US1.GIS Project Start-up View
The VDA Desktop GIS default start-up view is shown below. Click link for larger view (expand browser window for best view). This view shows patterns of population change by county for the period 2010 to 2019. Color patterns in the legend at left of map show counties gaining and losing population and why the change occurred (migration vs natural increase). See more about examining county population trends (http://proximityone.com/countytrends2019.htm).
