  • 1.2 This list is intended to standardize the way industry classifications are described in datasets to enable data interoperability and improve data quality.
  • 1.3 The numbering system is a six-digit code, of which the first five digits are used to describe the NAICS level used by the three countries to produce comparable data.
    • 1.3.1 The first two digits designate the sector.
    • 1.3.2 The third digit designates the subsector.
    • 1.3.3 The fourth digit designates the industry group.
    • 1.3.4 The fifth digit designates the industry.
    • 1.3.5 The sixth digit designates national industries.
      • A zero as the sixth digit indicates that there is no further national detail.
