Reading the desk
What each part shows
Choose a ZIP code or a borough, a complaint type if you want one, and a period of 7, 30 or 90 days. The desk then asks the data three questions: which complaint types were most frequent in that place, how many requests were created on each day, and which requests are the most recent. It opens on the last seven whole days in all five boroughs.
- Top complaint types lists the 12 most frequent types for the place and period, whatever type you chose. Press a row to see only that type; press it again to see all of them.
- Requests per day counts requests by the day they were created. A request with no ZIP code in the data cannot be counted under any ZIP code. The same counts are in a table under the chart.
- Most recent requests shows 10 at a time, newest first, with the type, the detail, the street, the responding agency, the status and the agency’s own resolution text. The house number is left out on this page.
- Noise: the city files noise under several types, such as residential, street and sidewalk, commercial and vehicle. “All noise complaints” in the type list adds together every type whose name starts with “Noise”.
Method
What this desk reads, and what it does not
Each view is answered by the city’s public dataset, 311 Service Requests from 2020 to Present (NYC Open Data, dataset erm2-nwe9), which your browser reads from https://data.cityofnewyork.us/resource/erm2-nwe9.json as you ask. Fetched: the newest request in the data (once per visit), the counts by complaint type, the counts by day and the most recent requests. Computed here: the period (whole days before the newest one), the total, and the chart drawn from the daily counts.
For scale: in the twelve months from 1 September 2025 to 31 August 2026 the dataset held 3,942,893 service requests under 198 complaint types. The most frequent was “Illegal Parking”, with 612,319. Counted 29 September 2026; the full table is on NYC 311 complaint types, counted.
Limits you should know
- The data runs about a day behind. The dataset’s own documentation says it is updated overnight with a one-day buffer: on a Thursday morning it holds everything through Tuesday and the early hours of Wednesday. That is why the newest day is left out of the counts here.
- A complaint is not a measurement. The documentation is plain about this: many noise complaints from one neighbourhood mean that more people complained there, not that it is the noisiest place in the city.
- Not everything is in it. The dataset holds only service requests that can be directed to a specific agency. It leaves out inquiries, and agencies with their own systems, such as the Housing Authority and the Department of Correction.
- The key is not your request number. The dataset’s Unique Key is different from the Service Request number given to the person who called, and that number is not in the data.
- Status and resolution are the responding agency’s words, as last updated in the data. The lists of expected values change over time.
- Times are New York time, exactly as in the data.
- The city’s data service limits how often one network may ask without a key. If it refuses, this desk says so, shows no numbers, and offers to try again.
- A long period can be slow to count. The city’s service can take a minute or more to count 30 or 90 days that nobody has asked it for lately. This desk says so while it waits; if a minute runs out, or the service answers with an error, it asks once more, and because the service keeps counting and keeps its answer, the second ask is usually answered in seconds.
Licence, and what you choose
The dataset’s metadata states no licence, and none is claimed here; the city’s terms of use for its sites are listed below. The ZIP code, borough, type and period you choose go only to data.cityofnewyork.us, as the query itself, sent without cookies or a referrer. Nothing is stored on labs.llc, and the site’s analytics receive the page’s address, never what you chose.
The city’s own lookup is the authority. To follow a request you made, use Look Up Service Requests at NYC311 with your Service Request number. This page reports public records and does not file, change or speed up a request. The desk is part of the New York City guide, beside the NYC restaurant inspection lookup.
