The days of crazy iPhone growth may be over, but the U.S. install base continues to tick upward — growing 14 percent relative to the December 2018 quarter.
According to new research published by Consumer Intelligence Research Partners, Apple’s total U.S. install base (the number of active iPhones being used) currently stands at 189 million units. With the U.S. population in the vicinity of 325.7 million people, that’s more than one iPhone for every two people in the country.
