The city has a population of over a million people, two-thirds of the state population. It is situated on the plains between Gulf Saint Vincent on the west and the Adelaide Hills, part of the Mount Lofty Ranges, on the east. The result is an urban area that is barely 20 km wide, but almost 100 km from Gawler in the north to Sellicks Beach in the south. | The city has a population of over a million people, two-thirds of the state population.
