In 2006, the United States Congress passed the Pandemic All-Hazards Preparedness Act (PAHPA) which mandated that all emergency preparedness planning shall address at-risk populations. Further, in 2013, the reauthorization of this act, known as PAHPRA, defined at-risk individuals as "children, older adults, pregnant women, and individuals who may need additional response assistance." This vague definition leaves emergency managers, planners, and public health officials with the difficult task of understanding what it means to be at-risk. Further, once identified, the geographic location of at-risk individuals must be obtained. This research first uses the concept of social vulnerability to enhance the understanding of what it means to be "at-risk." Then, by comparing two data disaggregation techniques, areal weighted interpolation and dasymetric mapping, I demonstrate how error of estimation is affected by different scenarios of population distribution and service area overlap. The results extend an existing framework of vulnerability by stratifying factors into quantifiable and subjective types. Also, dasymetric mapping was shown to be a superior technique of data disaggregation compared to areal weighted interpolation. However, the difference in error estimates is low, 5 percent or less in 72 percent of the test cases. Only through local collaboration with community entities can emergency planners access the appropriate data to both: 1) understand the nature of at-risk individuals in their service areas and 2) spatially target resources needed to ensure all individuals are planned for in case of a bio-emergency.

The concept of population ageing is a development issue that has received much attention due to the demographic transition that is occurring globally, marked by declining levels of fertility and mortality. Therefore, the implications of population ageing for older persons within the context of Social Development was examined from the perspective of government and non government officials. The study was confined to older persons and the policies and programmes implemented by the Department of Social Development. The study employed an exploratory research design within a qualitative paradigm. Semi-structured interviews and a questionnaire were distributed to officials in the nine provinces. Thirty six questionnaires were received and qualitative methods of data analysis were used to analyse and interpret the data. The main finding of the study is that there is congruence in what government officials and the non government officials view as implications for older persons. Central to this is that the issue of ageing does not receive attention on the agenda of government. The top five priorities for older persons are healthy ageing, economic security, community/home based care services for older persons, having care and support systems for older persons and an improved quality of life/poverty alleviation. Based on the demographic determinants of population ageing, the findings are that there will be an increased demand for services for older persons which might place a strain on the social assistance and health care programmes. The issue of ageing was viewed positively as an opportunity by government officials and pessimistically as a challenge by NGO’s. The most common problems in old age is a reliance on the younger generation and or the state for their care and support, abuse, high levels of illiteracy and the burden of care for their children and grandchildren. The future older person is likely to be in better health and better educated than the older person of today if the necessary public investments are made now in these areas. The study makes recommendations for the adoption of a South African plan of action on ageing, inter-sectoral budgeting, development of specialised programmes, review of current policies and legislation for older persons, strengthening the partnership with the NGO sector and facilitating ageing mainstreaming within government programmes. / Sociology / M.A. (Social Development)
