1 is OK as "The number of restaurants is disproportionate to the size of the population" although that doesn't tell you whether there are too many or too few restaurants.
2 is messy, overly wordy and not natural at all. Neither "scatter" nor "to be segmented" work here (the latter doesn't really work anywhere).

I would go with something simple like:

- There are more restaurants than necessary given the size of the population.
- The city has more restaurants than necessary.
- The city has too many restaurants and they suffer from a lack of customers.
