title: [A model of structural transition based on the molecular-type population structure theorem].
abstract: The author presents a model of structural transition based on a theorem of molecular-type population structure.  "Household or family has been sometimes called [a] demographic molecule, when compared with the unit of ordinary population, i.e., a person, which in turn [is called a] demographic atom.  Molecular population structure is defined by the author as the age structure of the population composed of people included in certain [sorts] of molecules.  The molecular age structure is basically represented by matrices whose elements...are the numbers of people aged i whose other member person in the same molecule, for example mother, is aged j."
