The Maritimes is currently represented in the Canadian Parliament by 25 Members of the House of Commons (Nova Scotia – 11, New Brunswick – 10, Prince Edward Island – 4) and 24 Senators (Nova Scotia and New Brunswick – 10 each, Prince Edward Island – 4). This level of representation was established at the time of Confederation when the Maritimes had a much larger proportion of the national population. The comparatively large population growth of western and central Canada during the immigration boom of the 20th century has reduced the Maritimes' proportion of the national population to less than 10%, resulting in an over-representation in Parliament, with some federal ridings having fewer than 35,000 people, compared to central and western Canada where ridings typically contain 100,000–120,000 people.
