How do you match the job postings to Industries?
The Employers are matched to NAICS codes to obtain their Industry.
The NAICS codes are assigned when matching the poster to the DUN & Bradstreet database. Due to the lack of contact information found on many ads, we match approximately 60% of the postings to a D&B record. Of ads that have company names, 80% of the volume is match to a DUNs number. Therefore the Industry totals are a subset of the total data..
