Do certain Pokemon types appear more often in some locations?
Various reports claim that Pokemon are more likely to be found in their appropriate environments, such as water types near water. Is this true, or is it just observation bias with pseudo-random placement?
If true, what are the preferred places to find each type?
(Bug, Dark, Dragon, Electric, Fairy, Fighting, Fire, Flying, Ghost, Grass, Ground, Ice, Normal, Poison, Psychic, Rock, Steel, Water)
Pokemon spawns are very much affected by location.
The real world is split up into a number of biomes. Spawn chances, rates, and available Pokemon are very much biome dependent. This data is likely pulled from Google Maps and Ingress, with some minor alterations.
For example, it is far more likely for a Muk to spawn in an Urban environment than it is for it to spawn in a Meadow.

It's true to an extent. Walk by river, you'll see lots more magikarp and psyducks, forests seem to contain grass type/normal type/and pikachu's, towns are generally bug type/normal type/flying type. Rock types are pretty random, haven't really found a good spot to farm them yet, same for electric and fire. They are seen pretty randomly. I don't know about ghosts being near graveyards, but I know you'll find them at night randomly as well.
