As in the other West India Islands the population is principally rural. There are probably not more than a dozen towns in the Republic with more than 1500 inhabitants. A government census of Santo Domingo City, the capital and largest urban center, taken in November, 1908, showed a population of 18,626, and the number is now estimated as 21,000. A census of Santiago de los Caballeros, taken by the municipal authorities in 1903, showed an urban population of 10,921, the present estimate being 14,000. The estimated population of Puerto Plata is about 7000; La Vega and San Pedro de Macoris are believed to have about 5000 inhabitants each, but in every other case the urban population falls below 3000. The population of the Dominican Republic is not scattered uniformly over the country, but is to be found chiefly in a fringe along the shore all the way from Monte Cristi to Barahona, and in the Cibao Valley. The most densely populated region is that part of the Cibao Valley known as the Royal Plain. In the mountainous interior there are vast stretches almost or entirely uninhabited; and remote valleys which have not been visited since the days of the conquest. The vicissitudes through which Santo Domingo has passed, the departure of so large a proportion of whites in the beginning of the nineteenth century and the intermingling of blood before and since that time have determined the character of the population. At the present time the pure negroes are in a minority, constituting probably less than one-fourth the entire population. The great majority of the inhabitants are of mixed Spanish and African blood, their color ranging from black to white. The lighter shades predominate, especially in the Cibao. There is also a sprinkling of pure whites, the majority of whom are to be found in the Cibao region or are foreigners residing in the larger cities. Many families would pass for white anywhere, showing absolutely no trace of colored blood, and it is difficult to believe confidential assurances of their intimate friends, indicating a different condition. A few families trace their ancestry back to the first Spanish colonists. As most of the blacks live south of the central mountain range the population of this region is a good deal darker than that of the northern part of the island. The census of Santo Domingo City in 1908 reported 7016 whites, 6934 colored persons and 4676 blacks, but apart from the circumstance that numerous white foreigners reside in the capital, it is probable that many persons were classified as white who would have been considered colored in the United States under the stricter rules there prevailing.
