SERVICES, NOT ELSEWHERE CLASSIFIED (SIC MAJOR GROUP 89) Establishments primarily providing services, not elsewhere classified, such as artists (excluding commercial and medical artists), authors, scientific consultants (working on their own account), inventors, lecturers, music arrangers, newspaper columnists, radio commentators, song writers, weather forecasters, and writers. There is evidence that among small employer establishments (for which kind-of-business information is obtained from administrative records), many service establishments are classified incorrectly in this industry because there is insufficient information to determine the correct kind-of-business classification. Therefore, the published data probably overstate the number of establishments and level of activity for this category.
