The people who vote
Assuming you're asking about U.S. states. Number of electoral votes is based on the state's population, as determined by the U.S. Census.
In the Election of 2012, the state with the largest number of electoral college votes will be California, with 55 electoral votes.
The number of a state's electoral votes is the state's total number of U.S. Senators and Representatives, so every time a state gains or loses House seats, it gains or loses the same number of electoral votes.
Each state has electoral votes equal to the total of the 2 representative the state has in the U.S. Senate plus the number of representative the state has in the House of Representatives. Since every state has two senators and at least one representative to the House, every state has at least 3 electoral votes.
The number of electoral votes allotted to each state directly depends on the number of residents. Therefore, states with lower populations will have less electoral votes. Montana and Wyoming each only have 3 electoral votes, but the state of California has 55.
I assume you mean "state". Each state has a minimum of three electoral votes.

The total number of electoral votes in the U.S. Electoral College is 538. Each state has electoral votes equal to the total of the 2 representative the state has in the U.S. Senate plus the number of representative the state has in the House of Representatives. Since every state has two senators and at least one representative to the House, every state has at least 3 electoral votes. The District of Columbia gets 3 electoral votes. Therefore, the total number of electoral votes is 538 - 100 (senators) + 435 (representatives) + 3 (for DC). A majority is 270 - one more than half of the total number of 538.
The number of US representatives is exactly the number of electoral votes minus two. (The number of electoral votes for a state is the defined to be the size of its delegation to Congress, including its two senators. )
The number varies between states. It is based on the number of representatives that state has. Each political party has the same number of electoral members.
