Build a custom audience segment from demographic filters, then count how many matching people live in each geography. Use the canonical Motionworks segment catalog when an off-the-shelf cohort is good enough.
Audiences are defined as Boolean expressions over segments. Popcast supplies population counts at the block-group level. Basecast supplies the behavioral and consumer segment overlays. The Audiences application fuses the two, applies your operator logic, and returns a sized audience object.
Every sizing call includes a provenance block plus a composition block with the segment-level breakdown that produced the audience.
What you get
A reusable cohort definition keyed to your org's Popcast segment library.
At-home population counts per geography for that cohort.
Access to the canonical Motionworks audience segment catalog.
When to use this Job
