A number of large tech companies have released 2015 data outlining how diverse their workforces are. Last week, it was Facebook. The social networking company increased how many black employees it added in the United States from 45 to 81 over the past year -- out of about 5,500 total employees. Other companies, as detailed in this nice Wall Street Journal graphic, weren't much different: mostly white and mostly male.

Being a bit obsessed with demographics at the county level, we were curious which counties in the United States most closely matched the demographics of the companies' technology and executive jobs. (OK, we were also inspired by this tweet.) So we looked at the 2014 data for each county and compared it to the 2015 data for Facebook, Google and Microsoft (and the 2014 data for Apple, the most recent available).

If these companies were a county, they'd be in Alaska -- at the western edge of the Aleutian islands.

Well, that's depending on how you slice it. The county that's most like the companies' gender make-up is Concho County, Texas, where men outnumber women by more than two-to-one. (Concho County is sheep country, near the center of the state.) The counties most like the companies' tech staff are in remote parts of Alaska, where there is a higher ratio of Asian-American to white residents.

Compared to the executive staff, though, it's slightly different. The composition of the executive staffs of Facebook, Google and Microsoft overall is like Forest County, Pa. -- just on the edge of the Allegheny National Forest near Erie. Looking only at racial demographics, they're more like Snohomish County, Wash., outside of Seattle. Apple is nearly the same, looking like adjacent King County -- which happens to be the home of Microsoft.

In other words, Microsoft's executive staffers look pretty much like the community where they live. Their tech staffers look more like the residents of the Aleutians.

Make of that what you will.
