It was the tenth census combined with the nine previous censuses taken by Spain. The day used for the census was Friday November 10, 1899 with a total population counted as 953,243 - an increase of 154,678 or 16% over the previous 1887 census taken by the Spanish government.

Method of tabulation
It was taken that to save time, the tabulation should be done by machine and not by the old hand-tally system. As the machines invented by Mr Herman Hollerith were successfully used in the earlier eleventh and were to be used for the twelfth U.S. census, it was adopted.

Age
Data of the total population by median age.

Birthplace
The number of foreign-born returned by the census is 13,872 or about 1.5% of the total population. There were few regions in the western hemisphere in which the proportion of natives is so high and that of the foreign-born so low. Of the total number of foreigners 5,935 or 43 per cent were found in the three cities of San Juan, Ponce and Mayagüez. Of the total foreign-born, 7,690 or 55% were born in Spain.

Race
With reference to race, the population of Porto Rico is divided by the census into two main classes - those who are and those who are not White. The number belonging to each of these classes is as follows: The colored in the table includes very few (75) Chinese and many persons of mixed white and Black African blood as well as pure Black. Somewhat more than three-fifths of the population of Porto Rico are white and nearly two-fifths are partly or entirely negro or Black. By the 1899 census five-sixths (83.6 per cent) of the total colored were returned as of mixed blood.
