This is a map of champaign-urbana schools (Champaign Schools.pdf), color coded by school type (public/private) and 2004-2005 performance for public schools, against a backdrop of 2000 census block by percentage of minority residents in CU. This is in response to the thread: http://www.illinipundit.com/2006/10/16/charter-school-for-champaign-boys#comment and http://www.ucimc.org/node/497.
The school layer does not differentiate what level of schooling (k-5, middle, jr, high).
It does, however, indicate whether or not the school made AYP in 2005, if the school is a “spotlight” school or an “AEWS” (Academic Early Warning) school per the interactive schools report from NIU, or no indication for either (“OK”).
Non-spatial data for the public schools came from: http://iirc.niu.edu/.
Spatial data (street addresses) for all schools came from: http://Illinois.publicschoolsreport.com and http://Illinois.privateschoolsreport.com. Street addresses for all schools were geocoded to a street shapefile from the Champaign County Regional Planning Commission (CCGISC), current as of Oct ‘06. Minor local streets were left out for clarity, major roads were left in for visual spatial reference.
2000 demographic data (spatial and non-spatial), water features and rail features came from US Census.
Minority percentage was derived for each census block by creating a field for “(POP2000 - POP_WHITE) / POP2000,” and then equal-break visualizing the blocks in 5% intervals, with darker shades indicating a higher percentage of minorities in that block.
Census blocks with no color indicate that there is a 2000 population of “0” in that block.
I have no idea of the spatial makeup of each school (ie, what percentage of students come from what part of town, or demographic makeup of each school), so no correlation should be inferred between location of a school, performance of a school, and demographic breakdown within each school.
There is no intentional political motive behind the map; it is designed to be an unbiased point of reference for the blog users to work with, so we’re all on the same sheet of music.
UDPATE BY IP: The file is here. I'm not sure why anonymous users couldn't see it before , but I'm trying to fix it.
UPDATE BY IP #2: Fixed now. You can view the file just below the post, whether you're anonymous or not. I love Drupal!
**UPDATED: Includes a map (Champaign Density.pdf) with the same school and infrastructure/natural data, but I've changed the census block visualization from equal-interval minority percentages, to natural-breaks (Jenks) population normalized by area (acreage). This will give a pretty accurate idea of density only (no race demographics), but please note that the color ramp for density is NOT equal-interval**
**UPDATED: Includes a map (Champaign Parcels Schools.pdf) of schools with a backdrop of assessed residential property values within the boundaries of Champaign, Urbana and Savoy, color ramped such that darker is more expensive. The purpose of using property values is to have a subjective indicator of household net worth and income. I have worked pretty hard to get all residential properties on there, but there's clearly some missing rental properties, especially around campus (as you can imagine, a shapefile like this is HUGE, and a monster to work with - not to mention that the fields in the file aren't intuitive). I believe I have all owner-occupied properties on there. I have excluded properties with no assessed structure. I believe that it's "good enough" for what we're doing here. Note that the color ramp is for property values is NOT equal-interval. This is the last map I'm going to do for this "project."**
