A composite index of six indicators measuring each state's economic performance relative to the U.S. average. 100 = U.S. baseline; above 100 indicates stronger performance, below 100 indicates weaker performance.
- What it measures: The Ember State Performance Index combines six key indicators into a single score that captures whether a state economy is running faster or slower than the national baseline. A score of 100 indicates that a state's overall economic performance is aligned with the national trend. Scores above 100 reflect stronger relative growth, while scores below 100 reflect weaker growth. Individual indicators may still outperform or underperform the U.S. even when the composite index is near 100.

- Methodology: Each indicator is standardized relative to the U.S. average using z-scores, allowing states to be compared across metrics with different scales and volatility. States performing above the national trend receive positive contributions, while states below trend receive negative contributions. Extreme values are capped to reduce the influence of outliers. The standardized indicators are then combined using the weights above and scaled so that 100 represents the U.S. average.
