CAGR (Compound Annual Growth Rate)

Update: D.R.E.A.M. Map was merged into "Metro Maps" after this article was published.

This is a useful measure of growth over multiple time periods. It can be thought of as the growth rate that gets you from the initial investment value to the ending investment value if you assume that the investment has been compounding over the time period.

This setting in the Metro Maps tool helps smooth-out ‘noise’ associated with small zip code level sample sizes.)
