CPS's school-by-school progress file for SY2425, read as recorded: chronic truancy at 37.6 percent for the median school (62.6 at the median high school), 51 percent of schools in the culture survey's top two levels - and rating columns that are mostly empty, with no school carrying a growth rating. No school named, nothing re-graded.
Chicago's TIF deal file, read whole: 767 council-approved redevelopment and intergovernmental agreements since 1986, $6.46 billion in approved subsidy against $24 billion in project costs. The CTA holds the two biggest; The 78 leads 2026; only 30 percent carry a completion certificate. Approvals, never disbursements.
CDOT's own patch ledger, read whole: 2,756,235 potholes filled across 239,812 completed jobs since 2018 - and 2026 through August 17 has already out-filled all of 2025. The median job runs request-to-patch in about five days; every area's count mapped; completed-jobs boundary stated.
The Loop holds 77 of the 409 placed entries on Chicago's individual-landmark register - one in five - with the Near North Side second at 43. Twelve areas listed, because the cut lands mid-tie at 12; districts counted separately; every tie shown at shared rank.
The 1st Ward leads Chicago with 276 active shared-housing registrations - the city's term for Airbnb-style rental permission - with the 44th and 27th behind it and the top ten wards holding 46 percent of the citywide 3,852. Ward grain by design: the file's host names and addresses were never touched.
Austin leads Chicago with 6,777 two-to-six-flat parcels on the Assessor's 2026 roll, ahead of West Town and Logan Square - the top ten areas hold 38 percent of the city's 119,978. Class-211 parcels, not buildings, with the shrinking-stock arc in the companion analysis.
The parking-meter concession read from the documents the city posts: a 75-year lease from February 13, 2009 priced at exactly $1,151,355,186, the audited true-up ledger - $160,953,305 paid by the city through 2024 - the operator's $188.7M 2025 revenues, and the December 2025 agreement by its owners to sell, awaiting Council action as of the audit's April 2026 cutoff.
West Town leads Chicago in bike-rack installation records since 2015 with 739, the Loop nine behind - and the top ten areas hold just over half the file's 9,448 mapped records. No complete rack census exists in any city file; this list ranks the records that do.
Eight of Chicago's high-volume 311 request types, ranked by median days from creation to recorded closure: traffic signals in about three hours, graffiti under a day, potholes about five days with an 89-day slow tail, garbage carts about 15 days. 793,774 requests timed.
Chicago's bike-rack records come in two files that were never merged: 9,449 records of installs since 2015 - reaching all 77 community areas, led by West Town and the Loop - and a 5,164-row file frozen in 2011. More than half the current records carry no type, the quantity column's unit is unstated, and no complete rack count exists in either file.
