if my home cbg is A, then I go the the cbg B and later to cbg C, in visit destination array of C, which origin is considered: A or B?
@Fabio_VANNI The home CBG would be A
If you look at the documentation for the home_cbg here: Places | SafeGraph Docs
you can see that:
We determine the home census block group by analyzing 6 weeks of data during nighttime hours (between 6 pm and 7 am). We require a sufficient amount of evidence (total data points and distinct days) to assign a home (common nighttime) location for the device.
Thus the movemnet between A to B would not change the home CBG of the record .
Let me know if you have any more questions.
