The figures C were obtained from only one Department--the Local Government Board. (In case the meaning of this table is not at once clear, it may be explained that the first line, for instance, means that for 100s. expended on food by the wage-earning households in June, 1922, exactly the same quantities and exactly the same foods could, according to the Post Office officials' returns, be purchased in March, 1922, for 104.8s., and in July, 1914, for 52.4s. and according to the other returns for 102.8s. and 54.6s. respectively; and so on with the other items). The near agreement of these figures is a strong proof of their essential accuracy. We ultimately decided to take the average between the two sets of figures as representing the nearest approach to the truth at which we could arrive. (B) The Collection of Household Budgets. (1) _Representative Budgets._ The second stage of our enquiry was to obtain representative household budgets, from which to compile the "weights" by which the individual price changes might be combined into a single final figure. For this purpose a special Form was drafted (Form B6, a copy of which appears in the Appendix) and some 5,000 of these forms were despatched to National School teachers in every school in the country, accompanied by detailed instructions (of which there is a copy in the Appendix) of the method in which they were to be completed. Notwithstanding the difficulties of the time when these budgets were called for, and the fact that a number of forms were held up and perhaps lost in the post, we were able to use 308 completed budgets of wage-earning households, received from 112 towns. This number was quite sufficient for our purpose. These budgets were excellently filled in, and, apart from the fact that such a number is in itself a fair guarantee of the statistical results obtained, we are satisfied for reasons given below of the substantial accuracy of the budgets.
