A list of the various types of ballot measures. States may have different legal definitions of each type; Wikipedia has more details about each type. These values are to help states with multiple types of non-candidate-based contests distinguish between each type; as such, the definitions in this table are simple guidelines. Ultimately it is up to the state or local election official to choose the value which best describes the ballot measure(s) in their jurisdiction.
