Based on a lot of reading, Over the Next 20 years the vast majority of Urban areas are to be populated by a lot of millenials and a lot of the aging baby boomer population. (which works great because the two generations actually really thrive off of one another (Gen Y in the middle often doesn't get along with the two).Is there really demand for assisted living downtown? (serious question)
Baby Boomers are known for wanting to stay active and with it and not end up in Nursing Homes, something living in suburbia just can't offer them.
