Making allowance for some families of professional and business classes, probably not excluded from the Census figures for 1900, and for changes which five years interval may have caused, the agreement with the two preceding tables above confirms the representative character of the data for 1905 and 1909. For the total per cent under fifteen years in 1900 was 19.8; in 1905, 19.0; from fifteen to twenty-four years, 24 per cent in 1900, 21.9 per cent in 1905; from twenty-five to thirty-four years, 25.9 per cent in 1900, 31.6 per cent in 1905; from thirty-five to forty-four years, 16.2 per cent in 1900, 17.3 per cent in 1905; from forty-five to fifty-four years, 8.3 per cent in 1900, 6.6 per cent in 1905, and fifty-five years and over, 5.6 per cent in 1900, 3.2 per cent in 1905.[45] Here, then, is a wage-earning group made up of persons in the younger and more vigorous working period. The small number of children under 15 years of age calls attention to the fact that the growth of this population takes place largely through recruits from other sections of the Country. They must find industrial and social adjustment to a new environment largely made up of the white population. They are either killed off by the conditions under which they work and live, or drift away from the city at a premature old age. 2. NATIVITY OF NEGRO WAGE-EARNERS
