About this chart

Buenos Aires stands well above the other cities in Argentina: its 14.02 million people in 2025 are about 9.60 times the 1.46 million in second-place Cordoba. Buenos Aires also led the 1975 ranking, when the UN series put it at 8.56 million. Rosario occupies third place in 2025 at 1.15 million. These are populations of urban areas defined consistently by the UN, rather than administrative city limits.

The UN projects Buenos Aires to lead in 2050 at 14.24 million people. The figures after 2025 are projections. The Degree of Urbanization identifies contiguous dense settlements, so these totals can differ from municipal and metropolitan statistics. The historical ranking is useful for comparing positions; changing settlement boundaries mean it should not be treated as a measure of growth within fixed city limits.
