This research is concerned with methods for calculating target amounts for in-home and institutional services for the elderly with senile dementia, a rather narrow field, but for whom service demands are widespreadly held to be difficult to measure. Specifically, we will put forward considerations based on the comparison and arrangement of data from the results of a survey on the elderly with senile dementia living in their own homes in Sendai City, which our centre has used in previous research, and legal formulas for calculations in official government health and welfare plans for the elderly. Items to be dealt with are as follows; (1) Measuring the number of people requiring the services (2) Minimum service standards (3) Necessary degree of services (4) Service target amounts
