Methodology: 50-State Competitiveness Dashboard
Methodology
Our 50-State Competitiveness Dashboard provides insights into where Massachusetts stands in the national economic landscape through indicators of state competitiveness. These indicators are aggregated into six different indices: Fiscal Stability and Public Management, Talent and Workforce, Tax Environment, Growth and Innovation Climate, Cost of Doing Business, and Quality of Life. Each consists of a weighted combination of datasets. The Council updates the competitiveness indices based on the availability of new source data and produces reports bi-annually based on a computation of the most up-to-date data available. The methodology for computing the competitiveness indices is given below.
Data Pre-Processing
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 in the computation of the index ranking. 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 that only vary by a few tenths of a point, some are numbers in the millions representing populations, or Gross State Product. 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 a more favorable policy outcome than a high rate. Negative coefficients correct for data with inverted trends.
MATTERS Index Computation
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:
