The trend over time.
What Industrial Production YoY measures.
The year-over-year percentage change in the Federal Reserve's Industrial Production index, which covers manufacturing, mining, and electric and gas utilities.
Industry is a minority of U.S. output but it is cyclical, so it turns before the broader economy. Utilities respond to the weather, which can distort a single month.
Why it matters.
Factory output directly influences job creation and corporate profits, which affect your employment prospects and investment returns. When industrial growth stalls, it often signals economic slowdown ahead, affecting everything from wage growth to interest rates on your mortgage.
