Analysis of Calls per Zip Code

Atlanta’s 211 service reaches out to several counties and zip codes in the state of Georgia. In order to analyze its outreach in Georgia zip codes, we analyzed the call volume for January 2015 – May 2015 for each zip code. The call volume for the top 15 zip codes is graphed below.

Zip Code


We plan on using D3 to design an interactive visualization of the number of types of call per zip code. For example, someone will be able to see how many people call for bill assistance in the 30349 zip code.


By analyzing call volume per zip code, we can also analyze why certain zip codes have fewer calls than others. The reason could be as simple as population differences. However, it could also be a lack of awareness of 211. Therefore, we will use this analysis to recommend potential advertisement efforts.
