Where can I find information on the encounter rates of Pokemon in various locations?

Some places, like Wayward Cave, literally ensue an encounter every 4 steps. Others, like Solaceon Ruins, can be easily navigated without encountering anything or using repels. Where can I find solid evidence for things like this?Edit: I’ve had two answers so far that don’t answer what I’m trying to ask. I’m not asking for info on how often a particular species appears in a wild encounter. I’m asking how often ANY Pokemon appears. I really don’t know how to rephrase it better.

According toBulbapedia, the encounter rate is determined by the simple formulaP = x/187.5, where x is the following:

Based on the Pokemon that are in the area, you can use the formula to get the chance a Pokemon will appear. The higher the chance is of a Pokemon appearing, the greater x will be, and therefore, the higher chance you’ll have to encounter a Pokemon. In Solacean Ruins, the only Pokemon there are Unown, meaning you have a 100% chance of encountering it. This means that x = 10, making the probability 5.33% of enountering Unown, and basically, 5.33% chance of encountering any Pokemon at all. In Wayward Cave, however, you have different encounter rates that will factor in, as there are more Pokemon to work with. With all these additional Pokemon, chance will increase, as you have the chance each Pokemon a certain percentage, and the summation of these percentages will equate to something decently high, which explains your Wayward and Solceon Ruins problem.

Also, this is partially luck based, evidently. You were probably just unlucky with your encounters in Wayward rather than Solaceon. There may have also been certain Pokemon that have abilities that alter encounter chances:
