Adelaide is the oldest of the large capitals, with a median age of 39.3, and has the narrowest gap between its richest and poorest suburbs.

When nearly the whole city is within 45 minutes of the centre, a single site can serve it, and a network of two or three stores overlaps quickly. In Adelaide the first question for a second store is how much of the first one’s market it would share. The narrow income range means fewer extremes: there is no Toorak or Mosman to anchor a premium format, but also fewer areas where everyday spending is weak. The inner east and south are the top of the range. An older city does not spend more on health per resident, A$3,726 a year against A$3,823 nationally, but the business counts show an older market: aged care and hairdressers per resident are above the other capitals. The young north, around Playford and Munno Para, is the exception, and the growth. FAQ ## What else do people ask about Adelaide? ### What is the population of Adelaide?
