The statistical analysis methods employed are to include: • Frequency analysis and analysis of variance, depicted with histograms and box plots, portrays the distribution of the different age groups within the world population. This study provides a baseline for comparing the distribution of the different age groups for each of the defined income aggregates to each other. • Scatter diagrams provide visualizations, based on all the data points available, of the relationships between per capita GNI and the percentage of population in the three different age groups. • Bivariate liner regression develops these regression lines, along with their coefficient of determination, for each pair of variables, providing a visualization depicting trends …show more content…
Based purely on secondary sources consisting of authoritative literature, this will be a theoretical effort with the objective, not to seek out causal links, but to inspire thought and drive future research into socioeconomic issues related to older populations and through inference, developed economies. These are issues faced currently by developed economies and will affect developing economies as they progress. Such issues, if not dealt with, may lead to economic …show more content…
White and Marsh (2006) described content analysis as a methodical and rigorous technique to analyzing literature during research. The pool of available literature is extremely broad, since these issues tend to cross the boundaries of numerous areas of study. To keep this effort practical, the selection of recent, authoritative, peer reviewed papers or articles will be limited to seven for inclusion. The primary sources for the second, qualitative effort, are ProQuest and EBSCOhost based on search terms such as ageing population, socioeconomic issues, immigration, healthcare, and social security and combinations of these search terms built with Boolean operators. Care is taken in the selection of literature to include discussions involving a range of nations and cultures. Attitudes towards older adults, work ethics, and numerous other social dimensions vary among the differing cultures found globally. These efforts at diversity are undertaken to avoid any hint of ethnocentrism. Although there may be specific social dimensions that either ease or worsen issues impacting advanced economies based on an older population, the objective of this research effort is to remain as general as possible and not focus on any one nation or
