The world has experienced a tremendous growth in its elderly population. With the aging of the population, policy makers are concerned about the health of these elderly as well as their utilization of health care and social services and perceived need for additional services. The Canadian elderly population is similar to other elderly populations in that a few tend to be the heaviest users of the available services. The predictors of this utilization behavior and perceived need primarily include need variables, such as the number of limitations of daily living -- both ADLs and IADLs, and functional limitations. In addition, enabling variables, such as income, work activity and geographic region of residence were also found to be significant.
