The senior living industry is in the middle of a sponsorship transition crisis that most operators are not talking about publicly.
According to Ziegler's 2025 midpoint update, more than 1,100 nonprofit, market rate senior living communities have changed hands since 2015. Transaction volume is at record levels, with 784 transactions tracked in 2025, up from 740 in 2024 and 640 in 2023. The activity is being driven by workforce challenges, CEO turnover, and expense pressures that have only intensified since the pandemic.
But the most consequential finding is not the volume of activity. It is where the communities end up.
The Argument
The nonprofit senior living sector is contracting through attrition while affiliation activity hits record levels. The two trends are connected. Without shared data infrastructure, transparent benchmarking, and direct access to the innovation ecosystem, affiliation produces coordination at best, not transformation.
The 75% problem
Ziegler reports that only about one quarter of nonprofit communities in transition transfer to another nonprofit sponsor. The other three quarters leave the nonprofit sector entirely. Nearly 48% of all nonprofit transitions since 2015 have been acquisitions by private sector buyers.
Meanwhile, closure rates among nonprofit operators going through sponsorship transition have climbed sharply. Between 2015 and 2025, 15.1% of operators that experienced a change in sponsorship ended up closing. Between 2020 and 2025 alone, that figure rose to 19.8%.
The implications are significant. The nonprofit senior living sector is contracting through attrition while affiliation activity hits record levels. The two trends are connected.
By the numbers:
75% of nonprofit communities in transition leave the nonprofit sector entirely
48% of all nonprofit transitions since 2015 have been acquisitions by private sector buyers
19.8% closure rate for nonprofit operators undergoing sponsorship transition between 2020 and 2025
Why affiliations underperform
The core issue is information asymmetry. Communities pursue affiliation expecting access to best practices, shared infrastructure, group purchasing power, and technology platforms they cannot build alone. The promise is real. The execution is often not.
Without standardized data systems connecting affiliated communities, the benefits remain theoretical. Operators cannot benchmark what they cannot measure. Best practices cannot transfer between communities that lack a common operational language. Technology platforms get adopted unevenly, creating new fragmentation instead of solving the old kind.
The result is an industry where affiliation activity is high but affiliation impact is uneven. Communities sign on expecting transformation and often receive coordination at best. When affiliations underperform, communities run out of options. Sponsorship transitions accelerate. Closure rates climb. The sector loses capacity.
What innovation forward operators do differently
The affiliated communities that actually deliver on the promise share three characteristics.
First, they invest in interoperable technology that feeds a common data layer across the network. Without shared data infrastructure, there is no shared learning.
Second, they participate in structured peer benchmarking with transparent outcomes. Without visibility into how peer communities are performing, there is no meaningful improvement loop.
Third, they maintain direct relationships with the research and AgeTech ecosystems that drive innovation, rather than waiting for innovation to arrive through the affiliation alone.
ISF was designed to address each of these structural gaps. The ISAI data platform connects every ISF community to a common data infrastructure. The research partnerships with Stanford, NIH, and Cedars-Sinai give affiliated communities direct exposure to academic innovation. The AgeTech incubation program provides early access to technologies that haven't yet reached the broader market.
The path forward
The Ziegler data tells a clear story. Affiliation activity is at record levels. Nonprofit attrition is accelerating. The structural problem is real.
The next generation of senior living networks will be defined by data driven collaboration, shared innovation infrastructure, and transparent outcome measurement.
That is the model ISF is building.
