The number of senators is decided by the legislation of the country concerned.
General a higher population of a region would have more senators but this is not a universal rule.
There are 76 senators in the Australian Senate, with 12 from each of the 6 states and 2 each from the autonomous internal territories.
Two (2) each for the Northern Territory and the Australian Capital Territory. Others, such as the external territories of Christmas Island and Cocos (Keeling) Islands, do not have their own senators. For electoral purposes these territories form part of other (state) electorates and are represented by the relevant senators of those states.
I think this is actually 2 questions. Every one of the US states have voting members in Congress. Usually each state has 2 Senators and a number of Representatives (based on the population of the state.) However, US territories are not states and do not have voting members in either the Senate or House of Representatives.
All States in the United States have 2 senators, therefore Arizona has two US Senators
two all of the states have two state senators
All states have 2 US Senators.
2. Every state has 2 senators. There are 100 senators and 50 states.
Mexico has 2 territories and 29 states.
There are 100 Senators in the United States. 50 States and each contain 2 Senators.
Georgia has 2 United States Senators. Every state has 2 Senators, regardless of population.
There are 2 Senators from each of the 50 states, as specified in Article One, Section Three of the US Constitution. If additional states join the Union, the number of Senators will increase to accommodate these new states at 2 Senators per state, with no restriction on the total number. There are two senators for each state and 50 states, making 100 senators altogether.
All states in America have senators. Each state has 2 senators that represent the citizens of North Carolina in the United States Senate.
