Note: Data on expenses include central administrative offices and other enterprise support locations such as warehouses, previously known as auxiliaries. Consequently, data presented here on sample-based payroll may not match payroll presented in other economic census reports. Table excludes Notaries (NAICS 54112), Landscape architectural services (NAICS 54132) and Veterinary services (NAICS 54194), all out of scope of the survey.
