Can I alter the PPI scorecard?

You cannot alter the PPI's questions, answer options, answer values, or look-up table without rendering the PPI inaccurate. Even a small change can have a big impact on the PPI's accuracy. The questions, responses, and scores on the PPI scorecard and look-up table are derived from recent national household expenditure or income survey s and should not be changed. The PPI was calibrated using indicators that were found through statistical means to be the most powerful indicators of poverty within a country. While the relevance of a particular indicator may vary from region to region within a country, the overall predictive power of the PPI remains strong. Changing any component of the PPI will undermine its predictive power and result in poor data. Learn more about how the PPI is designed.
