"We shall not be surprised at the partial contradiction found in the tables of population when we taken into consideration all the difficulties that have been encountered in the centres of European civilization, England and France, whenever the great operation of a general census is attempted. No one is ignorant, for example, of the fact that the population of Paris, in 1820, was 714,000, and from the number of deaths, and supposed proportion of births to the total population, it is believed to have been 520,000, at the beginning of the eighteenth century; yet during the administration of M. Necker, the ascertained population was one-sixth less than this number."
The process of census taking even in this twentieth century is an enormous undertaking and not free from error. How much more difficult must it have been in a country where it was to the interest of the intelligent to suppress the facts, where a large proportion of the population was still in slavery, and where means of communication from place to place were far from adequate!
Baron Humboldt after very careful calculation estimated the population at the close of 1825 to be as follows:
| Whites | 325,000 |
| Free colored | 130,000 |
| Slaves | 260,000 |
| Total | 715,000 |
This was nearly equal to that of the British Antilles, and about twice that of Jamaica.
During the first half of the nineteenth century three additional censuses were taken:

J. S. Thrasher, translator of Baron Humboldt's admirable work on Cuba, and himself an authority of note, offers the following interesting and suggestive discussion of the census of 1846:
"The slightest examination leads to the belief that there is some error in the figures of the census of 1846; and we are inclined to doubt its results, for the following reasons:
"1st—During the period between 1841 and 1846, no great cause, as epidemic, or emigration on a large scale, existed to check the hitherto steady increase of the slave population, and cause a decrease of 112,736 in its numbers, being nearly twenty six per cent. of the returns of 1841; which apparent decrease and the annihilation of former rate of increase (3.7 per cent. yearly), amount together to a loss of 47 per cent., in six years.
