Population scientists are generally developing mathematical models/techniques in demography and trying to provide brief explanation of extensive data sets. The prime objective of the present paper is to suggest a probability model to illustrate the distribution of female’s age at first menstrual onset. Menarcheal age distribution is used to evaluate risk associated to reproductive issues and may be used as a demographic indicator of female fecundity. The suitability of the model suggested is tested with the real data sets. Parameters of the model have been estimated through least square estimation technique. It is observed that older female’s age at menarche is somewhat higher than the younger female’s age at menarche. Also, a life table for menarcheal age using a probability model has been constructed. This life table will enable providing the expected duration of getting menarche for a girl of a particular age.
