A Caveat About Bed Bug Statistics

Bed bug statistics and analysis. Bed bugs are not a reportable pest. Therefore, they are not like crime or unemployment. There are few entities collecting and analyzing data and what is available is decidedly fragmented, so that any conclusions derived should be tentative and, more important, require an understanding of context and collection mechanisms (for example:reports vs complaints, complaints vs inspections completed vs violations, private residential vspublic housing, etc.).
