Perceptions of dynamism were gathered from two survey items. Respondents were asked how much they agreed or disagreed with the following prompts: 1) “My district’s environment—the political, social, and economic factors—is relatively stable”, and 2) “There is a great deal of uncertainty in the environment in which my district operates.” Values for the second prompt were reversed and then added to the values of the first prompt to create an additive index of subjective dynamism. Higher values indicate greater dynamism.
