What are mobility indicators?
Indicators are generated by processing anonymised and aggregated CDR data to adjust for variation in mobile network activity (i.e. changes in the frequency with which subscribers use their mobile phones) and to combine with other data (e.g. baseline values from a reference period) to provide more nuanced descriptions of population distributions and mobility. Indicators may also be adjusted to address representativeness biases and scaled to the size of the population.
