Canada

I get the sentiment, but the term "colonial" is a bit condescending after 300+ years. It's like calling Turks or Magyars "nomads".

Were you thinking environmental pollution? That was my first thought, but then I remembered it could likely be due to the health care crisis there due to catastrophic understaffing of medical facilities. Recently some technicians for cancer screenings were even speaking out to say it definitely causing death from missed or delayed screenings. It's likely other health areas are similarly affected.

Incidentally, I find it gross they just put it beside homicide rate and don't explore anything else.

There have been a few mass casualty events at a few reserves across the province lately, might be skewing the stats upwards, hopefully it's just temporary.

Indigenous people are overrepresented among homicide victims in Canada: "The homicide rate for Indigenous people was over six times higher than for the non-Indigenous population (9.31 versus 1.46 homicides per 100,000 population)." ( source , which is 2023 data).

General Indigenous life expectancy is also lower—anywhere from 10 to 20 years difference at birth, depending on which information source and which subset of Indigenous people (Inuit lifespans are shortest overall). Here's some StatsCan data from 2011—I can't find anything more recent, although I'm sure it exists.

I haven't found any death statistics for Indigenous people in Saskatchewn specifically. They're ~17% of the population there, per Wikipedia, which is the highest % of any province I could find the information for quickly (more than double Alberta's, for instance), so Indigenous issues actually could be a significant contributor to Saskatchewan's statistical skew.
