A Primer On Critical Data Literacies For Social Policy
Begin ↓Understand how digital data systems like 311 shape homelessness policy — and what that means for social workers.
Ground our discussion in key concepts from the literature, then explore several ways to interface with NYC 311 data and examine how homelessness is measured and represented within it.
Explore additional tools for thinking about spatial justice and the relationship between space, data, and homelessness policy.
Before diving in, consider these questions — on your own or with a group:
What counts as data, and who decides?
The word "data" is the Latin plural of datum. Here's how Merriam-Webster defines it:
Factual information (such as measurements or statistics) used as a basis for reasoning, discussion, or calculation.
"the data is plentiful and easily available" — H. A. Gleason, Jr.
Information in digital form that can be transmitted or processed.
Information output by a sensing device or organ that includes both useful and irrelevant or redundant information and must be processed to be meaningful.

Data-driven policy making uses ICTs to capture the benefits of new data sources, and to support collaboration with relevant stakeholders and citizens. In the literature on evidence-based policy making, three types of evidence are considered relevant: "systematic ('scientific') research, program management experience ('practice'), and political judgement."
Data-driven policy making acknowledges the importance of these types of evidence, but can be distinguished from evidence-based policy making, since it is mainly concerned with the inclusion of big and open data sources into policy making as well as with co-creation of policy by involving citizens. Data-driven policy making is not only expected to result in better policies, but also aims to create legitimacy. Involvement of citizens in a data-driven policy making process is especially important since public data and statistics are increasingly met by citizens' distrust.

Data justice is an approach that redresses ways of collecting and disseminating data that have invisibilized and harmed historically marginalized communities. For decades, if not centuries, data has been weaponized against BIPOC communities, in particular, to reinforce oppressive systems that result in divestment and often inappropriate and harmful policies.
Data justice aims to capture forms of knowledge and lived experiences that are community-centered and community-driven to counter the systemic erasure and harm perpetrated on BIPOC communities via oppressive data practices. The fundamental premises of data justice are that data should:
"We argue here that individual social workers and the social work field are responsible to apprehend and to protest advancing technological mechanisms of disenfranchisement. Although some social work educators are committed to infusing computational and data science tools into social work training and curricula, professional research, practice and training must attend not simply to the acquisition of skills but also to the application of new technological tools and currencies to protect or erode human rights."Goldkind, L., Wolf, L., & LaMendola, W. (2021). Data justice: Social work and a more just future. Journal of Community Practice, 29(3), 237–256. Google Scholar
"Data literacy is a term that is in relatively common use and usually defined as the knowledge and skills citizens need to participate in the digital world. However, in the context of data justice, the capabilities required are not simply those enabling participation — instead citizens need to be able to understand and reflect critically upon the implications of datafication. As Sander (2020a) has argued, 'Datafied societies need informed public debate about the implications of data science technologies.'"Ballantyne, N. (2023). Advancing data justice.

What does data justice look like for persons experiencing homelessness?
Requires "unduplicated counts" of homeless populations. Beginnings of estimates like the HOPE Count.
Renews McKinney-Vento, establishes the Continuum of Care (CoC) model. Targeted housing outreach requires more data collection.
Introduction of data-driven rapid rehousing strategies.
COVID-era changes intensify data collection requirements.
Attempts to dismantle Housing First policies at the federal level.
Managed through shelter population counts.
Development informed by shelter counts, community needs, data on units & affordability.
Street homelessness, encampments, and "quality of life" issues related to homelessness all become data.
CompStat (NYPD) and HOME-STAT (DHS/DSS) both report daily on street homelessness and related measures.
Citizens use tools like 311 to report concerns — which feed directly into policy and enforcement responses.
First use of 311 — designed to divert "non-emergency calls" away from 911.
Launched under the Bloomberg administration.
Integration of photos and videos into calls/requests.
NYC 311 joins Skype and Twitter.
Open311 Application Program Interface established as an open technical standard.
Text messaging capabilities added to NYC 311.
Social media and chat channels go 24/7.

The 311 data infrastructure is built on the 'installed base' of the 311 reporting infrastructure and thus inherits its limitations (Star 1999). Not everyone that experiences a problem in the city reports it to 311. New Yorkers do not report issues to 311 when they do not know that the service exists, when they do not have access to the infrastructure to report to 311, or when they don't want to take the time to bother with inputting the necessary information into the service.
Perhaps most notably, 311 does not accept calls about NYC Housing Authority (NYCHA) properties, which comprise the largest public housing system in the country. As a result, 311 does not record any housing complaint data about some of the lowest-income areas in the city. 311 data only count issues where and when they have been reported to 311, not where and when issues have actually occurred.

We will explore four layers of 311 data interfaces. As you work through each activity, keep these questions in mind:
Visit the NYC Open Data Portal. Explore the interface. What do you notice?
Search "homeless". What do you see?
Search "311 Service Requests" and open the dataset "311 Service Requests from 2010 to Present." Examine it. What do you see?
Open the Data Dictionary attachment. What do you see? Look at the complaint types under the Department of Homeless Services.
Click "Look Up Service Requests", then scroll to "See Service Requests on a Map."
In Location, type "Silberman" and select "HUNTER COLL SCHOOL OF SOCIAL WORK." Set the range to 2000 feet.
In Date, set the "From" field to 1/1/2025.
In Problem Area, select "Homeless." In Problem, select "Homeless Person Assistance."
Explore the map. Look around at the service requests. What do you see? What don't you see?
Return to the map. Use the same location (Hunter College School of Social Work, 2000 feet) and date range (from 1/1/2025).
In Problem Area, select "Quality of Life."
In Problem, select one that you think might relate to homelessness. The available options include: Bike/Roller/Skate Chronic, Disorderly Youth, Drinking, Drug Activity, Encampment, Graffiti, Illegal Fireworks, Non-Emergency Police Matter, Panhandling, Posting Advertisement, Squeegee, Urinating in Public.
Explore the map. How does this view compare to the "Homeless" category? What is similar? What is different? What does it mean that these categories exist separately?
When a Service Request is closed by a City Agency, a survey is sent to the person who filed it measuring how satisfied they are with how the agency handled it.
What does satisfaction look like across different problem types? Across boroughs? What might a low score reveal about how agencies respond to homelessness-related calls?
Created by the NY State Comptroller's Office. Draws from the NYC 311 dataset to include neighborhood-level insights on monthly requests by complaint type.
What patterns do you notice at the neighborhood level? Which neighborhoods generate the most homelessness-related requests — and what might explain that?
HOME-STAT (Homeless Outreach & Mobile Engagement Street Action Teams) reports daily on 311 requests for outreach assistance for people who may be homeless and living on the streets or in other public places. Note that multiple requests could be made about one person.
How does this specialized dashboard differ from the general 311 portal? What does it reveal — and what does it hide? Who is the intended audience for this data?
The NYPD and the Mayor's Office announced a citywide public safety initiative focused on addressing everyday issues that impact New Yorkers' sense of safety and well-being. The Quality of Life Division unites specially-trained officers — including neighborhood coordination officers, youth coordination officers, and traffic safety officers — into a citywide effort to tackle persistent quality-of-life concerns.
Non-emergency 311 concerns, such as noise complaints, illegal parking, homelessness-related issues, outdoor drug use, and aggressive panhandling have risen steadily across the five boroughs over the last six years and are the focus of this division.

Widening the analysis of the policing of marginality beyond the police and politicians to encompass the residents and businesses who directly instigate the policing of the poor exposes the inherent yet underappreciated tension between the insecurity of the housed and insecurity of the unhoused."
"Those with access to private property who feel threatened by those without it are able to call on the police to remove them, which in turn directly increases the insecurity of the unhoused, whose survival is disrupted by criminalization." (p. 795)
