Apple has announced a huge expansion of its US operations, with intentions to create 20,000 new jobs around the country by 2023. Core to that effort is a huge $1 billion campus planned for North Austin, Texas.

Already, Apple employs 90,000 Americans across every single US state, with Austin representing its largest US workforce outside of its main “Spaceship” campus in Cupertino, California. That’s what makes it the obvious choice for expansion. CEO Tim Cook says the development will “significantly deepen [Apple’s] quarter-century partnership with the city and people of Austin.”

A press release adds a little detail about the operation: “the 133-acre campus will initially accommodate 5,000 additional employees, with the capacity to grow to 15,000, and is expected to make Apple the largest private employer in Austin.”

In addition to this flagship campus, new sites will also be established in Seattle, San Diego, and Culver City, creating over 1,000 jobs apiece – with smaller expansions taking place around the US, creating hundreds of new jobs in Pittsburgh, Boulder, and Portland.

It also plans to spend a whopping $10bn expanding its US data centers, which will run 100% on renewable energy.
