The factors ( 2) and (3) have been adopted as providing, in combination with population as proposed, an index of general needs and relative wealth and poverty. The factor of unemploy ment is only brought into operation as a further index of the need for assistance where the unemployment is abnormal. The last factor, which is applicable only to administrative counties other than London, has been adopted as a measure of the spread of the population over large areas. For the application of these
principles, for further details of the operation of the act, see the Explanatory Memorandum (Command Paper 3,273 of 1929) pre sented by the minister of health to parliament.
