About a billion US dollars and 36 million people ....
Seriously, Arca is actually the root of Nascar in the sense Nascar developed out of Arca over 50+ years back. Arca has stayed closer to it's roots, more oriented towards tradition and grass root, than popularity and money. You'll see drivers in ages from 16 to 75+ in Arca at times, and in the middle are guys trying to cut their teeth to make it into the bigger series.
Technically, Arca was very similar to Nascar in it's specs, rules and scoring up till the transition to COT in Nascar. Still they have similar traits and tendencies and experience from one to the other is commonly transferable from a driving standpoint. Prior to COT general differences between them was carburetor and spoiler height generally.
A decent article was written a while back on Arca that you may find interesting:
