It now only remained for us to compile the final figure.
This was ascertained by multiplying the ratio prices of the various commodities by the "weights" appropriate to those commodities (i.e., by multiplying the figures in the first six columns of the table above by the figures in the final column).
The following table gives the result so obtained:—
| Mid-July, 1914. | Mid-March,1922. | Mid-June, 1922. | ||||
| A. | B. | A. | B. | A. | B. | |
| Food | 2992.0 | 3117.7 | 5984.1 | 5869.9 | 5710.0 | 5710.0 |
| Clothing | 922.3 | 925.7 | 1818.2 | 1779.7 | 1750.0 | 1750.0 |
| Rent (C) | 426.1 | 426.1 | 542.2 | 542.2 | 540.0 | 540.0 |
| Fuel and Light | 326.2 | 336.7 | 730.8 | 730.8 | 700.0 | 700.0 |
| Sundries | 657.0 | 674.7 | 1341.6 | 1327.3 | 1300.0 | 1300.0 |
| Total | 5232.6 | 5480.9 | 10416.9 | 10249.9 | 10000.0 | 10000.0 |
Then, taking the prices in July, 1914, as the standard and representing them by the figure of 100 we get the final percentage table.
| Mid-July, 1914. | Mid-March,1922. | Mid-June, 1922. | ||||
| As Per Cent. of | A. | B. | A. | B. | A. | B. |
| July, 1914. | 100 | 100 | 195.7 | 187.0 | 187.8 | 182.5 |
The following table shows the percentage changes so obtained for the main groups of commodities:—
| March 1922 over July, 1914. | June 1922 over July 1914. | |||
| A. | B. | A. | B. | |
| Food | 99.9 | 88.3 | 90.8 | 83.2 |
| Clothing | 97.3 | 92.0 | 89.9 | 88.7 |
| Rent (C) | 27.3 | 27.3 | 26.8 | 26.8 |
| Fuel and Light | 124.9 | 117.2 | 114.6 | 108.0 |
| Sundries | 104.1 | 96.9 | 97.8 | 92.8 |
| All Items | 95.7 | 87.0 | 87.8 | 82.5 |
The figures in column marked "A" as before were obtained from the prices collected by Post Office officials, and those marked "B" from prices collected by officials of the Ministry of Labour and Local Government Board.
By taking the mean of "A" and "B" for March and for June, 1922, the final figures showing the increases in the Cost of Living are obtained:—
