Appendix

Table A1 breaks down the overall readiness score of each state by category. These are weighted averages of the individual indicators grouped by category, so the average of these categories is not equivalent to the weighted average of all the pooled indicators used for the rankings.

Table A2 provides state-by-state information on initiative processes and adoption history. States that attempted but failed to adopt initiative processes are also included. For each state, the table indicates which types of initiatives are allowed (if any), the year of and method of adoption or attempted adoption, and, where successful, the relevant constitutional provision that enshrined initiative or referendum into law.

Table A3 lists the source, mean, and range for all the variables used to calculate the readiness scores. Where applicable, the table also lists the year for which the data is relevant. The table shows the mean and range for each variable before standardization.
