I have a script that runs every night and mirrors the data into a [datasette application](https://puddle.bunkum.us/service_requests), where public users can run SQL queries. The data for the ward comparisons tables comes from the datasette instance, and [here is the SQL query](https://observablehq.com/d/4231365da7fff12d#ttc). A few key points about how we are filtering the data: 1. We looking at service requests opened in the last 365 days, 2. that have been completed, 3. that took more than 24 hours to complete, 4. that were opened by a phone call, on a website, through a mobile application, or by an aldermanic office, 5. and which were one of the 13 most common service requests types, i.e. service types which had at least complete request in each of the 50 wards. The parameters for the ward multiplier map come from an estimated model, the [details of which can be found here](https://github.com/fgregg/service_requests/blob/main/estimate_ward_effect.R). It uses the same filters of the data.29:T481,with days as ( select SR_TYPE, WARD, cast( julianday(CLOSED_DATE) - julianday(CREATED_DATE) as integer ) as time_to_completion from service_requests where created_date >= ${form.start_date.toISOString().substring(0, 10)} AND created_date <= ${form.end_date.toISOString().substring(0, 10)} and SR_TYPE IN ( 'Abandoned Vehicle Complaint', 'Alley Pothole Complaint', 'Building Violation', 'Garbage Cart Maintenance', 'Graffiti Removal Request', 'Inspect Public Way Request', 'Pothole in Street Complaint', 'Rodent Baiting/Rat Complaint', 'Sewer Cleaning Inspection Request', 'Street Light Out Complaint', 'Traffic Signal Out Complaint', 'Tree Debris Clean-Up Request', 'Water On Street Complaint' ) AND STATUS = 'Completed' AND time_to_completion > 0 AND WARD IS NOT NULL AND ORIGIN IN ( 'Phone Call', 'Internet', 'Mobile Device', 'Alderman''s Office' ) ) select SR_TYPE, WARD, time_to_completion, count(*) as count from days group by SR_TYPE, WARD, time_to_completion2a:[{"id":"f5bea33e3b8de8a4a7522ddba707a8c670d63dfe3d3af96e4dffe51564b203b0f9f9b3778aee4c478fec14b766dcfa554b0b0ff23ef0c3b825cc736a34fa12ef","href":"https://static.observableusercontent.com/files/f5bea33e3b8de8a4a7522ddba707a8c670d63dfe3d3af96e4dffe51564b203b0f9f9b3778aee4c478fec14b766dcfa554b0b0ff23ef0c3b825cc736a34fa12ef","name":"Boundaries - Wards (2015-2023).geojson","type":"application/geo+json","lastModified":1672193784893.86,"size":2524138},{"id":"744366ea7b04f3c1e365c435f0a7c05e3d5f1dd2a83ef55c1d1843a967c903c59cc49fe4eeca914addf016ab33391f595305d5822030c9ecbb6090a01d7f5e3a","href":"https://static.observableusercontent.com/files/744366ea7b04f3c1e365c435f0a7c05e3d5f1dd2a83ef55c1d1843a967c903c59cc49fe4eeca914addf016ab33391f595305d5822030c9ecbb6090a01d7f5e3a","name":"ward_parameters@2.csv","type":"text/csv","lastModified":1672322679491.325,"size":5688}] 25:{"id":"4231365da7fff12d","slug":"differences-among-chicago-wards-in-how-long-it-takes-before","title":"Differences among Chicago wards in how long it takes before city service requests are serviced","thumbnail":"532278d6f0fdfd02c2edd860019c6a158faa639d6beae32b65d6374937d43917","access_level":"public","create_time":"$D2022-12-28T02:13:11.694Z","update_time":"$D2023-01-21T17:08:18.003Z","view_time":null,"first_public_time":"$D2022-12-28T02:13:11.694Z","has_unpublished_edits":null,"fork":false,"stars":1,"starred":false,"owner":{"type":"team","id":"97541738f61a2563","login":"fgregg","name":"Forest Gregg","avatar_url":"https://avatars-next.observableusercontent.com/7d00689d4df1c6365c47d99b27c8a37a6722b76a620b6df0af6b0b6fbd3a114d","tier":"starter_2024"},"version":698,"publish_version":null,"role":null,"authored":false,"authors":[{"type":"individual","id":"e11e15c775d16887","login":"fgregg","name":"Forest Gregg","avatar_url":"https://avatars-next.observableusercontent.com/7d00689d4df1c6365c47d99b27c8a37a6722b76a620b6df0af6b0b6fbd3a114d","tier":null}],"members":[{"type":"individual","id":"e11e15c775d16887","login":"fgregg","name":"Forest Gregg","avatar_url":"https://avatars-next.observableusercontent.com/7d00689d4df1c6365c47d99b27c8a37a6722b76a620b6df0af6b0b6fbd3a114d","tier":null,"role":"editor"}],"comments":[],"custom_thumbnail":false,"trashed":false,"lapsed":null,"subscribed":null,"forks":0,"collection":{"id":"33a9d8b2788bd90f","slug":"blog-transfer","title":"blog transfer","owner":{"id":"97541738f61a2563","login":"fgregg","name":"Forest Gregg"}},"type":"notebook","body":{"titling":"auto","title":"Differences among Chicago wards in how long it takes before city service requests are serviced","cells":[{"id":0,"value":"# Differences among Chicago wards in how long it takes before city service requests are serviced\n\n\nThis notebook explores differences among Chicago wards in how long it takes the city to complete requests for service made in the last 365 days (by default).\n\nGenerally, the city responds much more quickly to service requests in ward 42, which covers the central business district.
