It’s back-to-school season once again, so what better time to take a look at the population of children across the metro area? The maps that follow offer insight into which counties and Census tracts have the most children and provide clues about social conditions these kids might experience.

The mapping application below shows the percent of residents ages 5 to 19 at the county level and the Census tract level. You can use the swipe tool to view more or less tract-level data. You can also turn on elementary, middle or high schools using the layer selector tool in the top-right box.

The map shows that Forsyth County has the highest percentage of school-aged children, with about 25 percent of its population between the ages of 5 and 19. The greatest share of children is between ages 10 and 14. The Census tract with the highest percent of school-age children is Fulton County tract number 10.02, around the Georgia Tech campus (predictably, almost 100 percent of this population falls in the ages 15 to 19 bracket). Click on any geography of interest to learn more about the percent of children in the area.

The next mapping application shows the percent of children — including those younger than school age — being raised by a grandparent, and it functions the same as the application above. Generally, only a small share of children are being raised by their grandparent, with Bartow county seeing the highest rate, at 7.1 percent. At the tract level, however, there are small areas where you see much higher shares of children being raised by a grandparent. In DeKalb County’s tract number 236.02, an estimated 47.7% of children are being raised by a grandparent.

Previously, we took a look at data around childhood poverty, which showed its on the rise. The first map explorer below shows the rate of residents under age 18 (this includes children younger than school age) living in poverty at both the county and Census tract level. At the county level, Spalding County sees the most residents age 18 and younger living in poverty, at 33.7 percent. Spalding comes in second to Clayton for the highest rate of residents living in poverty overall. The data gets more sobering at the tract level: The top-ranked tract for childhood poverty is Fulton County’s Census tract 78.08, near Atlanta’s western border, which has an estimated 95.5 percent of children living in poverty.

The application below brings together all the data from the maps above. You can turn layers on and off, and you can turn the swipe bar back on by clicking the square icon in the top-left of the map viewing area. Just make sure you have two layers turned on; the app will always swipe the top-most layer.
