I know that reality often has little place in our political debates, but is there any way we can the New York Times and other news outlets to stop saying that the U.S. economy is the world's largest? It happens not to be true.

According to the I.M.F., using purchasing power parity measures, which most economists view as the best measure, China passed the United States in 2015 and is now more than 25 percent larger. Maybe reporters and editors get a kick out of saying that the U.S. is the world's largest economy, but since it happens not to be true, it would be good if they stopped saying it.
