Also, in California: San Luis Obispo, Riverside, Sacramento, Fresno, Santa Barbara.
In Sweden, we also have administrative regions translated as counties, which are lead by someone I'd directly translate as "county chief" (as in "chief over this tribe") but they're anonymous bureaucrats a normal person wouldn't know about. (The common translation is the less exciting "governor".)
For some reason, the UK doesn't issue the title of "count", only "viscount". "Marquis" is linked etymologically to "marches", an old type of land allocation boundaries, but again not in practice.
When people outside of LA say "Los Angeles", they're almost always referring to the county. The city of LA is actually quite small.
For "San Diego", it's precisely the opposite - a giant portion of San Diego County is comprised of the city of San Diego, and they're almost always just referring to the city.
And for "San Francisco," the city and the county are basically the same entity and thus have the same borders.
