Monthly animals & pests requests
How many animals & pests 311 requests Chicago residents file each month.
How this category is defined
What counts as animals & pests: Complaints about loose, injured, or dead animals on public property; dog bites; wildlife concerns (coyotes, raccoons); and rodent or pest sightings.
In Chicago’s raw 311 data, the following 7 service_type values are counted as animals & pests:
- Dead Animal Pick-Up Request
- Nuisance Animal Complaint
- Pet Wellness Check Request
- Report an Injured Animal
- Rodent Baiting/Rat Complaint
- Stray Animal Complaint
- Vicious Animal Complaint
To reproduce these counts against the raw feed
SELECT count(*)
FROM <chicago_311_raw>
WHERE service_type IN (
'Dead Animal Pick-Up Request',
'Nuisance Animal Complaint',
'Pet Wellness Check Request',
'Report an Injured Animal',
'Rodent Baiting/Rat Complaint',
'Stray Animal Complaint',
'Vicious Animal Complaint'
)Analyst tip: Austin prefixes everything 'Animal Protection - ...'. Calgary uses 'AS -' for animal services and also files rodent calls under 'Parks - Wildlife Management'. NYC does not currently have a dedicated animal service_type in our mapping — rodent and wildlife complaints land under building or street categories in that city.
