Quantifying and understanding the scope of a community’s potential market and competition are important tools for ensuring viability. However, assisted living models have shifted in response to economic conditions, market behaviors, older adults’ desires and other factors. Many markets are experiencing the emergence of smaller memory “board and care” homes that are changing the business landscape, along with increased interest in community-based services and technologies. As a result, data collection, analysis and how markets are quantified are shifting. This session will discuss analyzing and quantifying the competition, identify challenges in segmenting the market for levels of care, and review current methodological approaches to quantifying the depth of the markets.
