This research report is the first of a three-part series aimed at developing a greater understanding of older adults and their use of Individual Development Accounts (IDAs). The intent of this first report is to answer the following three questions: 1) Who are the older adults participating in IDAs? 2) What are they saving for? and 3) What do we know about IDAs and saving for retirement? These questions are answered using data from the American Dream Demonstration (ADD), the first nation-wide evaluation of IDAs as tools for asset building and community development. In this report, comparisons are made between older (50 years or older) and younger (49 years or younger) adults for the purpose of identifying variations in IDA participation by age.
