Capacity utilization · total industry

## What this measures

Total industry capacity utilization measures the share of productive capital stock currently in use across manufacturing, mining, and utilities. It reveals how much slack remains in the economy's installed production capacity.

## Why it matters

High utilization signals that firms are nearing the limits of existing capacity, which can lead to bottlenecks, rising input costs, and pressure to invest in new capital. Low utilization suggests abundant room to increase output without new investment, often indicating weak demand or excess prior buildout.

## How to read it

The value is reported as a percentage. Rising utilization means firms are using more of their installed capacity; falling utilization means more capacity sits idle. Compare the level to historical averages to assess whether slack is abundant or scarce.

## What it does not say

It does not reveal profitability, demand trends for specific industries, or whether existing capacity is modern and efficient. The series also does not indicate whether firms plan to expand capacity or reduce it.
