Well they made two math mistakes.
1. Decimal point 0.4 instead of 0.04.
0.4% of the U.S. pop in 1990 would be about 1.1 million PEOPLE.
2. They conflated households with people. Which is it: 1.1 million people or 1.1 million households.
In 1990, there were 2.6 persons/household average.
So! Are we talking about 1.1 million ppl, or 2.9 million ppl?
Hard to tell per the article.
1.1 million Households would be 1.1% of the U.S. pop in 1990, given 2.6 persons per household......
What a dumb article. The media is full of dumb people who think they are geniuses. (I intend no disparagement of the thread's author by that comment, BTW.)
When we carefully exam the 1990 tables, it appears that the aggregated U.S. data is saying that 1.1% of American residences did not have tie-ins to public sewers, septic tanks, or cesspools. Using a multiplier of 2.6, we do wind up with 2.9 million Americans without regular indoor toilets in 1990.
That figure was 1.16 percent of the American population--not 0.4% and certainly not 0.04%.
Math is not a required subject in journalism school.....................and neither is English grammar, apparently....................
