Method of estimation is comprised by 4 steps. STEP 1 : Average and variance of tatami units of dwelling rooms of households members are estimated. STEP 2 : Distribution curve of tatami units of dwelling rooms is estimated by average and variance STEP 3 : Linear reggression models of average and variance are made, and average and variance in 2000 are estimated. STEP 4 : Distribution curve of tatami units of dwelling rooms in 2000 is estimated, and households is multiplied by the curue.
