Each Pokemon is different and not all evolve because they have reached a specific level (some evolve due to high friendship, being traded, getting an item used on them, etc.). Some Pokemon that evolve through level will evolve between levels 10 and 20, and some may not have their first evolution until the late 30s. Also, not all Pokemon evolve.
If you want a very accurate, satisfying answer, you will need to ask about a specific Pokemon.
