I'll give you even odds that the number is within 4 orders of magnitude of correct. That is to say, in the year of 2025, there are/were fewer than 100,000 18 year olds, resident in the state of California, who have at least one child, and who made over $100,000 that year. If you prove me wrong I'll happily concede the point.
I guarantee you there are more than that just from trust funders/people working for their parents and religious enough to start families early.
Stop pasting LLM slop here.
