introduction
Introduction
  • USPS Delivery Sequence File
    • Access through ADVO and other companies
    • >140 million addresses
  • Research on use as HU frame
    • O’Muircheartaigh, Iannacchione and others
    • Can increase accuracy and reduce cost compared to traditional listing
  • Commercial building frame?
design of test
Design of Test
  • 11 segments across the country
  • In-field listing of commercial buildings
    • December 2006
  • Compare to ADVO database
multiplicity
Multiplicity
  • ADVO contains addresses
    • But we are interested in buildings
  • Multiple addresses, one building
    • Office building
    • Strip mall
  • Multiple buildings, one address
    • Corporate complex
results counts
Results: Counts
  • Ratio of ADVO to listed buildings
    • Overall 90%
    • Ranged from 17% in very rural segment to 184%
  • Causes of Ratio ≠ 100%
    • Undetected multiplicities
    • Overcoverage by ADVO
    • Undercoverage by ADVO
    • Undercoverage by lister
maps segment 1
Maps: Segment 1
  • Red dots indicate listed building not on ADVO
  • ADVO has no coverage in northern half
    • Can identify such areas for us
conclusions
Conclusions
  • Findings similar those for residential addresses
    • Rural undercoverage
    • Lister error
  • Additionally: un-owned areas
  • Obvious ADVO advantage is cost
conclusions16
Conclusions
  • ADVO in all segments
  • ADVO + listing in under-covered segments
  • ADVO + reconciliation listing
    • Similar to enhanced listing
    • In sample of segments or all segments
  • Field listing
