Not really. If you expect that a growing population will use transit more to avoid congestion, you would expect per-capita transit use to grow with a growing population.
In sparse populations where everyone has a relatively large family farm, you would not expect as much transit because the number of people to pick up along a given route would waste vehicle capacity.
