MATTERS provides additional insights into the national economic landscape by leveraging the data in the MATTERS system to create indicators which measure the competitiveness of states. These four MATTERS indices align with each of the data categories in the MATTERS system: Talent, Tax/Financial Climate, Cost of Doing Business and Quality of Life. Each consists of a weighted combination of datasets in the MATTERS system.

The state rankings are displayed in the overview maps on the MATTERS homepage. A detailed view of the most recent indexes for each state, along with the values of the underlying data, can be accessed by clicking through to the individual State Profile pages.

The MATTERS indices are published biannually, coinciding with the release of the latest CEO Competitiveness survey. At each update, a new version of the indices will be computed using the most up to date data available. The methodology for computing the MATTERS indices is given below.


Missing Values: The metrics in the MATTERS system often have data available for different years. If a value for some metric is missing for a given year, the closest previous value is used. If there is no previous value, the closest possible value is used.

Normalization: The values of metrics in the system vary greatly, some are percentages which only vary by a few tenths of a point, some are numbers in the millions representing populations, or GDP. The values must be normalized so that large values do not dominate. We use a standard z-transform to scale and center the data. For each metric, we subtract the mean value across all states, and divide by the standard deviation. This results in each metric having a mean of zero and standard deviation roughly equal to one, making the different metrics comparable.

Inverted Trends: Typically when looking at trends, high values are considered better than low values. However, for some metrics the opposite is true. For instance, a low unemployment rate is preferred to a high rate. Negative coefficients correct for data with inverted trends,

Values vs. Rankings: States can be ranked according to their computed values. However, this ranking does not capture all the information in the index. The computed values fall in a range of roughly -100 to 100. While these values are not easy to interpret on their own, they do show relationships between states. Therefore, the raw values are available for inspection and analysis in the Data Explorer. Rankings are shown in the State Profile page.


Each index is computed by combining a set of datasets (or metrics) \( \{m_1, m_2 ...m_n \}\), as a weighted sum. The coefficient \(c_i\) for each dataset determines its weighting in the sum. The general formula for each index is:

$$\frac{c_1 * m_1 + c_2 * m_2 + \dots + c_n *m_n}{c_1 + c_2 + \dots +c_n}$$

The metrics used and their weights are given in the tables below.
