Fact check: Trump claims U.S. excels on testing, but omits key detail
Raw data versus per capita
But the huge difference in population adds an important piece of context to those figures.
The U.S. population is 328,239,523, according to the U.S. Census Bureau. South Korea’s is 51.8 million.
That means South Korea has tested roughly one in every 144 of its residents. In the U.S., the per capita testing rate is closer to one in every 900 residents.

What and Why
Testing is a crucial part of any public health response, and sharing test data is essential to understanding this outbreak. The CDC is currently not publishing complete testing data, so we’re doing our best to collect it from each state and provide it to the public. The information is patchy and inconsistent, so we’re being transparent about what we find and how we handle it—the spreadsheet includes our live comments about changing data and how we’re working with incomplete information.

Where the U.S. Stands Now on Coronavirus Testing
This week, the number of coronavirus tests in the United States surpassed those in South Korea and Italy — two countries that had been testing more aggressively.
But the United States, which has the most known coronavirus cases in the world, continues to lag in tests per capita, according to an analysis of estimates from the COVID Tracking Project. Both South Korea and Italy have much smaller populations than the U.S.
The United States cannot even test everyone who is sick because of a shortage of testing kits and personal protective equipment for health care workers.
