This animation depicts City of Austin building permit data from January 1990 through September 2009. Each second of the animation represents one month of time. So, 0:01 is January 1990, 0:13 is January 1991, and so on. Dark green dots represent new residential construction, light green dots residential remodels, yellow dots are non-residential new construction, orange dots are non-residential remodels, and red dots are demolitions. Watch full screen in HD for the best effect.
