What is the best way to take internet usage into consideration in the different variants of the active ageing index?

Summary/Abstract: The paper provides a brief description of the Active Ageing Index (AAI). This indicator, introduced in 2012, aims to measure the potential of older people for active and healthy ageing. The indicator is constructed from European Union survey data, and these results are weighted with coefficients determined by experts. One of the variables from the surveys measures the proportion of older people using the internet at least once a week. We argue that such regular internet usage does not show too much variation in this era of the ubiquitous internet, so a more sophisticated definition of internet usage must be taken into consideration. Our discussion contains three different AAI variants: the original expert-based, the Djurovic et al. (2017) I-distance indicator, and our factor-based index.
