Custom Industry Groupings. In preparing the economic profile and economic impact estimates, aerospace establishments are classified into eight major groups and 25 subgroups as detailed in Figures 2 and 3. The industry groupings are chosen to reflect the current structure and growth trend of the aerospace industry in the Greater Oklahoma City region. The groupings are similar to the broad industry sectors defined under the NAICS industry classification system but capture far more detailed components of the aerospace sector than possible when using NAICS. 30 The groupings used in the industry profile provide a more functional and descriptive view based on a firm’s primary product line or service provided. The NAICS structure tends to obscure many of the specialized activities taking place within the broader aerospace sector. For example, governmental entities are tracked as a unique component of the industry due to the substantial presence of two large federal facilities – Tinker AFB and the FAA Center. State and local government entities are tracked separately from federal government. The largest state and local government entity is the Oklahoma Air National Guard. The industry groupings are chosen to reflect the current structure and growth trend of the aerospace industry in the Greater Oklahoma City region. The groupings are similar to the broad industry sectors defined under the NAICS industry classification system but capture far more detailed components of the aerospace sector than possible when using NAICS. The NAICS system is based on a production-oriented concept whereby establishments are group into industries according to similarity in the processes used to produce goods or services. This approach tends to obscure many of the specialized activities taking place within the broader aerospace sector. The groupings used in the 2020 industry profile provide a more functional and descriptive view based on a firm’s primary product line or service provided. Government is treated as a unique component of the industry due to the substantial presence of both Tinker AFB and the FAA Center. State and local government are tracked separately from federal government. The eight major groups in Figure A1 are used throughout the report to develop estimates of the economic contribution of the aerospace sector. The 25 detailed subgroups are used to provide more industry detail in an accompanying digital directory of aerospace and aviation firms operating in the region. In preparing the economic impact estimates, aerospace establishments are classified into eight major groups as detailed in Figure 2.
