In the reslationship between the mean age at menarche and the level of meanarche experience rate of the subject, the subject of study with higher menarche experience were more likely to be higher mean age at menarche than those with lower menarche experience rates. In case of menarcheal experience rates at 75-90 percent among the subjcet, the values of mode and median ere more close to the actual mean age at menarche under the assumption that all of the subject had experience menarche.
4. The trends of age at menarche during 1935-92 were linear decrement : Y=85.93-0.036X in the whole country and Y=91.35-0.039X in Seoul. The rates of secular diminution in age at menarche calculated to be about 4.3 months per decade in the nation-wide, and 4.6 months in Seoul during the periods.
