Ok? But that's in reference to ANAKIN, the strongest Force user ever. They would have found HIM if he was born in the Republic. My impression is that other, not-as-strong Force users are likely slipping through the cracks. And that still leaves likely hundreds if not thousands of non-Repbulic planets and the probably trillions of "undocumented" sentient beings that populate those planets.
In the Clone Wars series, they have records of force-sensitive children born within the republic and allow them to get to a certain age before bringing them to the temple. There's a couple of episodes where they show them retrieving them, and even one where they have to protect them from a bounty hunter who has acquired their names and locations.
It's also shown the other way, however, where places like Dathomir (where Maul came from) have untapped force users, even strong ones (his brother is an example) that are not found. The way it's been presented in the past is that force powers are difficult to master, which is why Jedi start young and require a high amount of training. It's why Anakin and Luke weren't making things float all over Tatooine when they were young, and on the other end, why people were annoyed in TFA when Rey could suddenly do the mind trick with no training.
