The De Agostini Atlas Calendar listed the area of Vatican City as 0.44 km2 (0.17 sq mi) in its 1930 edition[1] but corrected it to 0.49 km2 (0.19 sq mi) in its 1945–46 edition.[2] The figure of 0.44 km2 (0.17 sq mi) is still widely cited by many sources despite its inaccuracy. In 2019, the total population was 825, consisting of 453 residents and 372 nonresident citizens. For calculating the population density, only residents are considered.
