Method and limitations

  • Guests gave their home ZIP code (self-reported); no names or contact details were collected. A check-in is a response, not a unique person, so a guest at several events counts at each.
  • ZIP capture rate = usable ZIP records ÷ actual attendance × 100. Usable records are recognized U.S. ZIP codes plus Canadian and international postal codes.
  • Areas use each ZIP code’s primary county (GeoNames), so a ZIP code that crosses county lines counts in one county, and ZIP codes don’t follow city limits. Distances are straight lines between ZIP-code centers, not travel distance.
  • Visitors for this grant: guests from outside Richland County, SC or 50+ miles away. Records without a measurable distance (Canadian, international, or at an event without a venue) are left out of that share.
  • Overnight answers are self-reported by groups at the door; 5+ nights and 3+ rooms count as 5 and 3, so room nights are a minimum. Partner room nights are pickups the properties reported, kept apart from guests’ answers.
  • Projected Room nights for all groups: 1,383 attendance × 41% from outside the venue’s county ÷ 2.5 per group ≈ 230 visiting groups; × 25% staying overnight × 2.1 room nights each. Assumes the groups asked are like the rest. It is the only projected figure.
  • Labels: Verified counted or recorded directly · Self-reported stated by guests or partners, not checked · Estimated approximate, such as ZIP-center distances or an estimated count · Projected scaled up from the answers, with its method · Incomplete an input is missing, such as attendance or a venue.
