Data Question

Mayor's Office of Operations (OPS)

Hi,

I am using the Local Law 79/2022 - Temporary Housing Assistance Usage database. I noticed that for May 2023, certain indicators are missing. Specifically, in May 2024, the values for all variables dealing with families and families with children (I'm filtering the dataset to only view observations where category = "Total number of individuals utilizing city-administered facilities")

If you happen to know why the DHS counts for May-December 2023 are higher than those on the Coalition for the Homeless's website, I'd also appreciate any insight! (Link to web archive of last years data: https://web.archive.org/web/20240306042152/https://www.coalitionforthehomeless.org/wp-content/uploads/2024/02/NYC-Homeless-Shelter-Population-Worksheet-1983-Present2.pdf)

Additionally, does the data go back further than May of 2023? If I wanted to access DHS data on shelter population before then, is there a different dataset that could be used?

Thanks you very much for any help you can provide!

Data Question

Department of Parks and Recreation (PARKS)

Hello,

I am reaching out to inquire about data related to the Parks Inspection Program. I would like to conduct an analysis using the public restrooms inspection data but I have not been able to locate data related to WHEN those inspections took place. I do see an inspection number but would like to utilize this information along with the date to do a time series analysis. Is this data currently available? If so, how can I access it?

Thank you.

To find the date for when the inspection took place you can join this dataset to the Parks Inspection Program – Inspections dataset on inspection number.

I am doing a statistical study on water usage over time in NYC and am looking into why water usage has been going down despite population growth. I need to incorporate other factors (i.e. price of water, water efficiency, etc.) that is likely causing this trend. Do you have any insights into what variables specifically that might be? And even better, any other data links to provide for this?

I understand that 311 calls were made free for people incarcerated in city jails, and 311 is a common avenue for incarcerated people to initiate the grievance process. However, when I look at this dataset, I don't see any 311 calls reported from the Department of Correction. I'm wondering why these calls aren't part of this dataset, and if there is another way I might access them. Thanks for any insight you're able to share.

Rolling sales tables are based on the year and on the last 12 months. The problem is that there are no rolling sales tables for 2024 and the last 12 months table has records between April 2024 and March 2025.

Hi, I noticed that the .nyc domain registrations dataset does not have descriptions for columns, or a data dictionary. Could these be added?

And, are records ever deleted from the dataset? For example, if a .nyc domain is registered, and then later the registration lapses (for example, if a payment was not made), is the .nyc domain removed from the dataset? Or, if it's re-registered later, does the domain registration date value change?

Thank you,

Data Question

Office of Administrative Trials and Hearings (OATH)

How can you locate docket level information in the database about a hearing when there is a "group" number for a group of summonses, rather than a 9-digit summons number? For example, the code *** refers to a single hearing date where multiple summons are then discussed during the same hearing.

OATH Hearings Division Case Status

https://data.cityofnewyork.us/d/jz4z-kudi

OATH Hearings open dataset is not categorizing summonses into specific groupings for hearing pool purposes. However, a respondent may have multiple summonses; therefore, it is possible to query the dataset by respondent name, which may return more than one summons. Nonetheless, different respondents may share identical names, so the query results cannot conclusively determine whether multiple summonses belong to the same individual. You may also filter a group of summonses based on the Date Judgment was Docketed within a specified period. According to the Office of Administrative Trials and Hearings (OATH), the Date Judgment was Docketed refers to the date on which the judgment was officially entered into the court’s docket.
Thank you.

I wanted to inquire about the subway lines dataset. It appears that the dataset for subway lines is no longer available on via the open data website. I have several links to the subway line dataset (The one provided is from CityofNewYork's Github repository) but the link is either broken or the dataset is no longer available. I've also searched the Open Data website but can not find the subway lines dataset. Is it possible that there was a issue and that dataset did not properly populate on the website or was the dataset deliberately removed? If it is intentionally removed from public access, what is the reason/justification for this? Thank you

The NYC Housing Vacancy Survey Data for 2011, 2014, and 2017

Thank you for your inquiry. 
 
The files you are referring to are known as 'fixed width' files. Fixed-width files are ones where every field has a specified length to store data in. On our public website where the data files can be downloaded, we also have links to their related 'record layout' documents. The record layout document has a field called 'character position' that contains the length of each data field in each field. If you know how to code, you can leverage that information to write a program in your preferred coding environment (e.g. Python, R, SAS, etc.) to process the .txt files and create an output in tabular format for further analysis.
 
If you don't know how to code, you are welcome to leverage available online resources to help you get started and create the code you need.

Hope this information puts you in a better position to independently use these large text data files for your analyses.

For our Data Mining class project we want to answer the following questions:
What are the most common contributing factors to motor vehicle

Which locations in NYC experience the highest rates of motor vehicle
collisions? What contributing factors do we see associated with
specified locations? Are there areas with higher injury and fatality
rates, if so, why?​

When do we see the most collisions occur? Are there more accidents
around seasonal events or at certain times of the day?​

What types of vehicles are most frequently involved in collisions? Do
certain vehicle types contribute more to the severity of the accident?

The problem is we noticed there is a lot of missing data for street name, borough, location etc. How do you address this in your analysis?

Data Question

Department of City Planning (DCP), Department of Buildings (DOB)

Hi! I have a few questions about how to find newly filed building permits in NYC.

It's my understanding that DOB NOW Build is the best place to find the latest and most up-to-date information on DOB permitting. Is it still worth querying BIS datasets like DOB Job Application Filings (https://data.cityofnewyork.us/Housing-Development/DOB-Job-Application-Filings/ic3t-wcy2/about_data) if I am only looking for the most recently filed data?

More specifically, my use case is to find buildings in Brooklyn that are planning new commercial and retail space. My current approach is to search DOB NOW Build Job App Filings for:
- job type = new building
- borough = brooklyn
- general_construction_work_type_ = Yes

I also filter for total_construction_floor_area > 20000 because I'm looking for larger buildings.

This works well to get a new dataset, but the info there doesn't tell me anything about commercial/retail space, as far as I can tell. So next I am attempting to get this data from PLUTO (https://data.cityofnewyork.us/City-Government/Primary-Land-Use-Tax-Lot-Output-PLUTO-/64uk-42ks/about_data). However, it occurs to me that PLUTO may be referring to *existing* buildings on the specified lot, rather than the *new* buildings being planned by the new building permit. Is that a correct assumption?

If so, could you advise me on better ways to obtain this data please? I would also like to consider jobs that are not new buildings but are major renovation that will include commercial or retail space. Thank you so much!

DOB Job Application Filings

https://data.cityofnewyork.us/d/ic3t-wcy2

From DCP: Yes, PLUTO data is about existing uses, not planned. We source our data from DOF.
From DOB: The correct data sets to reference are primarily DOB NOW: Build - Approved Permits and DOB NOW: Build - Job Application Filings. In some cases, there can be permits requested and issued in BIS on new building applications that were filed in BIS, however that set is small and will continue to decline.

Good morning,

Thank you your request on Citywide Mobility Survey- Trip 2022 dataset. In the survey, the question used this value was: “How much was the total fare for the ride? Round to the nearest dollar. Please include any tip.”
The answer/numerical value should include the full ride amount including tip. Hope this helps.

Data Question

Department of Environmental Protection (DEP)

Hello! I was curious to know why this data is updated quarterly, and if it is an automatic API or data source, if it would be possible to get it updated more frequently? I ask because I also know about this data source that shows some of the same data, but on a real-time basis, and I would love to see these two levels of granularity combined to one dataset.

Does the system uptime column include times when the system is "partially operational"?

Is the RNG Production column the total gas that was given to National Grid, or does it include the gas that was used to heat Newtown Creek?

Does this data include the flares from National Grid at Newtown Creek? Or are these only the flares from the DEP at Newtown Creek?

Thank you!

Data Question

Department of Buildings (DOB)

Hi I'm wondering how I can relate a permit from the issuance permit dataset back to the approval permit dataset. I though the Job # from Issuance dataset and Job Filing Number from the approval dataset would match up but that doesn't seem to be the case.

DOB NOW: Build – Approved Permits

https://data.cityofnewyork.us/d/rbx6-tga4

These two data sets you've included links to are derived from two different systems of record. DOB NOW Build Approved Permits contains DOB NOW system records. DOB Permit Issuance contains BIS system records. The job numbers and permit numbers are not of the same structure or intended to be connected other than by their associated BIN.

Hello,
I am trying to use your dataset for my study and I couldn t find anywhere the meaning of "L" as VIC_SEX category.
Indeed, I found "Victim’s Sex Description (D=Business/Organization, E=PSNY/People of the State of New York, F=Female, M=Male)" but there is no explanation for the presence of "L".
Would you mind telling me what it stands for?
Thank you very much,
Have a lovely day,

Data Question

Department of Parks and Recreation (PARKS)

I am trying to calculate the area in square feet of each of the synthetic turf installations in NYC. What is the format of the data in the "Shape" field, e.g., GeoJSON, EWKB, LiDAR? It is described as "Geometry of the synthetic turf system" and elsewhere on the NY Open Data site is described as a "vector GIS dataset" but I am unable to parse the data using Excel or Python. Do I need a specialized program to interpret the data in this field?

Synthetic Turf Fields

Our apologies for the delay in responding to you – we were working on updating the dataset. It can be exported a GeoJSON that you can pull into a Python environment. Please note that a new field (FeatureStatus) has been added to this dataset to indicate the status of the synthetic turf system, so all records are not currently active. Thanks!

Data Question

Taxi and Limousine Commission (TLC)

I am a student at *** currently researching traffic forecasting on Uber in New York City. With your reference to the TLC Trip Records User Guide, the Uber base number should be the following:

[ ***** ].

However, those base numbers seem no longer available in the records after some months in 2019. I wrote a Python code to search for the trips for Uber based on the Uber base number listed above, results can be found before 2019. However, from 2019 onward, no base number in the For-Hire Vehicle Trip Records matches the base number in the list mentioned above. Therefore, I am enquiring about the current (or from 2019) "Dispatching_base_num" that is operated by Uber.

Is that possible that the Uber trip data is only available in the High Volume For-Hire Vehicle Trip Records? Or it can also be found in normal For-Hire Vehicle Trip Records?

https://d37ci6vzurychx.cloudfront.net/trip-data/fhv_tripdata_2024-01.parquet

Prior to February 2019, all high-volume trip records appeared in the For-Hire Vehicle (FHV) trip record datasets, which is where you found Uber trips with the base numbers you provided below.
In 2019, the High Volume (HV) FHV license was created for companies doing 10,000+ trips per day. Currently, only Uber and Lyft are licensed in this category. From Feb 2019 onwards, all HV trip records are found only in the HV trip record datasets (Uber trips can be identified with the `hvfhs_license_num` = ‘HV0003’).
Hope this clears things up.
