The territory of the Republic has an area of more than 1,130,000 square miles, and its population amounts to no more than 5,792,807, which gives a density of 5·1 persons per square mile. One should also recollect, in order to grasp the true significance of these figures, that of those 5,792,807 inhabitants, 157,963 inhabit the 43,000 acres which form the site of Buenos Ayres; so that only 4,634,841 remain to people the rest of the country, a fact which still further lessens the density of the population. This density varies in different regions and in different Provinces; thus the eastern or coastal region, formed by the Federal Capital and the Provinces of Buenos Ayres, Santa Fé, Entre Rios, and Corrientès, has 17·08 inhabitants to the square mile, while that of the centre, which comprises Córdoba, San Luis, and Santiago de l’Estero, has only 5·8. As we penetrate further inland the density grows still less, until in the western or Andean region, formed by the Provinces of Mendoza, San Juan, La Rioja, and Catamarca, the figure is barely 2·7. In the northern region, embracing the Provinces of Tucuman, Salta, and Jujuy, there are 5·23 inhabitants per square mile.
