Abstract:
The purpose of this core is to develop and direct sampling strategies for the Program Project. The target population for this project is defined as consisting of all individuals who reach their 100th birthday by the end of the year 2003 and, who at the time they are first contacted, reside within a geographic area defined by 44 counties of Georgia. The Sampling and Subject Ascertainment Core is responsible for sampling individuals from both community-dwelling and institutional settings according to census estimates. Four distinct samples, of sufficient total size to provide 242 centenarians who complete the full complement of five data collection sessions, will be selected from that population and passed on to the Recruitment and Data Acquisition Core. In addition, control samples will be developed of individuals in each of six age groups ranging from 20 to 59 years for Project 1. Samples of those age 65-69 and 80-89 will be obtained for Projects 3 and 4. A list of telephone numbers will be developed, using random digit dialing procedures, in sufficient numbers to provide control samples of 100 respondents living within the same geographic area and in each of the age ranges 20-29, 30-39, 40-49, and 50-59.
