Not a bad idea, but you&#x27;d have to adjust for age.  There are <i>tons</i> of joggers around every college campus, for example, but those tend not to be great places for anyone else to live.  Measuring at different times of day might be interesting too.  As a runner (not jogger) myself, I do notice that there are very different kinds of people running at different times.  The older folks tend to go out in the morning, while the late-afternoon crowds are distinctly young looking.  Lunch-break and off-hour crowds are both in between.  Which of these says what about home values or general desirability?  I don&#x27;t know, but it would be interesting to see the results.
