Understanding disability rates and how they affect housing market behavior, in particular moves to supportive housing or assisted living, is a very difficult thing to do. Statistics Canada tells us that 43% of the 65+ population in Canada have some degree of disability, primarily mobility, agility, pain, or hearing. Of those with disabilities, 60% are mildly or moderately disabled, while 40% have severe or very severe disabilities. What “mild”, “moderate”, and “severe” mean is not easy to define. Statistics Canada uses a complicated rating system to categorize disabilities. At any rate, the question is how these disability rates affect housing market behavior.
To establish a context for his discussion, it’s useful to reflect on the fact that the huge majority of houses in Canada are neither “visitable” nor “accessible”, meaning they do not accommodate aging in place. So does this mean that when people become disabled in some way will they move to supportive housing? Maybe not all people, or even a majority of people, but some quantifiable proportion? Alas, no. We know that entrance into service-enriched housing such as supportive housing or assisted living is primarily need-driven, which means that people move into these types of environments not because they want to but because they have to. However that does not necessarily imply the presence of a disability—people may move because their spouse died and they are afraid to stay alone, or because they are isolated, or not eating properly, or because they have lost their driver’s license. And couples with disabilities are much less likely to move to supportive housing than individuals because they are able to help each other. If there were some way to quantify demand based on disability status we would have to adjust for the number of couples in a market area, which would further complicate an already suspect analysis.
As a result of all these confounding variables, in my view it is not possible to arrive at any conclusions at all about the demand for service-enriched housing in a community by applying national disability rates to the seniors’ population and assuming that some arbitrary proportion of that group will choose to move to service-enriched housing. Some market analysts do this I am sad to report. Be careful if you are working with one.

Many people (myself included) share the view that disability rates among the seniors’ population have been declining. For example, here’s a headline from a National Association of Aging document dated May, 2001: Dramatic Decline in Disability Continues for Older Americans. And what’s the evidence? Between 1994 and 1999, the percentage of Americans over the age of 65 with disabilities declined by 2.6% per year.
In answer to the obvious question: “why”?, the article suggests several possible reasons—improvements in maternal health early in the 20th Century; better control of infectious childhood diseases; behavioural changes such as declines in the incidence of smoking; better management of diseases such as hypertension; better drugs; and even increases in education levels.
But a recent article in Public Policy and Aging Report suggests that declines in disability rates are due not to medical science, but to “disability-friendly” environmental changes including curb cuts, disabled access ramps and elevators, and transportation services. Improvements in assistive devices (walkers, wheelchairs, scooters) have also enabled people with mobility impairments to get around better on their own.
The Public Policy and Aging Report article is focused mostly on physical impairments that impede a person’s ability to interact with the built and social environment but it also refers briefly to the positive impact of higher education levels on rates of cognitive impairment.
It is interesting to think about this. Disability is not defined as an impairment per se, but as a “social construct insofar as it reflects the ease or difficulty that individuals with physical impairments experience interacting with the built and social environment.”
