Buenos Aires has a population of 11,680, making it the 45th largest place we list in Costa Rica. It is in Puntarenas Province.
Buenos Aires holds 0.23% of Costa Rica's 5,174,789 people. San José, the largest place we list there, is 29 times its size. The World Gazetteer published 11,680 for Buenos Aires in 2005 and GeoNames still carries that same figure, so there is no measured change to report.
The 2005 figure comes from the World Gazetteer archive restored on this site. Why figures differ.

Figures are the latest available in GeoNames (CC BY 4.0), which draws on national censuses of varying dates — treat them as recent, not same-year. Country totals are UN World Population Prospects 2024 (medium variant) where the UN lists the country separately; the handful it reports under a parent state keep a GeoNames figure and are marked as such.
