table gives the exact figures for each decade :
POPULATION OF PHILADELPHIA. 1790-1890.
INCREASE OF THE NEGRO POPULATION IN PHILADELPHIA FOR A CENTURY.
[NOTE.—Each horizontal line represents an increment of 2500 persons in population ; the upright lines represent the decades. The broken diagonal shows the course of Negro population, and the arrows above recall historic events previously referred to as influencing the increase of the Negroes. At the base of the upright lines is a figure giving the percentage which the Negro population formed of the total population.]
The Negro has never formed a very large percent of the population of the city, as this diagram shows:
PROPORTION OF NEGROES IN TOTAL POPULATION OF PHILADELPHIA.
A glance at these tables shows how much more sensitive the lower classes of a population are to great social changes than the rest of the group; prosperity brings abnormal increase, adversity, abnormal decrease in mere numbers, not to speak of other less easily measurable changes. Doubtless if we could divide the white population into social strata, we would find some classes whose characteristics corresponded in many respects to those of the Negro. Or to view the matter from the opposite standpoint we have here an opportunity of tracing the history and condition of a social class which peculiar circumstances have kept segregated and apart from the mass.
If we glance beyond Philadelphia and compare conditions as to increase of Negro population with the situation in the country at large we can make two interesting comparisons : the rate of increase in a large city compared with that in the country at large ; and the changes in the proportion of Negro inhabitants in the city and the United States.
INCREASE OF NEGROES IN THE UNITED STATES AND IN THE CITY OF PHILADELPHIA COMPARED.
A glance at the proportion of Negroes in Philadelphia and in the United States shows how largely the Negro problems are still problems of the country. (See diagram of the proportion of Negroes in the total population of Philadelphia and of the United States on opposite page.)
This is even more striking if we remember that Philadelphia ranks high in the absolute and relative number of its Negro inhabitants. For the ten largest cities in the United States we have :
TEN LARGEST CITIES IN THE UNITED STATES ARRANGED ACCORDING TO NEGRO POPULATION.
Of all the large cities in the United States, only three have a larger absolute Negro population than Philadelphia: Washington, New Orleans and Baltimore. We seldom realize that none of the great Southern cities, except the three mentioned, have a colored population approaching that of Philadelphia:
COLORED* POPULATION OF LARGE SOUTHERN CITIES.
Taken by itself, the Negro population of Philadelphia is no insignificant group of men, as the foregoing diagrams show. (See page 52.)
In other words, we are studying a group of people the size of the capital of Pennsylvania in 1890, and as large as Philadelphia itself in 1800.
Scanning this population more carefully, the first thing that strikes one is the unusual excess of females. This fact, which is true of all Negro urban populations, has not often been noticed, and has not been given its true weight as a social phenomenon.2 If we take the ten cities having the greatest Negro populations, we have this table :3
COLORED* POPULATION OF TEN CITIES BY SEX.
This is a very marked excess and has far-reaching effects. In Philadelphia this excess can be traced back some years :
PHILADELPHIA NEGROS BY SEX.4
The cause of this excess is easy to explain. From the beginning the industrial opportunities of Negro women in cities have been far greater than those of men, through their large employment in domestic service. At the same time the restriction of employments open to Negroes, which perhaps reached a climax in 1830–1840, and which still plays a great part, has served to limit the number of men. The proportion, therefore, of men to women is a rough index of the industrial opportunities of the Negro. At first there was a large amount of work for all, and the Negro servants and laborers and artisans poured into the city. This lasted up until about 1820, and at that time we find the number of the sexes approaching equality in the county, although naturally more unequal in the city proper. In the next two decades the opportunities for work were greatly restricted for the men, while at the same time, through the growth of the city, the demand for female servants increased, so that in 1840 we have about seven women to every five men in the county, and sixteen to every five in the city. Industrial opportunities for men then gradually increased largely through the growth of the city, the development of new callings for Negroes and the increased demand for male servants in public and private. Nevertheless the disproportion still indicates an unhealthy condition, and its effects are seen in a large percent of illegitimate births, and an unhealthy tone in much of the social intercourse among the middle class of the Negro population.5
Looking now at the age structure of the Negroes, we notice the disproportionate number of young persons, that is, women between eighteen and thirty and men between twenty and thirty-five. The colored population of Philadelphia contains an abnormal number of young untrained persons at the most impressionable age ; at the age when, as statistics of the world show, the most crime is committed, when sexual excess is more frequent, and when there has not been developed fully the feeling of responsibility and personal worth. This excess is more striking in recent years than formerly, although full statistics are not available:
This table is too meagre to be conclusive, but it is probable that while the age structure of the Negro urban population in 1848 was about normal, it has greatly changed in recent years. Detailed statistics for 1890 make this plainer :
NEGROS* OF PHILADELPHIA BY SEX AND AGE, 1890
Comparing this with the age structure of other groups we have this table :6
In few large cities does the age structure approach the abnormal condition here presented ; the most obvious comparison would be with the age structure of the whites of Philadelphia, for 1890, which may be thus represented :
