It is not an easy task to update a census database by adding the data of the most recent survey since many changes have been made to the new survey according to the various changes of the social circumstances. For the electric data of the Fishery Census, the fishery areas and the survav items have been changed over the surveys. We therefore had to maintain the method to compare different surveys of the Census by keeping track of those changes of the fishery areas and survey items. We had designed a comparison scheme for our database of the 6 -10th Census and by using it we added the 11th Census data to our database. In this paper, we describe the update of our database and argue new points which arose because of the new features of the 11th data and the developments of the computing environments.
