The Design & Architecture industry is organized into distinct segments that group related disciplines, professions, firms, and business activities within the larger field. Each segment represents a different way environments, products, systems, interfaces, and visual information are conceived, designed, developed, and brought into use, while also showing how creative, technical, and operational roles connect across the industry. These segments include Built Environment Design, Interior & Spatial Design, Visual Communication Design, Digital & Interactive Design, Product & Industrial Design, and Fashion & Textile Design.

Each segment is also connected to relevant North American Industry Classification System, or NAICS, codes. NAICS is the standard system used by federal statistical agencies to classify businesses and economic activity by industry. Because Design & Architecture includes overlapping disciplines and professionals who may work across firms, freelance practices, in house teams, manufacturing, development, media, and other sectors, no single NAICS code captures the full scope of the industry. The codes identified here provide the closest available classifications for understanding where these activities appear within existing economic data.

Breaking the industry into segments, disciplines, and corresponding NAICS classifications creates a clearer framework for understanding how Design & Architecture functions as an economic sector. It also makes it possible to identify shared and segment specific needs, examine workforce and business conditions, and better understand the economic and cultural role of each area in greater detail.
