Ethnic Identity and Neighborhood Space

Personally I would have assumed that each and every ethnic identity would have kept to themselves. The map would be entirely and easily defined and divided by different ethnic identities. All people of the same ethnic identity would live with their own ethnic identity in the same neighborhood space. However, this was not entirely the case as it seems. There was nothing that confirmed my initial thoughts entirely. What I found out to be the actuality was the complete opposite of what I assumed. I didn't expect ethnic identities to be living among other ethnic identities in the same place. True there would be quite a massive groupings of the same ethnic identity here and there to make a rather big grouping, but overall they were all spread out all over the place.
Aside from distribution in the neighborhood space among ethnic identities, people of all different economical standings were spread out across the area just as much as, if not more than. The maps that I could make something out of showed a higher distribution between incomes/wages from next door to next door than ethnic identity was. Also, with such close quarters housing, there was no place for people to really mingle. There wasn't much space for the children to play as it was and if there happened to be places for the children to play, it was within the alleyways. So, I don't think there really was a relationship between ethnic identity and neighborhood space.
