What is Gross Metropolitan Product?

Gross metropolitan product (GMP) is a measure of the value of all final goods and services produced within a metropolitan area during a year. GMP is similar to Gross Domestic Product (GDP), which measures economic output and activity at the national level.  On this page you will find quarterly estimates of imputed Gross Metropolitan Product.

Why is it "Imputed"?

Unlike at the State and National level, GDP, or economic output, is rarely precisely measured at a regional level the size of Northwest Indiana. In order to provide a measure of the economic output for Northwest Indiana we rely on a variety of regular and irregular data to impute, or assign value by inference to, an estimate of Northwest Indiana's Gross Metropolitan Product. Our data come from different sources, including our own Northwest Indiana Coincident Index, some traditional government datasets as well as singular reports both private and public. For more information please see the notes and data sources section below.

How accurate is GMP?

One way to evaluate the accuracy of the Northwest Indiana Imputed GMP is by comparing its estimates to other measure of Northwest Indiana output and income not used in its construction. The graph below shows Northwest Indiana real GMP per capita in comparision with two other recent measures. The first is real earnings per worker for Northwest Indiana, which is published by the Bureau of Labor Statistics and the second is two estimates of Gross Regional Product for the same Northwest Indiana region, published by the Minnesota IMPLAN Group, Inc. As the graph shows, the NWI imputed GMP is consistent with these other measures.
