This study validates the significance of the abilities required by older workers to carry out their job responsibilities effectively, and secondly, offers a clearer understanding of how age-related declining manifests based on the specific abilities essential for each occupation. To achieve this objective, we utilized O*NET data and conducted the following research process. Firstly, the susceptibility index, SI, was recalibrated by taking into account the relative importance of different abilities. Secondly, occupations were categorized based on their SI index, thereby allowing for a comparison of job characteristics within the dataset. Lastly, the latent class analysis method was employed to examine the pattern of SI across various ‘ability groups.’ One of the crucial findings from this research is the necessity to comprehend the decline in abilities within specific ability groups, such as cognitive or sensory abilities. The study also identified distinct clusters, such as white-collar and blue-collar groups, and a group with white-collar attributes but exhibiting a somewhat similar level of decline as the blue-collar group. The implications of this study extend to the broader utilization of national data and its potential to contribute significantly to future research concerning the prediction of ability decline and early retirement.
