    ages. For females at all ages except from 5 to 15, the death-rate is lower than for males. From the above statement it will be clear that a considerable excess of women (as in a residential district with a large number of domestic servants) or a considerable excess of either sex at the ages of 15 to 45 (as in most large towns) in proportion to the number living at other ages, would produce a lower total or crude death-rate, which does not imply any truly more healthy condition than that of another district, which is less favourably constituted so far as the proportion of the sexes and the numbers living at different ages are concerned. By a means of correction now to be described this source of error can be eliminated. The method of obtaining the factor fov correction can be best understood by an example. The annual death-rate of England and Wales in 1881-90 was 19*15, and the death-rate at each age-group is given in the following table: MEAN ANNUAL DEATH-RATE IN ENGLAND AND WALES, POPULATION CALCULATED AGES. 1881-90, PER 1,000 LIVING AT OF HUDDERSFIELD IN i8qi.

The total number of deaths thus calculated is 1572 in a population of 95,420, and the total death- rate = 16'47 per 1000. This is the standard death-rate, i.e., the death-rate at all ages calculated on the hypothesis that the rates at each of 12 age-periods in Huddersfield were the same as in England and Wales during the ten years of the last intercensal period, viz. 19-15 in 1881-90.* But the standard death-rate of Huddersfield ^ This was written before the figures for the period 1891-1900 were available ; but the method adopted is the same, substituting the death-rates, etc., for the later period.
