Their city region labels are odd. The paper is behind a paywall, but it seems like San Diego & Ventura Co should be added to LA, and Tuscon should be added to Phoenix/Mesa. Maybe they're there already, but it feels like not from their choice of labels (not sure what high tech is in Riverside)

I believe they are using census areas, which are constructed by looking at population and then how they connect (e.g. do a reasonably % of people commute within this region, etc).

Ventura County, maybe, but Sam Diego is hours away from most of LA.

From Long beach you can get to San Diego as fast as San Fernando and Riverside.
