Granted - this isn’t really innumeracy, but still…
One of the charter schools in my area has several campuses. They have a “COVID-19 Dashboard” where they show the numbers of cases for the different campuses. The dashboard has 4 columns: Campus, Active Cases, Percent of Campus Population, and Rate per 100 Individuals.
Not surprisingly - the 3rd and 4th columns have the exact same numbers in them.
Maybe not in emerald - I can’t see anywhere where the way they calculated the number is described - but “more than 90% less” is a ridiculously convoluted way of presenting any information. I’m not entirely sure what it even means.
It probably means that the average wealth for Black women is less than 10% of the average wealth for White men in America, but more than 90% less is a more compelling phrase than the other because people are used to discount language from retail, half off, 75% off, etc, so the wording leans into that understanding, imo. I’m “more” interested in their definition of American/America (only interested enough to comment, not actually click and read, I’m definitely doing the “didn’t even read the article, just the title” commenting here). It’s unlikely to be all of the americas, and most likely to be U.S. but it’s also ambiguous.
