[63] The death-rate to which I particularly refer in the text, and which I cited in my last year’s report, is that of a large district in Northumberland, numbering 27,628 inhabitants, where, during the seven years 1838-44, the mortality was at the rate of only 14 _per_ thousand _per annum_; and even in this comparatively low proportion a very distinct share might still be called preventable deaths. It is not to the City alone of metropolitan districts that this high mortality belongs. Unhappily it affects the entire Metropolis; and we may find other towns in England, and still more on the Continent, where the death-rate is higher than under your jurisdiction. Yet your Hon. Court will not doubt that the standard to be adopted for your estimate of healthiness ought to be the lowest known death-rate; that every avoidable death represents an evil to society; and that, if a mortality of 12, or 13, or 14 _per_ thousand _per annum_ can be reached for one mixed population, there is ample room for discontent among any other population, which finds itself doomed to perish at double the rate of the first. * * * * * 3. In the third table[64] all the deaths of the last three years are enumerated in a form which may enable you to compare one year with another, and one sub-district with another, in respect of their several contributions to the total mortality. [64] This information is now included in the Quinquennial Synopsis, _Appendix_, No. II. * * * * * 4. In the fourth table[65] are classified, according to the ages at which they occurred, 9476[66] deaths of the last three years. This table is arranged in a manner to display its results--(1) for each year separately, and (2) for each Union separately, in order that you may observe what local or annual differences have obtained as to the ages of chief mortality. You will notice that in 3469 instances, nearly three-eighths of the whole, death has befallen children under five years old. Children at this age constitute about a tenth part of the population of the City. They accordingly die at about four times the rate which would fall to them as equal participators in the average mortality of the district. The next table will throw some light on this disproportionate excess of infant deaths. [65] Now embodied in Table VIII. [66] In the remaining number (17) the particulars of age and residence could not be correctly ascertained. * * * * * 5. In it[67] an enumeration is made of such deaths, during the last three years, as have arisen in consequence of acute disease partially or entirely preventable. They amount to 3923--more than two-fifths of the entire mortality of the period. [67] _Appendix_, No. IX. includes this Table. I would especially beg the attention of your Hon. Court to the particulars set forth in the successive columns of this table.
