Each track has a demographic profile
A demographic profile can probabilistically
assigned to each track, based primarily on the neighborhood in which
the device started its day. For example, one might start with the
assumption that a device that began its day in a neighborhood that
is 70% upper income Caucasian has a 70% chance of belonging to an
upper income Caucasian.
With this operating premise, one can determine the sociodemographic profile of, say, the people passing a given location.
