DATA TABLE
A Quick Caveat!
The majority of the 200+ variables associated with this map come from the American Community Survey, which is a sample-based data product with margins of error associated with it. Many of Georgia’s cities are quite small, and the smaller the city, the larger the margin of error will be.
For simplicity sake, we did not map the margins of error. So please keep this in mind when getting data for your city, especially if it is small (less than 5,000 population).
Quick Tip #1!

When moving the mouse over the map, you can see individual city values for the variable being mapped in the legend. It is also highlighted on the scatter plot so you can see where your city (Snellville) falls on two different dimensions (bachelor’s + & income) and get an instant comparison to all other cities in Georgia.
