Aging rates of a sample which should represent the total population li
ving in a district of Madrid were studied using the vectorial calculat
ion as a mathematical model. The number of individuals who finally par
ticipated was 867, homogeneously distributed by sex and age decades in
the age range of 20-100 years. A total of 15 variables was applied, b
ut they were deduced from health-related data obtained from a special
elaborated questionnaire. The resulting aging factor - a dimension to
evaluate the aging acceleration - agrees with the corresponding result
s of biological aging studies previously published. Moreover, we conte
nd that the obtained information from the simply sent questionnaire is
accurate and of biological value, and would enable studies on the agi
ng rates of populations.
