What Is Industrial Production Index (IPI)? How It Measures Output


The Industrial Production Index (IPI) is a measure used by economists to track changes in the output from the industrial sector of an economy, typically aggregated from sectors like manufacturing, mining, and utilities. It reflects the volume of production for a given period relative to a base period, often normalized to a value of 100. In essence, it provides a gauge of the country or region’s industrial performance to identify periods of growth and contraction.

Key Takeaways


  1. Definition of Industrial Production Index (IPI): The Industrial Production Index (IPI) is a measure of output that pertains to the business sector. It is a crucial economic indicator that gauges the performance of manufacturing, mining, and utilities within an economy. As such, it’s a tool that provides valuable insights into the health of an economy’s industrial sector.
  2. How IPI is Used: Policymakers, economists, and market analysts use the IPI to inform their decisions and strategies. The index is often used to predict future levels of economic activity, performance of the industrial sector, and as a gauge for inflationary or deflationary pressures. A high IPI is usually a sign of a robust economy, while a low IPI can indicate a potential downturn.
  3. How IPI is Measured: The IPI is typically expressed as a percentage change from a base year, which allows comparisons between different time periods. The calculation of the index involves using data about output volumes in various sectors, which is often obtained through surveys of businesses. These surveys collect data on things like the quantity of goods produced, hours worked, and the use of capacity in these sectors.



The Industrial Production Index (IPI) is a crucial economic indicator that measures the output of the industrial sector in an economy. It encompasses segments such as manufacturing, mining, and utilities, providing an evaluation of their performance over a specific period of time. Essentially, the IPI charters the rate of change in the production level of industrial goods, acting as a pulse check for the health of the economy and industrial potency. With an understanding of IPI, economists, investors, and policymakers can gauge the current economic activity level and predict future performance. When the IPI increases, it usually implies economic expansion and could indicate an increase in employment levels, while a decrease may suggest a recession. Therefore, keeping track of IPI is critical for strategic planning and decision-making in businesses and finance.


The Industrial Production Index (IPI) serves as a critical barometer in assessing the overall health and functionality of an economy’s industrial sector. This tool is widely utilized by economists, analysts, businesses, and government bodies to gather insights into the manufacturing, mining, and utility sectors’ production efficiency. By analyzing the IPI, these entities can understand the output trends in these sectors, comprehend their relationship with the overall economic growth, and project future production scenarios. As such, this is an invaluable instrument for economic policymakers in developing countries that rely on industrial production for their GDP.The IPI’s primary function in measuring output is to establish a correlation between the production volume within industrial sectors and the broader economic growth. By highlighting industries that are performing exceptionally well and sectors that are lagging in output, the IPI allows for a strategic allocation of resources to maximize the industrial performance of an economy. The result derived from the IPI calculations can inform businesses on expansion or contraction decisions, economists on understanding economic cycles and trends, and governments on drawing their fiscal and economic policies. Therefore, the Industrial Production Index not only helps track the performance of the industrial sector but also provides meaningful insights that influence macroeconomic decisions and strategies.


The Industrial Production Index (IPI) measures the manufacturing, electric, gas and mining output of an economy. It’s a valuable tool for economists and investors who can examine the trends in the IPI to make informed predictions about future performance. Here are three real-world examples:1. **Manufacturing Industry**: In the United States, the Federal Reserve calculates the IPI for several major market and industry groups. For example, let’s look at the automobile industry. If the IPI chart shows a continued rise over several months, it suggests increased car production. This echos strong consumer demand, leading economists to predict a robust economy and offering investors insights into the potential profitability of car manufacturers and related businesses.2. **Energy Production**: The IPI is also used to measure output in the energy sector. If natural gas production is higher, indicated by a rising IPI, it could infer either increased demand or technological improvements facilitating better production. Policymakers can use these insights to manage national energy policies, while investors can use this for decision-making in energy stocks.3. **COVID-19 Impact on Industrial Production**: The IPI became an especially important indicator during the COVID-19 pandemic. In many countries, IPI figures showcased significant drops reflecting factory shutdowns and overall reduced industrial activity. Economists used this data to quantify the impact of the pandemic on various industrial sectors and predict the speed and strength of economic recovery post-pandemic.In each instance, the IPI provides valuable data on industries’ health and economic predictions, making it critical to business and finance professionals.

Frequently Asked Questions(FAQ)

What Is the Industrial Production Index (IPI)?

The Industrial Production Index (IPI) is a critical economic indicator that measures the output of various sectors in an economy such as mining, manufacturing, and the electric and gas industries. It monitors the levels of production across these sectors to provide insight on the performance and health of the country’s industrials.

How is the Industrial Production Index (IPI) calculated?

The IPI is calculated by measuring the real production output of manufacturing, mining, and utilities and comparing it to a base year. It’s then weighted based on the contribution of different industries to the gross domestic product (GDP).

What does the Industrial Production Index (IPI) indicate?

The IPI indicates changes in industrial sectors and can provide insights into economic growth and decline. An increase in the IPI suggests industrial growth and can signify economic expansion, while a fall in the IPI might indicate an economic slowdown or recession.

What elements does IPI include?

The IPI includes three categories: Manufacturing, which represents most of the total output measured; Mining, which includes the extraction of natural resources like coal or oil; and Utilities, which include electric and gas utilities.

How often is the IPI reported?

The IPI is reported monthly by the Federal Reserve in the United States and other respective financial agencies in different countries.

How does the IPI affect businesses?

The IPI is commonly used by businesses to help with decision making, budget forecast, sales, and investment strategy. A rising IPI may suggest that businesses in the sector are likely to increase their activity, while a declining IPI may suggest the opposite.

Can the IPI predict future economic activities?

Yes, the IPI can be used as a leading economic indicator, providing an early sign of the health of the economy. Changes in industrial production can forecast significant changes in the unemployment rate, wage growth, and overall economic performance.
