creating a city in shadowrun

Creation of a city and the setting:

Let the players create their characters, then go over the city, letting everyone deside how its set up and where their character fits in, creating the background around their characters. Everything that is mentioned is strong presenses, there is always a little of everything in every city but some cities have more than others about certain things.

Things that can be important to remember:
Runners, what kind of jobs do they tend to take?
Faces
Magicians
Adepts
Hackers
Riggers
Street Samurai
Matrix, how integrated is that in the society?
Astral Plane, how is this affecting the society?
Rasism, how likely is this? (rasist organization or pro-meta activists?)
Dragon, likelyhood of presense
Religion, any strong presense?
Ghosts, ghouls and spirits, any strong attraction for undeads?
