The Point-in-Time count is a single-night tally, conducted every January, of people experiencing homelessness across the United States. The Department of Housing and Urban Development requires local planning bodies to carry out the count in their areas and report the results, which HUD then compiles into the Annual Homeless Assessment Report delivered to Congress each year.1HUD USER. AHAR Reports The resulting figures shape federal funding decisions and serve as the country’s standardized measure of homelessness, though the methodology has real limits worth understanding before relying on the numbers.
Who Gets Counted
The count uses the federal definition of homelessness from the McKinney-Vento Homeless Assistance Act. Only people who are “literally homeless” on the count night are included in the data submitted to HUD. That means someone who lacks a fixed, regular, and adequate nighttime residence, or whose primary nighttime residence is a place not meant for sleeping, such as a car, park, abandoned building, or bus station.2Office of the Law Revision Counsel. 42 USC 11302 – General Definition of Homeless Individual People in emergency shelters, transitional housing, or hotels and motels paid for through government or charitable programs also qualify.
The data splits into two categories. Sheltered homelessness covers people sleeping in emergency shelters and transitional housing on the designated night. Unsheltered homelessness covers people found in places not designed for regular sleeping, including parks, vehicles, encampments, and abandoned structures.3eCFR. 24 CFR 578.7 – Responsibilities of the Continuum of Care
Who Is Excluded
Several groups fall outside the count even though they lack stable housing. People “doubled up” with friends or family because they cannot afford their own place are not included in the data submitted to HUD. Neither are people in jails, hospitals, or other institutions on the count night, even when they have nowhere to go on release. Some local agencies count these populations for their own planning, but HUD does not accept that data in the official tally.4HUD Exchange.

Who Runs the Count
HUD does not send federal workers into the field. The McKinney-Vento Act authorizes HUD to require Continuums of Care to conduct the count within their geographic areas.5HUD Exchange. Point-in-Time Count Standards and Methodologies – Section: CoC Responsibility for Conducting PIT Counts A Continuum of Care, or CoC, is a local or regional planning body that coordinates homeless services. Roughly 400 CoCs cover the country, ranging from single counties to multi-county regions and major cities.
Each CoC picks a lead agency to organize the work: dividing territory into survey zones, recruiting and training volunteers, coordinating with shelter providers, and compiling the results. The CoC is also responsible for preventing double-counting across overlapping service areas. Communities receiving Emergency Solutions Grants funding must participate as a condition of that funding.6HUD Exchange. Point-in-Time Count and Housing Inventory Count
When the Count Happens
Federal standards require the count to take place during the last ten calendar days of January.7HUD Exchange. PIT Count Standards Both the sheltered and unsheltered portions must represent a single night within that window.
Frequency depends on the population. CoCs must count the sheltered population every year. The unsheltered count is required at least every other year, and HUD typically calls for it during odd-numbered years.3eCFR. 24 CFR 578.7 – Responsibilities of the Continuum of Care Many CoCs voluntarily conduct the unsheltered count annually for consistency, but biennial is the federal floor.
When extreme weather or a natural disaster threatens the count’s safety or accuracy, a CoC can request an exception. The request goes to HUD by email with an explanation and a proposed alternative date. HUD generally approves exceptions for severe weather, disasters, or a community’s longstanding tradition of counting between December 1 and March 31, and approved counts typically move to the last ten days of February.8U.S. Department of Housing and Urban Development.

How the Count Is Conducted
Sheltered and unsheltered counts use different methods because one population is already connected to the service system and the other is not.
Sheltered Count
CoCs have three options for counting people in shelters: pulling data from the Homeless Management Information System (HMIS), conducting in-person surveys at shelters, or combining both.9HUD Exchange. Section 4 – Implementing the Sheltered PIT Count HMIS is the electronic database where shelter providers record occupancy and client information, so in communities with strong data systems the sheltered count can be generated largely from existing records. Domestic violence shelters and other victim service providers cannot enter client data into HMIS and instead submit aggregate, de-identified numbers through a comparable database.
Unsheltered Count
The unsheltered count is the harder part. Volunteers and outreach workers spread out across assigned zones on the designated night, looking for people sleeping in parks, under bridges, in vehicles, and in other locations not meant for habitation. Some communities supplement the nighttime street count with service-based surveys in the following days, asking people at soup kitchens, drop-in centers, or health clinics where they slept on the count night.
A full census is not always feasible in large or geographically complex jurisdictions. HUD permits statistical sampling: dividing the area into subareas, categorizing each by expected density, counting “certainty subareas” where concentrations are highest, randomly selecting additional areas to survey, and then weighting the results to estimate the total.10HUD Exchange. How to Use Sampling within a CoC to Conduct an Unsheltered PIT Count Sampling makes the count possible in sprawling rural regions but introduces estimation error.
Answering a PIT survey is voluntary. Many CoCs offer incentives such as gift cards, warm clothing, or hygiene items to encourage people to stop and respond, funded through a mix of HUD grants, state and local money, and private donations.11U.S. Government Accountability Office. Homelessness – HUD Should Help Communities Better Leverage Data to Estimate Homelessness (Report GAO-22-104445)
What Data Is Collected
The count is not just a headcount. HUD requires demographic information for every person identified, including age, gender, race, and ethnicity. These details let the federal government track disparities in who experiences homelessness and target funding accordingly.
CoCs must also report on specific subpopulations that HUD tracks for targeted federal programs:8U.S. Department of Housing and Urban Development. Notice for HIC and PIT Count Data Collection for CoC Program and ESG Program (Notice CPD-2023-11)
- Veterans, including total veteran households and demographics.
- Unaccompanied youth under 25 without a parent or guardian, covering both young adults ages 18 to 24 and unaccompanied children under 18.12HUD USER. 2024 Annual Homelessness Assessment Report (AHAR) to Congress – Part 1
- Parenting youth under 25 who are parents or guardians of children present with them, with no one over 24 in the household.
- Chronically homeless individuals, defined as people with a disability who have been homeless for at least 12 continuous months or on at least four separate occasions totaling 12 months over the past three years.13HUD Exchange. Definition of Chronic Homelessness
- Adults with serious mental illness, substance use disorder, or HIV/AIDS.
- Survivors of domestic violence. Reporting on this group is optional, but HUD encourages it.
Privacy During the Survey
PIT surveys do not require names, Social Security numbers, or dates of birth. Many CoCs collect only initials for de-duplication. HUD’s standards require surveys to be administered in ways that protect participant privacy and safety, and everyone involved in the count, including volunteers, must receive training on data collection and privacy protocols.7HUD Exchange. PIT Count Standards
Extra precautions apply when surveying survivors of domestic violence, dating violence, sexual assault, or stalking. HUD’s standardized question asks whether the person is experiencing homelessness because they are fleeing such violence. Some CoCs use numbered response cards for sensitive questions so the respondent never has to say the answer aloud. Surveys should be conducted out of earshot of others, never in the presence of a partner or spouse, and if a surveyor determines the situation is unsafe, they note the concern and move on.14HUD Exchange.

From Local Data to the Report to Congress
After the count, CoCs submit their data through HUD’s Homelessness Data Exchange 2.0 (HDX 2.0), the online portal that connects local agencies to the federal government.15HUD Homelessness Data Exchange 2.0. 2025 Housing Inventory Count and Point-in-Time Count of People Experiencing Homelessness – Data Submission Guidance CoCs typically have several months after the January count to clean and validate their data before the submission window closes.
Meeting the deadline matters for funding. HUD has generally treated timely submission as a factor in the annual CoC Program Competition, which determines grant allocations for homeless services nationwide, and communities that demonstrate reductions in their homeless populations over time earn higher scores.16HUD Exchange. 2026 HIC and PIT Count Data Submission Guidance HUD reviews the data for inconsistencies, then incorporates it into the Annual Homeless Assessment Report, which provides the national estimates, trend data, and subpopulation breakdowns that drive federal housing policy.1HUD USER. AHAR Reports
What the Count Does Not Measure
Anyone using PIT data should know its limits. The count is a single-night snapshot, not a measure of how many people experience homelessness over the course of a year. Someone who lost housing in February and regained it by December never appears in the January count. The annual flow of people through homelessness is substantially larger than the point-in-time figure suggests.
The exclusion of doubled-up populations is the most significant gap. Families crowded into a relative’s apartment after losing their own housing, people sleeping on a friend’s couch, and individuals paying for a motel themselves all fall outside the federal definition for PIT purposes, even though many would describe those situations as homelessness.4HUD Exchange. Differences Between Who Is Included in Sheltered and Unsheltered PIT Counts
The unsheltered count is inherently imprecise. People sleeping in hidden locations, inside vehicles with tinted windows, or in areas volunteers cannot safely access are easy to miss. Families experiencing homelessness are especially undercounted because they are less likely than single adults to be visibly unsheltered. Where statistical sampling replaces a full census, estimation error adds another layer of uncertainty. The count is the best nationally standardized measure available. It is not an exact population total, and treating it as one overstates what a single-night methodology can deliver.
