A Census Block Group (CBG) is the most granular level the US Census Bureau reports data on, and represents a neighborhood of ~1500 people. By analyzing a large panel of anonymized GPS movement data, SafeGraph derived the popularity of a CBG and distances traveled between CBGs.
We also combined this anonymized GPS data with our dataset of 5 million Points-of-Interest (SafeGraph Places
) to determine visits to places like stores or restaurants. We used these visit counts to derive consumer insights such as top brands (ex. McDonald's) visited in each neighborhood (CBG).
