A user from Reddit has suggested an analogy about a nest point in Pokemon Go. It has been noted from his compilation of information from 3.15 Million spawns and around 18,000 spawn points that a certain nest point can actually spawn 25%, and there is also a 75% chance of it to behave similar to a normal spawn point. However, this information is somewhat leading to the conclusion that there are no spawn points that can disproportionately spawn an evolved Pokemon.

According to Otakukart, there is approximately one out of 3000 spawn points that are also nest points. These special spawn points do have a related nest Pokemon. It is also said that all nest Pokemon are Pokémon that have not yet evolved.  A nest Pokemon cannot spawn into an even more evolved form. Some of the nest points may come out during isolation, or may also arise in the near nest points. The nest points also have trends to have the same nest Pokemon as nearby nest point, therefore this forms what is commonly known as nest. For the frequency of evolved spawns, most evolved Pokemon will always spawn in the same location as its base form.  There are a few exceptions, such as six percent of Dratini become Dragonair.

Eeveelutions are absolutely rare. Based on the reports from The Country Caller, rare spawn points can usually spawn a good quality Pokemon. These might be because there are some spawn points that are from better biomes. There are also some spawn points that are considered as nest points of a rare nest Pokemon. Some of the spawn points can be considered both. For example, from the 18k spawn points, 1k nest point were removed, thus only 17k spawn points were left. In every spawn point, there is a number of times an evolved Pokemon had spawned in a spawn point.
