Summarizing our results, it is seen that police arrests, jail, workhouse and penitentiary commitments appear to have increased during the period from 1890 to 1892-1896. The highest rates of arrests and commitments were about 1893. Since 1894-1896 the tendency of both arrests and commitments to decrease has been notable. The crime-rate for murder is also probably decreasing. It appears, therefore, that the conclusion that crime is probably decreasing among the Negroes of the United States is warranted. The crime-rate of Negroes, North and South, appears at present to be about the same, although the rate of police arrests for some Southern cities is higher than that for the Northern cities. The claim that there is greater criminality among the Negroes of the North than those of the South is probably not true. The fallacy on which this claim was based was in comparing the criminal rate of the Negroes of the North, who live almost entirely in cities, with the criminal rate of the Negroes of the entire South, the great majority of whom live in rural communities.

Besides, differences in age-grouping are usually ignored.

On the whole, therefore, there is firm ground for hope as the Negro becomes adjusted to the urban environment.

Since, then, these economic and social causes bid fair to continue their influence for an indefinite time, the concentration of Negroes in urban centers makes imperative the need of knowledge and methods of dealing with the problems that face the Negro and the Nation in these growing urban centers[29]. These questions of how to live in the city are problems of health, of intelligence and of morals. They are economic, social, political, educational and religious. The present essay is an attempt to study carefully the economic problems arising out of the Negro's adjustment in his struggles to make a living and to live in the city as seen in the commercial Metropolis of America; to find out at what he is employed there; to inquire of his efficiency and success, and of the attitude of employer and fellow employee. As we find Negroes rising from the plane of the employed to that of the employer, these questions arise: How does he get into business and what lines does he enter? With what success does he meet? What resourcefulness does he show? What are the reasons for his failures? We want to know what are his relations with the business world with which he deals and the consuming public to whom he caters. These and many other things can be ascertained only by painstaking investigation.

This study aims to be a small contribution to the end that efforts for betterment of urban conditions may be founded upon facts. The material has been treated in two parts—that relating to wage-earners and to business undertakings. In the former the United States Census reports, a personal canvass, and the unpublished schedules for 2,500 families of the New York State Census of 1905, were used as sources; for the latter a block to block canvass was made and records of the business enterprises were secured by personal interviews.

FOOT-NOTE ON THE MANNER AND CAUSES OF CITY CONCENTRATION OF POPULATION[30]

The manner of growth has been two-fold: (1) By natural increase through the lowering of the death-rate due partially to improved housing conditions, progress in personal hygiene of the poorer classes and in city sanitation and inspection; (2) by migration: that is, short distance movements by progressive stages from the more rural districts toward the larger centers.[31] In the case of the great cities this may mean increase in density of the most populated areas.[32]

The causes of concentration in cities are the following:

I. The Divorce of Men from the Soil.[33] The diminishing relative importance of elementary wants, improvements in scientific cultivation and in agricultural machinery, and the opening of distant and virgin fields by better transportation have reduced the relative number of workers needed on the soil.

II. The Growth of Commercial Centers.[34] This went hand in hand with the Agrarian Revolution. Trade has been the basis of city founding. The prevailing influence in determining location has been "a break in transportation." Where goods are transferred and where, in addition, ownership changes hands, urban centers grow up. Wealthy classes arise which require others to supply their increasing and varied wants.
