these nine categories:

• Food and non-alcoholic beverages

• Clothing and footwear

• Housing, water, electricity, gas and other fuels

• Major household appliances

• Pharmaceutical products and other medical products (except cannabis)

• Transport

• Communications

• University education

• Property insurance

I then took the fourth quarter (Q4) numbers for each of those categories for all the years between 2013 and 2024 and divided them by the total population of the country for each year. That gave me an accurate picture of per capita spending on core cost-of-living items.

Overall, living and breathing through Q4 2013 would have cost the average Canadian $4,356.38 (or $17,425.52 for a full year). Spending for those same categories in Q4 2024, however, cost us $6,266.48 - a 43.85 percent increase.

By contrast, the official CPI over those years rose only 31.03 percent. That’s quite the difference. Here’s how the year-over-year changes in CPI inflation vs actual spending inflation compare:

As you can see, with the exception of 2020 (when COVID left us with nothing to buy), the official inflation number was consistently and significantly lower than actual spending. And, in the case of 2021, it was more than double.
