Largest PIT CoCs Do Not Always Print the Tightest Rental Vacancy

Homelessness policy debates often collapse two different housing facts into one slogan: the places with the most people counted outdoors must also have the tightest rental markets. Continuum of Care (CoC) Point-in-Time (PIT) counts and Census Housing Vacancy Survey (HVS) rental vacancy rates are the two series that desks reach for when that claim shows up in hearings. They do not always move together. This cut asks a narrower question. Among the Continuums with the largest January 2025 PIT totals, do the biggest counts sit in the jurisdictions that also print the lowest rental vacancy rates? The interactive dashboard pairs HUD CoC PIT totals with each Continuum's primary-state HVS rental vacancy rate — the disclosed annual series available for every state — and layers national vacancy trend and HUD Picture of Subsidized Households framing for the assisted stock that sits between empty units and the street count. ## What the January 2025 PIT actually shows HUD's 2025 Annual Homelessness Assessment Report (AHAR) Part 1 places the national PIT near 745,652 people on a single January night. Roughly half of that population lives in Continuums that contain one of the fifty largest U.S. cities. Absolute scale is brutally uneven. New York City alone reports 125,683 people — about one in six of the national total. Los Angeles City & County reports 67,777. After those two megacontinuums, the ladder drops into the mid-teens of thousands: Seattle/King County (16,936), Metropolitan Denver (10,774), San Jose/Santa Clara (10,711), and Portland/Multnomah (10,526). Seventeen urban or suburban Continuums still clear 5,000 people. That concentration matters politically because federal CoC grants, local shelter capacity, and mayoral accountability all track counts, not per-capita rates. A Continuum can look "smaller" on a rate basis and still dominate the national ledger in people. ## How rental vacancy enters the frame Census HVS rental vacancy is the share of rental units that are vacant and available. Nationally, the quarterly series (FRED RRVRUSQ156N) climbed from the mid-5% range in 2022 into the mid-7% range by early 2026 — a clear loosening of the national rental market after the pandemic squeeze. State annual rates for 2025 still span a wide band: Massachusetts prints 3.4%, California 4.8%, New York 5.3%, Washington 6.6%, Arizona 8.4%, Florida 10.2%, and Texas 11.0%. That dispersion is the analytical hinge. If the largest PIT Continuums simply lived inside the tightest vacancy states, the scatter would slope down and to the left: bigger counts, lower vacancy. The panel does not draw that neat line. ## The discordant ranks: size is not tightness New York City owns the PIT crown, yet New York state's HVS rental vacancy (5.3%) sits in the middle of the large-CoC pack — looser than Massachusetts or California, tighter than Florida or Texas. Boston's Continuum is an order of magnitude smaller than New York's (5,540 versus 125,683) while Massachusetts prints the tightest vacancy among states that host a top-panel Continuum (3.4%). California hosts a stack of high-PIT Continuums — Los Angeles, San Jose, San Diego, Oakland, San Francisco, Orange County, Sacramento, Fresno, Stockton — against a 4.8% state vacancy that is tight by national standards but not uniquely paired with any single Continuum's size. At the other end, Houston and Austin sit near 3,300 people in the PIT panel while Texas vacancy runs near 11%. Phoenix clears almost 10,000 people with Arizona vacancy at 8.4%. Honolulu prints a mid-panel PIT (4,920) against Hawaii's 8.7% vacancy. Large absolute homelessness and loose statewide rental markets can coexist; so can modest Continuum counts and extremely tight statewide vacancy. | CoC (short) | PIT (Jan 2025) | Home-state vacancy % | PIT / vacancy point | | --- | ---: | ---: | ---: | | New York City | 125,683 | 5.3 | 23,714 | | Los Angeles | 67,777 | 4.8 | 14,120 | | Seattle | 16,936 | 6.6 | 2,566 | | Denver | 10,774 | 5.8 | 1,858 | | San Jose | 10,711 | 4.8 | 2,231 | | Boston | 5,540 | 3.4 | 1,629 | | Miami | 3,615 | 10.2 | 354 | | Houston | 3,325 | 11.0 | 302 | The PIT per vacancy point ratio is a desk shorthand, not a causal model. It simply shows how many counted people sit behind each percentage point of home-state vacancy. New York and Los Angeles dominate that ratio because their numerators are enormous, not because their vacancy readings are the lowest on the table. ## California's stack versus the Sun Belt's slack Filter the dashboard to the West and the pattern sharpens. California Continuums occupy much of the upper PIT ladder while sharing the same 4.8% state vacancy proxy. That is a political geography story as much as a housing-market story: multiple large Continuums inherit the same statewide vacancy reading even though Bay Area, Southern California, and Central Valley rental markets differ on the ground. The HVS state series cannot resolve those intra-state gaps; it can only show that California's large Continuums operate inside a relatively tight statewide envelope compared with Texas or Florida. Sun Belt Continuums in the panel — Miami, Houston, Austin, and to a lesser extent Phoenix and Las Vegas — combine lower absolute PIT totals with looser vacancy. That does not prove that empty apartments absorb street homelessness. It does undercut the slogan that every large PIT Continuum is simultaneously living through a historically tight rental market. Some of the largest counts sit in tight states; some of the loosest vacancy readings sit under mid-sized Continuums. ## Shelter systems and the Picture of Subsidized Households PIT totals mix sheltered and unsheltered people. New York City shelters about 96% of its counted population; Boston about 98%. Los Angeles shelters about 35%; several other California Continuums print unsheltered majorities above 55%. Vacancy tightness and shelter policy are different dials. A Continuum can run a high sheltered share inside a middling vacancy state (New York) or a low sheltered share inside a tight vacancy state (Los Angeles). Treating vacancy alone as the homelessness explanation erases that institutional layer. HUD's Picture of Subsidized Households describes the assisted stock that sits between market vacancy and the PIT: Housing Choice Vouchers (roughly half of assisted households nationally), project-based multifamily contracts, and public housing. Vouchers only house people when private landlords accept them and when units clear inspection against payment standards — a friction that rises when vacancy is low and landlords can choose unassisted tenants. Project-based and public housing turn on unit availability and waitlists rather than market vacancy per se. The dashboard's assisted-mix panel is national framing, not invented CoC microdata: it reminds readers that federal assistance is a third market, not a residual of HVS vacancy. ## National vacancy loosened while PIT stayed historically high From 2022 through early 2026, national rental vacancy drifted upward into the 7.0–7.3% band. Over the same multi-year window, HUD PIT totals remained near record levels after the 2024 surge. The national cycle therefore weakens any claim that contemporaneous national vacancy alone explains Continuum-level PIT ranks. Local Continuum counts reflect migration into shelter systems, eviction timing, street outreach capacity, weather on count night, and one-night methodology limits — none of which appear in a quarterly vacancy percentage. The politics still bind the two series together because both feed the same hearing rooms. Mayors cite vacancy when asking for production subsidies; Continuums cite PIT when asking for emergency shelter and CoC renewals. Putting them on one scatterplot is useful precisely because the ranks disagree. ## Caveats and geography limits Several limits should stay on the page. First, CoC ≠ state. Pairing a Continuum with its primary-state HVS rate is a disclosed proxy, not a metro-matched ACS or HVS MSA table. Los Angeles and Fresno inherit the same California vacancy reading even though their rental markets differ. Second, PIT is a one-night estimate with known undercount risk for unsheltered people and sensitivity to weather and survey design. Third, vacancy is not affordability: a 7% vacancy rate can still leave extremely low-income renters with no units they can pay for. Fourth, Picture of Subsidized Households program shares here are national structure, not Continuum-level unit inventories. Fifth, correlation across twenty-four large Continuums is descriptive; it is not an identification strategy for "vacancy causes homelessness" or the reverse. ## What the desk should take away The largest Continuums do not automatically print the tightest vacancy. New York leads the count without leading tightness. California stacks multiple high-PIT Continuums inside a tight statewide vacancy envelope. Texas and Florida Continuums in the panel sit lower on absolute PIT while printing double-digit vacancy. National vacancy has loosened into the mid-7% range even as Continuum counts remain elevated. For legislative staff and city budget offices, the operational implication is blunt: production and vacancy policy, shelter capacity, and voucher utilization are related but not interchangeable levers — and Continuum size alone is a poor ranking of market tightness.
