How many graves are necessary in the near future? This is one of the basic concerns in the process of city planning; hence cemeteries are the important public facilities. In the past several years, many surveys on graves have been made in order to estimate the demand of graves. However, it is very difficult to get the homogeneous samples from the population by questionnaires. This is because the interests in graves are varied according to their family- or dwelling-types. In this paper we propose a method to reduce this difficulty and estimate the spatial distribution of demand on graves by using urban lattice data. The locality and some other findings are shown in a case study on Kanagawa Prefecture.
