The Standard Industrial Classification (SIC) system, formerly used to categorize businesses in the United States, assigned numerical codes to different industries. Establishments providing services related to connecting employers with potential employees were generally classified under 7361 – Employment Agencies. This categorization allowed for statistical analysis of employment trends within this specific sector.
This numerical classification system facilitated data collection and analysis, enabling government agencies, researchers, and businesses to track industry growth, employment patterns, and economic performance within specific sectors. Historical data using these codes can provide valuable insights into industry trends. While the North American Industry Classification System (NAICS) has replaced the SIC system, understanding historical SIC codes remains relevant for analyzing historical data.
