There are various ways to customize an IMPLAN Event beyond adding an Event Value to analyze. Each Event Type in IMPLAN has additional Event options that allow users to add more detail to an IMPLAN Event outside of specifying an Industry (or Commodity, Household, etc.) and a primary Event Value. Note that these options will vary depending on the type of Event chosen. All Event Types provide users the option to segment their impacts by Event Tags, whereas some Event Types can have secondary Event Values applied to further define the economic activity being modeled. This article will walk through all available Event options in IMPLAN and which Event Types they are available for.



Event Tags are a feature in IMPLAN that allows users to organize events within projects by creating up to 100 self-defined categories. This process can save time and help declutter the screen for easy viewing. The Event Tags will follow from the Impacts screen to the Results screen and have filtering capabilities.


More Options allow users to Duplicate an Event or Delete an Event.


Click and hold the Handle to drag an Event over to the appropriate Group. When the Group is highlighted a teal color, release the click to drop the event into the Group. 

Use the checkbox at the top of the Impact Screen to Select/Deselect All Events or click Filter Tags to sort a group of Events. Both of these tools can be used to drag and drop multiple Events at a time. 


The following Event Types have Advanced Fields for a user to further customize the Impact. 

  1. Industry Output
  2. Industry Employment
  3. Industry Employee Compensation
  4. Industry Proprietor Income
  5. Commodity Output
  6. Industry Spending Pattern
  7. Institutional Spending Pattern

When a user utilizes the Advanced Fields, the icon on the event will change to teal to indicate that an entry has been made for that Event. 


The four Industry Event Types (Industry Output, Industry Employment, Industry Employee Compensation, and Industry Proprietor Income) are appropriate for analyzing a change in an Industry’s production. Picking among the four types should be determined based on the known value for the industry. 

When more than one of the Event Values is known, those additional values can be entered in the Advanced Field. Adding additional fields will overwrite the production function values used in the analysis for any entered fields. When adding more than one additional value to the Industry Output Event, consider using the Industry Impact Analysis (Detailed) Event Type.

Industry Events also have a Margins option as an Advanced Field. This Advanced Field is only enabled in an Industry Event when the Specification is one of the Retail or Wholesale Industries in IMPLAN. Learn more about Retail and Wholesale: Industry Margins.


Commodity Output Events have two Advanced Fields options, the Local Purchase Percentage (LPP) and Margins. 

Local Purchase Percentage are applied to each Commodity Output Event. The default is set to 100% for non-marginable Commodities and set to “SAM” or Regional Purchase Coefficient for all marginable Commodities. 

Margins are only enabled in an Commodity Output Event when the Specification is a Commodity that can be sold via retailer or wholesaler, or is a retail or wholesale service Commodity.  Learn more about Retail and Wholesale: Commodity Margins


Industry and Institutional Spending Pattern Events have several options in their Advanced Fields. In addition to the Local Purchase Percentage field, Spending Patterns also have a Percentage field to adjust the allocation of spending across the included Commodities. Commodities can be added or removed from the Advanced Field. Spending Patterns can also be Normalized and Reset from the Advanced Fields. Learn more about Editing Spending Patterns.
