From the Document: "The Older Americans Act (OAA) of 1965 was enacted, among other things, to help older adults remain in their homes and communities. Programs authorized and funded by OAA Title III grants provide a broad range of assistance to older adults in need of such services, including congregate and home-delivered meals, home-based care, and transportation services. […] The GAO [Government Accountability Office]examined what is known about older Americans' reported need for home and community-based services like those funded by the OAA and the potential unmet need for these services, based on national survey data. GAO's methodology is consistent with the methodology it used for its 2011 report. Specifically, to estimate likely need and receipt of meals services like those funded by Title III programs, GAO analyzed the most recent data from the CPS Food Security Supplement (2013). GAO estimated likely need for meals services by examining the percentages of low-income older adults who were food insecure, using the U.S. Department of Agriculture's measure of food insecurity, or had one or more types of functional impairments that may make it difficult to obtain or prepare meals. To estimate likely need and receipt of home-based care, GAO analyzed the most recent data from HRS (2012) on whether respondents of all incomes age 60 and older reported having difficulty with one or more daily activities and whether they received help. Finally, to estimate potential need for transportation services, GAO analyzed HRS data on driving capabilities and car access for respondents of all incomes age 65 and older."
