Since February 2022 Chicago has measured respiratory viruses in its sewers at seven sewershed sites, weekly. Read whole - 6,692 rows, 237 weeks - the file shows four very different ledgers: SARS-CoV-2 with 51 Very High weeks, Influenza B with exactly one, RSV peaking the week that straddled New Year 2024 - and every virus at Minimal in the newest week. Concentrations, never illness counts; every caveat quoted from the file itself.

The TIF annual reports now publish a deal-by-deal jobs scorecard: projections beside actuals for every subsidized redevelopment agreement. Read whole - 110 rows, 2022-2025 - the 2025 reports project 1,688 permanent jobs with 543 in the actual column so far, one agreement promised 70 jobs and reports 130, another promised zero and reports 59, and one projection reads exactly 2.5 jobs, printed as filed. Snapshots, not verdicts - and the file cuts both ways.

Chicago runs its own air-sensor network now: 286 sensors carrying all 77 community-area names, 2,544,089 hourly readings since July 2025, read whole. The PM2.5 record book belongs to two UTC dates - July 16 and 17, 2026, with a 486.8 microgram hour and 96 percent of every 100-plus sensor-hour ever logged - beside an ordinary record where such hours are 0.45 percent of everything. Not for regulatory purposes, says the file itself, and this page keeps every caveat.

Chicago's height story, with receipts: the streets themselves were raised four to five feet on average in the 1850s, a building among the world's first skyscrapers went up - and came down - at LaSalle and Adams, the Willis Tower held the world title for nearly 25 years, and the city's own footprint file crowns a different king: two stories, 198,439 times. Eight vertical records, every one traceable.

Chicago's alternative-fuel file lists 398 stations, and the short answer is direct: 350 public electric stations marked Available, 283 of them posted 24 hours. The longer answer lives in the columns - 1,043 Level 2 ports against just 291 fast ports, 26 network labels, four ZIP codes holding 38 percent of everything, and a last-confirmed date on nearly every row. A decision-guide read of the whole file.

Why does your block need a permit while the next street over doesn't? Chicago's residential permit parking is assembled from 1,937 active zones created by City Council legislation - and the file runs small: the median zone is two block-sides, 238 zones are a single segment, zone 383 sprawls to 653. One in seven active segments is an unsigned buffer where permit rights exist without that zone's signs, 17 percent of zone-street pairs cover one side only, and 503 segments sit rescinded. Prices and rules live with the City Clerk.

Seven things about Chicago deep dish, each traced to a named source: a fall 1943 birth per the Encyclopedia of Chicago, an origin Uno's page credits to Ike Sewell while the reference work names three partners and no inventor, a 600-degree recipe, pizza in Chicago since the 1890s, a first Lou Malnati's that opened in Lincolnwood on St. Patrick's Day 1971, a Gino's East opened by two taxi drivers and a partner - and 2,445 active licenses with PIZZ in the name, counted by us. No pizza is ranked; no restaurant is recommended.

Seven things under Chicago, each traced to a named record: streets raised four to five feet on average in the 1850s, buildings lifted one owner at a time, a forgotten freight-tunnel network that flooded the Loop with 250 million gallons of river water in 1992, a Pedway linking more than 40 blocks, a separate government's 110 miles of tunnels up to 300 feet down, and the 811 file that logs what diggers hit. Every quote verified against its source; every figure of ours labeled.

The Chicago Park District - a separate government from the city - keeps a reservation ledger of 142,366 rows, 2012 into future-dated 2026 bookings. Read by its own labels it is three calendars: 96,765 permit rows (98 percent marked Approved; 13 denial-labeled rows in fifteen years), 40,553 administrative reservations, and 5,048 venue rentals, 1,867 of them weddings. Athletic training is one permit row in three, and the most-reserved space in the file is a greenhouse. No applicant name was queried.
