About this ranking

Age that divides the resident population into two halves of equal size. Spain and the EU: on 1 January. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span. Canada: on 1 July, Statistics Canada population estimates.

Every value in the ranking comes from the same publisher and the same period, so the cities are compared on one definition. 1 cities with data in other periods have no value for 2023 and are left out rather than filled from another source. Equal values share a rank.
