How this category is extracted
What counts as service inquiries: Calls and submissions logged as informational inquiries, status checks, or general questions about city services rather than reports of problems requiring a field response. High counts here typically indicate a city's 311 system captures all resident contacts, not just actionable service requests.
In Chicago’s raw 311 feed, the following 3 service_type values roll into service inquiries:
- 311 INFORMATION ONLY CALL
- Water Lead Test Kit Request
- Water Lead Test Visit Request
To reproduce these counts against the raw feed
SELECT count(*)
FROM <chicago_311_raw>
WHERE service_type IN (
'311 INFORMATION ONLY CALL',
'Water Lead Test Kit Request',
'Water Lead Test Visit Request'
)Analyst tip: Chicago's '311 INFORMATION ONLY CALL' is the single largest contributor — roughly 1 million rows. Edmonton files informational contacts under 'General Information', 'General Inquiry', 'Routes and Schedules', 'Tax Account - Inquiries/Requests', and related types. Baltimore uses 'ECC-Information Request'. Somerville logs them as 'Information - Various Other', 'Information - Parking', and 'Information - DPW'. Philadelphia uses 'Information Request' with descriptive subtypes. Calgary uses department-prefixed inquiry types (AT - Property Tax, CT - Bus Route, etc.). Not all cities publish this category — cities that only log actionable service requests will show zero rows here.
