Memphis ............................... 48.8 Washington ............................ 31.1 New Orleans ........................... 27.1 Louisville ............................ 19.1 St. Louis ............................. 6.2 Philadelphia .......................... 4.8 Baltimore ............................. 15.6 Some smaller Southern cities have, of course, a much higher percentage of negroes in their population, such as Jacksonville, Florida, 57.1 per cent; Charleston, South Carolina, 56.5 per cent; Savannah, Georgia, 51.8 per cent. On the whole, however, it will be seen that the mass of the negroes in the United States still live in rural districts, although directly after the Civil War and again within recent years there has been a considerable movement of the negroes to the cities. This is extremely significant for the social conditions of the race, because the negro, while not adapted in general to the environment of civilization, is still less adapted to the environment which the modern city affords him. The Social Condition of the Negroes in the United States.--(1) _Intermixture of Races._ Ever since the negro came to this country he has been having his racial characteristics modified by the infusion of white blood. The census of 1890 attempted to make an estimate of the number of negroes of mixed blood in the United States. The number returned as being of mixed blood was 1,132,000, but all authorities agree that this number understates the actual number. The census officials themselves repudiated these figures as being entirely misleading. Experts in ethnology have estimated that from one third to one half of the negroes in the United States show traces of white intermixture. The lower estimate, that one third of the negroes of the United States have more or less white blood, is quite generally accepted by those who have carefully investigated the matter. Of course the proportion of negroes of mixed blood varies greatly in different localities. In communities in the border states frequently more than one half of the negroes show marked traces of white intermixture. But in the isolated rural regions of the South, where the negroes predominate, the full-blood negro is by far the more common type.
