Many of Apple’s hardware products are built overseas, but that’s only part of the story. The New York Times takes a look at Apple’s impact on jobs in the United States, focusing special attention on Austin, Texas where Apple fills a seven-building complex of tech support specialists, microchip engineers, supply chain managers, and people who work in Apple Music, the App Store, and Maps:

Apple’s overall contribution to the American economy is significant. Beyond the 80,000 people it directly employs in the United States, it says 69 supplier facilities in 33 states manufacture parts that go into its products. Hundreds of thousands of software developers also write apps for iPhones and iPads.

Technical support call center employees earn around $30,000 per year, but the average in Austin is around $77,000. Asked by The New York Times whether it planned to expand operations in Austin, Apple said:

“Apple has created over two million jobs in the United States since the introduction of the iPhone nine years ago, including explosive growth in iOS developers, thousands of new supplier and manufacturing partners, and a 400 percent increase in our employee teams,” the company said in a statement. “We made the unique decision to keep and expand our contact centers for customers in the Americas in the United States, and Austin is home to many of those employees. We plan to continue to invest and grow across the U.S.”

Apple’s Austin offices have grown a lot over time, but don’t get much attention despite their size. The New York Times’ article is an interesting overview of the breadth of Apple’s impact on the US economy and peek inside Apple’s Texas offices.
