Is there a standard reference for describing SafeGraph data?

Questions & Help

hi, could i ask if there’s a standard reference for describing SafeGraph data? SafeGraph folk, do you have a preferred way of describing your data and how it was collected? the website is understandably a bit sparse on specifics (e.g., is the location data all from GPS, or a mix of sources, etc.) and it’d be useful to be able to include this in a paper. thank you!

oh just to check, that doc says

To enhance privacy, SafeGraph excludes census block group information if fewer than five devices visited an establishment in a month from a given census block group.”

is that still applicable to the weekly patterns dataset?

i also want to link you to the May release notes because they address changes to the differential privacy rules: https://docs.safegraph.com/changelog/may-2020-release-notes
