PROBLEM TO BE SOLVED: To provide a system for displaying an exact walking age on the basis of the measurement of walking behavior.SOLUTION: A walking age display system for displaying an age (walking age) corresponding to the ability to walk on the basis of the measurement of walking behavior which includes: footprint measurement means 2 for outputting walking parameters based on the measurement of at least the distance or the angle of footprints； acceleration measurement means 10 which is carried by a subject and outputs walking parameters based on the measurement of the acceleration during walking； overall walking age calculation means (personal computer 3) for outputting an overall walking age based on the walking parameters outputted from the footprint measurement means 2 and the walking parameters outputted from the acceleration measurement means 10； and display means (display 4) for displaying the overall walking age outputted from the overall walking age calculation means.
