Total , aggregate and sum , as here considered, mean a result, such as a figure or amount, arrived at by adding or putting together all parts or elements of a particular group or mass. They may or may not suggest that the result contains everything that should be in it. The membership of an organization may be a total of 150; attendance at a meeting of the organization may be a total of only 100. An aggregate of statistical samples does not cover the entire range of what is being examined; the aggregate of a person’s characteristics is a composite picture of the entire person. The sum of two or more figures is fixed and complete; the sum available for financing a project is merely what is on hand and not necessarily the sum needed.

Totality and whole indicate the same kind of result denoted by total, aggregate and sum , but here the result does contain all the parts or elements that should be in it. The totality of a nation’s productive capacity includes the sum , total or aggregate of all its natural resources, productive establishments, labour force and technical competence. The whole of a nation’s economy is the sum of the value and capability of all its component parts.
