A system and method are provided for using demographic data to derive a PWV-BP transform. The method provides a PWV measurement device with a non-transitory memory, processor, and a calibration application for supplying pseudo-calibrated PWV values. The method loads into the memory a first database of information cross-referencing age compared to central-aortic PWV-BP transforms, a second database of information cross-referencing age and gender compared to systolic and diastolic blood pressure, and a third database of information cross-referencing age as compared to whole-arm PWV. Whole-arm PWV measures a distance between a superasternal notch and index finger, divided by a transit time of an arterial pulse from to heart to the index finger tip. After accepting age and gender data from a first user, the calibration application interpolates the information from the first, second, and third databases, and derives a pseudo-calibrated whole-arm PWV-BP transform for the first user.
