Assisted Living in the United States: Key Statistics and Data

Assisted living is one of the largest and fastest-growing segments of the American long-term care system, serving close to a million older adults on any given day. The numbers behind the industry — who lives there, what it costs, how it's regulated, and where it's headed — matter enormously to families making some of the most consequential decisions of their lives. This page pulls together verified data from federal and state sources to give a clear, grounded picture of the assisted living landscape across the United States.

Definition and scope

The National Center for Health Statistics (NCHS), a division of the CDC, defines residential care communities — the federal umbrella term that includes assisted living — as licensed facilities that provide room, board, and at least one personal care service to adults who do not require skilled nursing care. In practice, "assisted living" as a brand name is a state-level construct: all 50 states license some version of it, but under roughly 30 different regulatory titles, including residential care facilities, personal care homes, and adult care homes (National Center for Assisted Living, NCAL).

The scale is substantial. According to the CDC's 2020 National Study of Long-Term Care Providers, approximately 28,900 licensed assisted living and similar residential care communities operated in the United States, serving roughly 996,100 residents. The average community housed about 33 residents, though facility size ranges dramatically — from intimate small residential care homes with fewer than 10 beds to large campus-style communities with more than 100 units.

For a broader orientation to what the term encompasses across different care models and regulatory categories, the assisted living statistics and data page offers additional context alongside the figures presented here.

How it works

Assisted living operates on a tiered service model. A resident enters with a baseline assessment of activities of daily living (ADLs) — bathing, dressing, eating, mobility, continence, and toileting — and receives a care plan calibrated to those needs. Staffing is driven by state regulations, not a single federal standard, because the Centers for Medicare & Medicaid Services (CMS) does not govern assisted living the way it governs skilled nursing facilities.

What that means in practice: staffing ratios, required training hours, and documentation standards vary state by state. California's Community Care Licensing Division, for instance, sets different aide-to-resident ratios than Florida's Agency for Health Care Administration. The absence of a federal floor is one of the defining structural features of the assisted living sector — and one of the central concerns in the regulatory context for assisted living.

Financially, the median national cost for assisted living reached $5,350 per month as of Genworth Financial's 2023 Cost of Care Survey, translating to approximately $64,200 annually. Costs vary sharply by geography: the national median masks state figures that range from roughly $3,500 per month in lower-cost states to more than $7,000 in high-cost markets like Massachusetts and Alaska.

Payment is predominantly private pay. Medicaid covers assisted living through waiver programs in 47 states and the District of Columbia, but benefits are means-tested and access is constrained by waitlists that, in some states, run into the tens of thousands of names (MACPAC, Medicaid and Long-Term Services and Supports).

Common scenarios

Three admission patterns account for the majority of assisted living placements:

  1. Transition from home after a health event. A fall, hospitalization, or new diagnosis — most commonly stroke, heart failure, or a hip fracture — prompts a family to reconsider whether a parent can safely live alone. This is the single most common pathway.
  2. Gradual functional decline. A family member or home health aide reports that the older adult is no longer managing medications reliably, skipping meals, or having difficulty with personal hygiene. No single precipitating event, but an accumulating pattern. Families often find signs a loved one needs assisted living helpful for recognizing this trajectory before a crisis forces the decision.
  3. Caregiver burnout. A spouse or adult child who has been providing informal care reaches a sustainable limit. This scenario is underreported in epidemiological literature but is a primary driver of placement decisions in practice.

The CDC's 2020 provider study found that 40.8% of residential care residents had Alzheimer's disease or other dementias — a figure that underscores why memory care services, whether offered within a standard community or in a dedicated unit, are not a niche add-on but a core operational requirement for most facilities.

Decision boundaries

Assisted living sits between independent living and skilled nursing on the care continuum, and both transitions carry distinct thresholds.

Assisted living vs. independent living: Independent living communities provide housing and amenities but not personal care services. The moment a resident requires hands-on assistance with two or more ADLs on a daily basis, assisted living becomes the appropriate classification.

Assisted living vs. skilled nursing: Federal and state regulations define skilled nursing as care requiring a licensed nurse — wound care, IV therapy, ventilator management. When an assisted living resident's medical needs cross that line consistently, continued placement in assisted living may violate state licensing requirements and trigger a mandatory discharge. The when assisted living is not enough page addresses how facilities and families navigate that transition.

Assisted living vs. memory care: Dedicated memory care units operate under enhanced staffing and physical environment standards — secured perimeters, cognitively appropriate programming, specialized staff training. A resident with moderate-to-advanced dementia who demonstrates elopement risk or significant behavioral symptoms typically requires memory care rather than standard assisted living. The distinction matters clinically and financially; memory care commands a national median premium of approximately $1,000 per month above standard assisted living rates (Genworth, 2023).

Quality oversight sits primarily with state licensing agencies, with voluntary accreditation available through bodies including the Commission on Accreditation of Rehabilitation Facilities (CARF) and the Joint Commission. Neither accreditation is required for operation, which is why state inspection records remain the most reliable public-facing indicator of facility performance.
