IMPLAN Citation Guidelines

If you use data from any of the IMPLAN results tables, underlying regional data, or multipliers, IMPLAN should be cited as your source. Here’s how to do it.

When citing IMPLAN, please be sure to include a direct hyperlink to www.implan.com rather than plain text. This helps ensure proper attribution and easy access to IMPLAN’s resources.

These include footnotes and captions for tables and charts. When citing IMPLAN as a data source, it is mandatory that you include the Model Year or Data Year, and region of your study.

Examples:

  • Footnote: “1For more information on the IMPLAN modeling process, visit IMPLAN.com.”
  • Caption: “Source: IMPLAN 2026 Model Year for model region including Oregon’s Yamhill, Marion, Polk, Clackamas, and Multnomah counties.”
  • Parenthetical Citation: “The RPC for Oilseeds for Washington County is .75 (IMPLAN 2024 Data Year).”

3. In the Reference Section

Inserting the IMPLAN Disclaimer

The following is optional but recommended text to include in your published studies:

IMPLAN is a regional economic analysis software application that is designed to estimate the impact or ripple effect (specifically backward linkages) of a given economic activity within a specific geographic area through the implementation of its Input-Output and Social Accounting Matrix model. Studies, results, and reports that rely on IMPLAN data or applications are limited by the researcher’s assumptions concerning the subject or event being modeled. Studies such as this one are in no way endorsed or verified by IMPLAN Group LLC unless otherwise stated by a representative of IMPLAN.

IMPLAN provides the estimated Indirect and Induced Effects of the given economic activity as defined by the user’s inputs. Some Direct Effects may be estimated by IMPLAN when such information is not specified by the user. While IMPLAN is an excellent tool for its designed purposes, it is the responsibility of analysts using IMPLAN to be sure inputs are defined appropriately and to be aware of the following assumptions within any I-O and Social Accounting Matrix Model:

  • Constant returns to scale
  • No supply constraints
  • Fixed input structure
  • Industry technology assumption
  • Constant byproducts coefficients
  • The model is static
  • Backward linked
  • Time Delineated
