Details
Mobility
The mobility indices Within and Exits has been obtain as ratio of the total number of weekly travels in reference to the total number of travels in the week of reference (week0).
In particular,
Within = \frac{\textnormal{Number of travels within the province 'indiv' in the week 'time'}} {\textnormal{Number of travels within the province 'indiv' in the reference week (week0)}}
Exits = \frac{ \textnormal{Number of travels with origin in the province 'indiv' and arrival to another province in the week 'time'} } { \textnormal{Number of travels with origin in the province 'indiv' and arrival to another province in the reference week (week0)} }
A ‘travel’ is a displacement from an origin to a destination of at least 500m. A travel can have several stages. These stages of the same travel are calculated based on the duration of the intermediate stop. For example , if I move from origin A to destination B with a stop at a point C of long duration, it is considered two travels, but if the stop is short, it is considered a single travel. For example, I can go by train from Madrid to Alicante, and there takes a bus to Benidorm. The travel will be one (Madrid-Benidorm). If I do the same but the stop in Alicante is long (or an overnight stay, for example), two travels will be considered (Madrid-Alicante, and Alicante-Benidorm). Similarly, if I go by car from Madrid to Alicante and stop for 15 minutes to take a coffee, it is also considered only one travel and not two. The travels considered in this study are always from 500m, due to the limitation of source data that is based on mobile telephony and its antennas. But one travel can be 600 meters or 600km.
Incidence
Incidence = \log \left( \frac{ \textnormal{total diagnostic cases of COVID-19, PCR test in the week 'time' at the province 'indiv'} } {\textnormal{total population in the province 'indiv'}} \right)
Essential activities
Essential activities. Economic activities whose activities are essential for the population. By example, essential activities are healthcare, food supply, State security, media and communication, refuse collection, management and public transport, etc. Non essential activities are by example, restaurants, hotels, hairdressers, etc. A full list in the Spanish official bulletin
