 | | The NAICS revision is much broadermany more industries are identified under the new system, and they are organized on the basis of their production activities (supply) alone, as opposed to the mixture of supply and demand characteristics used to classify industries under the SIC. |
 | | Industrial classification systems provide the structure for collecting and aggregating economic data, as well as for analyzing, presenting, and disseminating such data. |
 | | Newly developed industries in information services, health care provision, and even high-tech manufacturing cannot be adequately studied under the current SIC system because they are not separately identified at the most basic level of aggregation, the industry level. |
