The next most important element in that growth consists of (3,055) three thousand and fifty-five families who are to occupy 505 tenements, to be constructed at a cost of $2,629,026, the average investment to provide a home for each family in this case being $806, _plus_ the cost of the land. Allow one-third as before to this latter item, and the cost of each home becomes $1,075. Assume $120 to be the average rent asked for such dwelling places, and it would appear that these 3,055 families do not command an average income in excess of $450. These families form three-tenths of the City's growth for a year as foreseen by its builders. Thus, nine-tenths of the expected increase has been classified with a reasonable approximation to accuracy. The averages thus far submitted are not likely to be seriously misleading, since they represent varieties of construction and modes of life in which a uniform type is closely followed. Among those inhabitants composing the remaining tenth, incomes cover a wider range, but a comprehensive view even of these is by no means unprofitable. For 1,168 families the same number of private dwellings were built, costing $4,660,388, the average cost of each dwelling being $4,000. In order that these averages might not be misleading, the Commissioner of Buildings has, at my request, examined every permit issued by him during the year, and has arranged them upon certain suggestive bases of classification. This last group of 1,168 families includes no permits for private dwellings whose construction cost over $10,000. The average cost of dwellings costing less than $10,000 each, occupied by one family is, therefore, $4,000. While this figure represents the average cost of dwellings of this class, it would appear that the actual cost of the greater number of these dwellings was considerably less than the average. Otherwise the average would not have been drawn to a point so far below the maximum cost of $10,000. These 1,168 families may be safely assumed to stand upon lots worth one-third of their cost. Thus, these 1,168 dwellings are to dwell in homes representing an average investment of $5,333. Upon the basis of computation before employed the income of these families should average not far from $2,000 per year. In fact, for reasons just suggested, these incomes range from a minimum of $1,000 or less to a maximum rarely exceeding $5,000 or $6,000. And a greater number of these incomes undoubtedly falls below the average point of $2,000. Perhaps the greater number would be found to be not far from $1,500.
