BEA Announcement: New RIMS II Multipliers are available Inbox

PLEASE NOTE THIS FIRST: 

RIMS II multipliers are based on 2017 national benchmark input-output data and 2023 regional data. These multipliers were first released in April 2025.

The Regional Input-Output Modeling System (RIMS II) is a model developed by the Bureau of Economic Analysis (BEA) to estimate the economic impacts of changes in an area's economy, such as a new project or event, on a regional scale. 

It uses "multipliers" to calculate the total impact, including both direct and indirect effects, on industrial output, earnings, and employment. RIMS II is used by government agencies, businesses, and consultants for various economic impact studies

 

 

 

BEA Announcement: New RIMS II Multipliers are available

Updated Regional Input-Output Modeling System (RIMS II) multipliers are now available. The new multipliers are based on 2023 regional data and 2017 national benchmark input-output data and are available for 376 detailed industries and 64 industry aggregates.

Multipliers may be ordered by region or industry:

• By region: Multipliers are provided for all the industries for the region that is purchased. Each region costs $275.
• By industry: Multipliers are provided for 50 states and the District of Columbia for each industry that is purchased. Each industry costs $75.

For more information, please contact the RIMS II staff at 301-278-9313 or rims@bea.gov or visit the RIMS II website at https://apps.bea.gov/regional/rims/rimsii/.

Welcome to the RIMS II Online Order and Delivery System

The Regional Input-Output Modeling System (RIMS II), a regional economic model, is a tool used by investors, planners, and elected officials to objectively assess the potential economic impacts of various projects. 

• This model produces multipliers that are used in economic impact studies to estimate the total impact of a project on a region. 
• The idea behind the results of RIMS II is that an initial change in economic activity results in other rounds of spending — for example, building a new road will lead to increased production of asphalt and concrete. 
• The increased production of asphalt and concrete will lead to more mining. Workers hired due to the increase in economic activity will spend more in the region.

What are RIMS II multipliers?

Regional Input-Output Modeling System (RIMS II) multipliers provide a measure of the effects of local demand shocks on total gross output, value added, earnings, and employment. The multipliers are used by investors, planners, and elected officials to objectively assess the potential economic impacts of various projects.

RIMS II multipliers are based on 2017 national benchmark input-output data and 2023 regional data. These multipliers were first released in April 2025.

How much do multipliers cost?

$275 per Region
Multipliers are provided for all industries in the model for the region that is ordered. The region must contain one or more contiguous counties.

$75 per Industry
Multipliers are provided for 50 states and the District of Columbia for the industry that is ordered.

BEA Updates 

Regional Economic Impact Tool

September 3, 2019

The U.S. Bureau of Economic Analysis has updated its regional economic modeling system used by local planners, investors, and policymakers. This tool can help assess the potential economic effects of a new corporate headquarters, a highway project, or new regulations.

Economic impact studies use the Regional Input-Output Modeling System, known as RIMS II, to analyze how projects will ripple throughout county, state, or regional economies. For example, building a new road leads to increased production of asphalt and concrete. That leads to more mining. Workers benefiting from these increases will spend more money, perhaps on eating out or entertainment.

RIMS II is based on BEA’s national supply-use tables, also called the input-output accounts. These detailed tables show the goods and services produced by hundreds of industries and how those goods and services flow to other industries or consumers, for a comprehensive picture of relationships throughout the U.S. economy. 

RIMS II uses BEA’s regional data to focus the picture on economic relationships within a specific area. For example, a bakery might buy eggs locally and cake boxes from afar. If a new corporate neighbor starts ordering lots of cakes, the bakery will spend more money in the local economy on eggs, but its increased box spending goes outside the region.

BEA uses a region’s economic relationships to calculate “multipliers,” used to estimate a project’s impact on the region’s total gross output, value added, earnings, and employment.

RIMS II was updated Aug. 29 to reflect BEA’s new 2012 benchmark supply-use tables (the benchmark is typically updated every five years) and 2017 regional economic data. The new multipliers are available for 372 detailed industries and 64 industry aggregates.

The RIMS II model is customized for each customer’s needs. Multipliers may be ordered by region or industry:

• By region:  Multipliers are provided for all the industries for the region that is purchased. Each region costs $275.
• By industry:  Multipliers are provided for 50 states and the District of Columbia for each industry purchased. Each industry costs $75.
