1. Written as Part of the Text
- When referencing the application or data, spell “IMPLAN” in all caps.
- Similarly, when referencing the company, use “IMPLAN Group, LLC.”
Examples:
- “Our study used IMPLAN 2017 Data to examine regional purchase coefficients for the study area.”
- “We used the IMPLAN calculation process to estimate the economic impact of [event(s) being inputted in IMPLAN]. The following estimations and assumptions were made outside of IMPLAN to evaluate the initial or direct effect of [event(s) being inputted in IMPLAN]:”
- “We love IMPLAN Group, LLC so very, very much.”
2. In-text Citations
These include footnotes and captions for tables and charts. When citing IMPLAN as a data source, it is recommended that you include the data year and region of your study.
Examples:

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 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 Model:
- Constant returns to scale
- No supply constraints
- Fixed input structure
- Industry technology assumption
- Constant byproducts coefficients
- The model is static
By design, the following key limitations apply to Input-Output Models such as IMPLAN and should be considered by analysts using the tool:
- Feasibility: The assumption that there are no supply constraints and there is fixed input structure means that even if input resources required are scarce, IMPLAN will assume it will still only require the same portion of production value to acquire that input, unless otherwise specified by the user. The assumption of no supply constraints also applies to human resources, so there is assumed to be no constraint on the talent pool from which a business or organization can draw. Analysts should evaluate the logistical feasibility of a business outside of IMPLAN. Similarly, IMPLAN cannot determine whether a given business venture being analyzed will be financially successful.
- Backward-linked and Static model: I-O models do not account for forward linkages, nor do I-O models account for offsetting effects such as cannibalization of other existing businesses, diverting funds used for the project from other potential or existing projects, etc. It falls upon the analyst to take such possible countervailing or offsetting effects into account or to note the omission of such possible effects from the analysis.
- Like the model, prices are also static: Price changes cannot be modeled in IMPLAN directly; instead, the final demand effects of a price change must be estimated by the analyst before modeling them in IMPLAN to estimate the additional economic impacts of such changes.
