On the Relation of the Carlisle Table to the Government, the Registrar-General's and other Tables of Mortality

Extract

The paper commenced with a general view of the effect of emigration upon returns of deaths among the population of England and Wales, followed by an estimate of the extent to which any calculations based upon such returns, and the general census, must be thereby affected. This was followed up by some remarks on the uncertainty attending the statements of ages of the individuals enumerated in the census returns, and the ages returned as at death. A tabular view of the estimated effect of these causes of error upon the expectation of life, derived from the returns, was also given.
