| Summary: | The Leslie matrix model uses matrices in projecting the population at any future time. The basic system involved is that an arbitrary age distribution may be operated on by a square matrix, under given conditions, of which the first row essentially represents the age-specific fertility while the principal subdiagonal is a measure of survivorship. All other elements of the basic matrix are zeroes. By repeated post multipliation by this matrix, one can calculate the population size and age distribution in the future from an existing one. On this study, the authors are concerned with presenting the theory as well as applying the concepts in the island-province of Siquijor. Values are computed through a BASIC computer program which includes the only real and positive eigenvalue 1 that corresponds to the finite rate of increase and its eigenvector that represents the stable age distribution. The study yields the conclusion that the population of Siquijor is young and that this will remain to be so for subsequent years. Hence program planners should give more attention to this particular group of the populace. |
