Great idea, but you need some mentoring in categorization. You have some that are typos and some that are connected to high level categories. The idea is not to create a category for every possible search term. I think every single one of your "red" categories need to be removed. Also the "United States Place Studies" and the "One Place Studies." You want to only connect (what categories do) to the lowest category.
You can add the category: [[Category: New York Place Studies]] and [[Category: Bronx County, New York, Place Studies]].
I do have some people to add to your study.
