What is the relation of mathematics with civics?

Answer 1

Civics requires citizens to make rational choices in the way they govern themselves or are governed by their elected representatives. Even unelected rulers will want to keep certain parts of the population (the army?) happy so as not to precipitate a revolution!

Such rulers will want to base their decisions on evidence which will depend on mathematical analyses of the evidence available to them. The available evidence, in turn, will depend on procedures to collect and process raw data.

For example, if you had no idea of the state of the economy, any action that you take would be speculative. And the only way to get some idea of the state of the economy would be to collect information on various economic factors such as inflation, employment, trade, business confidence etc.

The same sort of argument can be advanced for the health, education of the population.
