By observing the increase of population in different periods of five years, he considered it satisfactorily proved by the _Tablas Geographico-politicas_, of 1803, that the augmentation, in favorable years, was at the rate 1-4/5 _per cent_. By applying this ratio to the census of the _Tablas_, which gave in 1803, 5,764,731 inhabitants, we shall have an increase of about 105,000 yearly; and if we calculate at this rate of augmentation for the 46 intervening years, we find in 1850 an increase of 4,830,000, or a grand total of 10,594,731. In the year 1842, however, when an estimate was made of a basis of population, upon which to found a call for a Congress to form a new constitution under the plan of Tacubaya, in 23 Departments or States and Territories, exclusive of Texas, the government calculated that there were 7,015,509 inhabitants.
