Final answer:
The electoral number of a state is determined by the number of representatives and senators that state sends to Congress based on its population.
Step-by-step explanation:
The electoral number of a state is determined by the number of representatives and senators that state sends to Congress. This is based on the state's population, as determined by the Census that is conducted every 10 years. Each state is guaranteed at least one representative, and the total number of representatives is capped at 435. The number of senators is always two per state. So, for example, a state with a higher population will have more representatives and therefore a higher electoral number.
