Using data collected by PokeRadar, PokemonGoChamp has crunched the numbers on Pokemon GO spawn rates and published its finding via an unofficial spawn rate chart.
The percentages were calculating during a one week period across 100 million data points. The chart lists spawn chance, average spawn points and times when Pokemon are most likely to spawn.
Pidgey has the highest spawn rate at almost 16%, followed by Rattata at 13% and Weedle at 7%. Dragonite has the smallest spawn rate at 0.0011% followed by Mr Mime at 0.0031% along with Muk and Charizard.
