This article is designed to offer IMPLAN users some important descriptions of, temporary solutions for, and status updates regarding known technological issues which have been identified and are actively being addressed within IMPLAN. Should you encounter any issues which are not addressed in this article, please let us know by contacting us at email@example.com. Issues which were previously identified, but have since been resolved, are documented in IMPLAN's product release notes which are published upon the release of new features and capabilities within the IMPLAN tool.
ISSUES BEING ADDRESSED:
Each of the technological bugs described below have been identified and are being addressed (as you read!) by the IMPLAN Product Team. So don't worry—we're on it! But, should you encounter any of these issues between now and the deployment of their official fixes, there are workarounds which can provide effective (albeit manual) solutions in the meantime.
1. NO NOTIFICATION WHEN AN INDUSTRY DOES NOT EXIST IN A REGION
When running an Industry Event on a Sector that does not have any activity (no Output, no Employment, etc.) in the Region used in the analysis, the user will get all zero results. This is because there is no data or Sector averages for that industry in the Region, which is necessary for IMPLAN to estimate the effect of some change in that Sector within the given Region. IMPLAN does not provide any notification to the user that the Sector does not exist. When running an Industry Event on a Sector that doesn't exist in the Region in combination with other Events that successfully produce non-zero results, it is very possible to overlook the fact that one of the Events has produced all zero results.
You can ensure the Sectors you will be impacting exist by checking for data on the given Sector in the Region Details. Study Area Data (Industry Summary table) is a great place to check. Users can model the effects of a new Sector being introduced to a given Region by either first adding the Sector by customizing your Region and then modeling the effect using an Industry Event or by taking an Analysis-by-Parts approach.
2. THE US TOTAL AND METROPOLITAN STATISTICAL AREAS (MSA) APPEAR IN THE SEARCH, BUT ARE NOT AVAILABLE IN USER-DEFINED INDUSTRY AGGREGATION SCHEME PROJECTS
THE US TOTAL AND METROPOLITAN STATISTICAL AREAS (MSA) APPEAR IN THE SEARCH, BUT ARE NOT AVAILABLE IN USER-DEFINED INDUSTRY AGGREGATION SCHEME PROJECTS
When working in a Project with the US Total or a user-defined Industry Aggregation Scheme, the US Total and MSA regions appear when searching for them in the search field. However, they should not be searchable in a user-defined Industry Aggregated Project because these Regions are not actually available.
Build the US Total or the MSA as a Combined Region by selecting and combining the areas included in the region from within the user-defined Industry Aggregated Project. This is easily accomplished using the Regions List feature on the Region screen.
3. DOWNLOADED RESULTS DIFFER IN EXCEL VERSUS CSV
If you download the same table on the Results screen in both .xlsx and .csv, you will see different values. This is because there is a difference in the number of decimal places used in rounding between the two formats.
When downloading data, always download as a .csv, which has now become the default setting for all Results tables. We also recommend selecting "Unformatted (no rounding, special characters, etc.)" in the download popup.
4. RESULTS NOT POPULATING WHEN USING OLD CUSTOM AGGREGATION
If you are using an Aggregation Scheme that was built prior to the release of the 2019 data, your Results will not completely populate. This is because there aren't any 2019 deflators or margins associated with the Aggregation Scheme.
In order to fix this, you will need to rebuild the Aggregation Scheme with the 2019 data and replicate your project.
5. OCCUPATION EMPLOYMENT RESULTS NOT POPULATING WITH CUSTOM INDUSTRY
When a custom Industry is added to your Region, the Occupation Results will not include employment values. This is because when customizing a Region, there is no way to tell IMPLAN the split between Wage & Salary Employment and Proprietor Employment.
IMPLAN is working on a solution to ensure that the Employment Values are populating in the Results. Stay Tuned.
6. EDITED ADVANCED SPENDING PATTERN EVENT RESETS TO DEFAULT STATE TO ORIGINAL
When Duplicating a Project, any Spending Pattern Event(s) with Advanced Edits are reset to the default Spending Pattern for that Industry or Institution.
We recommend taking notes of the changes you make so that you can copy them over to the duplicated project.
7. TOPI PAYMENTS TO THE FEDERAL GOVERNMENT ARE NEGATIVE IN THE 2020 ANNUAL DATA SET
An error occurs when regional Taxes on Production and Imports (TOPI) payments to the Federal Government are negative for an Industry. When this occurs, the shares of TOPI distributed to the various levels of government are incorrectly specified. This does NOT affect other economic indicators like Output, Employee Compensation, Employment, or Total Value Added either in the Region Details or in Results of an impact analysis. Nor does the Total TOPI paid regionally change, only the distribution of TOPI to Federal and State & Local Governments. The error does NOT affect regions which have positive TOPI payments to all government institutions, which is the majority of regions. Thus, this is a rare occurrence generally. However, with the PPP loans of 2020 included as negative TOPI payments the error has become more frequent.
We are looking into a solution and working to identify the models in which this error occurs. If this error occurs, we recommend the user estimate their own distribution of Direct Taxes using the Total Direct TOPI results.
DATA LIBRARY ISSUES BEING ADDRESSED:
1. RESULTS NOT POPULATING WHEN DATA LIBRARY AND IMPLAN ARE OPEN
If you have an instance of Data Library open at the same time as the results of an IMPLAN project, it is possible that one, or both of these pages will not load results. This may also result in a user not being able to save Data Library Explores to a Dashboard.
To fix this, refresh the page, and whenever possible avoid having both IMPLAN results and Data Library open simultaneously.
