Maasai - Age-sets. Introduction. The basic Maasai political and social structure is their rigid system of age-sets (or age grades; strictly-speaking, an age-grade is a stage within the age-set). These apply primarily to men; women automatically become members of the age-set of their husbands. Under this system, groups of the same age (give or take five years or so) are initiated into adult life during the same period. The age-set thus formed is a permanent grouping, and lasts throughout the life of its members.
The Actual Age is the number of years that have passed since the structure was built. Actual age is also called the Chronological Age. The Effective Age is the estimate of the age of a structure based on its utility and physical wear and tear. The effective age is the difference between the Economic Life of the structure and the Remaining Economic Life of the structure. The appraiser considers effective age in any appraisal.
