A bit of a decline but "decimated" is too strong a word for a decline from 385,000 to 324,600, and much of that is due to smartphones and tablets (and single-board computers like the Raspberry Pi) that reduced the need for custom electronics. For example: in the 90s I worked for a company that made a custom handheld device. Now that product is an app.
