APPENDIX.
STATISTICS BEARING ON THE TENEMENT PROBLEM.
Statistics of population were left out of the text in the hope that the results of this year's census would be available as a basis for calculation before the book went to press. They are now at hand, but their correctness is disputed. The statisticians of the Health Department claim that New York's population has been underestimated a hundred thousand at least, and they appear to have the best of the argument. A re-count is called for, and the printer will not wait. Such statistics as follow have been based on the Health Department estimates, except where the census source is given. The extent of the quarrel of official figures may be judged from this one fact, that the ordinarily conservative and careful calculations of the Sanitary Bureau make the death-rate of New York, in 1889, 25.19 for the thousand of a population of 1,575,073, while the census would make it 26.76 in a population of 1,482,273.
