Introduction
Of the United States, Canada, and Australia, not a single one of these nations contains a national capital overlapping the largest city within their respective territories. In the United States, the capital is Washington, DC; while the largest city is New York. For Canada, the respective cities are Ottawa and Toronto, though the latter is a provincial capital city (for Ontario); and for Australia, the cities are Canberra and Sydney, respectively, though Melbourne is only slightly smaller than Sydney by population.
In the United States, state capital cities overlapping the largest cities within their respective states are quite rare, and the same can also be said for many provinces in Canada. In the territories further north in Canada, primate city dynamics exist to greater extents, including the communities of Whitehorse, Yellowknife, and Iqaluit within the Yukon, the Northwest Territories, and Nunavut; though the last community is already more isolated from elsewhere within the Arctic archipelago.
In Australia, almost all capital cities at the subnational level can be considered โprimateโ cities, though the national capital, Canberra, cannot be. The capital cities in Australia include Hobart, Tasmania; Sydney, New South Wales; Melbourne, Victoria; Brisbane, Queensland; Adelaide, South Australia; Darwin, Northern Territory; and Perth, Western Australia. While the Australian Capital Territory is often mistaken as being coterminous with the City of Canberra, the โgarden cityโ structure idealized for Australia actually results in suburban town areas, largely to the south of Canberra, also being included within ACT.
While Australian capital cities at the subnational level always correlate with the largest cities in their respective states and territories, the national capital, Canberra, is not. Canberra was specifically planned as the capital city out of consistent disputes between the coastal Cities of Melbourne in modern Victoria and Sydney in New South Wales. Unlike the Australian setup, the American and Canadian setups often lack such correlations or centralized power dynamics. For Canada, the Provinces of British Columbia, Alberta, Saskatchewan, Quรฉbec, and New Brunswick contain provincial capitals independent of the largest cities in each province. The other provinces not listed use the largest provincial cities as their respective capitals.
For the United States of America, the States of Alabama, Alaska, California, Connecticut, Delaware, Florida, Illinois, Kansas, Kentucky, Louisiana, Maine, Maryland, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New York, New Mexico, North Carolina, North Dakota, Oregon, Pennsylvania, South Carolina, South Dakota, Texas, Vermont, Washington, and Wisconsin all use capital cities separate from the largest cities in their respective states. While the aforementioned thirty-two states use capital cities outside the largest cities in their respective states, the eighteen other states are notable for more centralized power dynamics, often resulting in the political outcomes commonly associated with Arizona, Arkansas, Colorado, Georgia, Hawaii, Idaho, Indiana, Iowa, Massachusetts, Mississippi, Ohio, Oklahoma, Rhode Island, Tennessee, Utah, Virginia, West Virginia, and Wyoming.
