  "name": "Nielsen DMA",
  "locale": "en-US",
  "targetingFields": ["geo_metros", "geo_metros_exclude"],
  "entries": [
    { "code": "532", "name": "Albany-Schenectady-Troy" },

For campaign display, request fields=geo_metro_names on list_campaigns or get_campaign; included labels return in geo_metro_names, excluded labels return in geo_metro_names_exclude, and both are derived from the same local table.
