I think this really is a demographic issue. Because in central Illinois where I spent most of my life, I knew and saw a lot of obese and even morbidly obese people of all ages (at least in the last couple decades, as obesity has become much more common). In Illinois, I suspect that elderly obese were less active and less mobile and therefore less visible. At least the elderly obese that I came in contact with (through working in social services).
However, moving to Wisconsin, I see a lot more obese and morbidly obese. According to obesity stats, Illinois has a 21% obesity rate, while Wisconsin has 22%, so I really shouldn't be able to notice that much of difference, but there is a HUGE difference, and largely it seems to be an attitude difference. On one hand, it seems to be more acceptable to be obese. Maybe not so good, but maybe not so bad, because it's not assumed that obesity means bad-health and inactivity. There are far more active obese here, and for that matter there are far more active people of all ages and sizes including the fat elderly.
In fact, there are so many fat, active elderly in our area that I really do suspect that the activity component really may be a bigger component of longevity, mobility and health than obesity alone. I also find that there is a greater emphasis on "good" food. I'm not saying that fast food and junk food aren't as prevalent here as anywhere else, but the availability and demand for healthy, fresh, local meat, dairy, eggs, fruits and vegetables beats anywhere I've lived in Illinois.
