Politico quotes Donald Trump :
Just this past week, Trump reveled in a mental list he has been keeping of how many tests the U.S. has conducted, approaching 14 million, in comparison with other countries — Germany at 3 million, Italy at 3 million. That list, like so many others, is designed to ensure American is ranked No. 1. Trump deflected when a reporter asked how America’s testing compared to other countries on a per capita basis, a measure by which the U.S. lags behind several countries.
“You know, when you say ‘per capita,’ there’s many per capitas,” he said. “It’s like, per capita relative to what? But you can look at just about any category, and we’re really at the top, meaning positive on a per capita basis, too.”
It has been a few decades since I was at school. Are there many, or even multiple, per capitas?
