STS571 Ossi Nurmi et al.
By recalibrating the existing survey data using data from MNOs, it’s
possible to combine the strengths and alleviate the weaknesses in both data
sources. This results in significant improvement in geographical as well as
temporal granularity of outbound tourism statistics. Geographical granularity
refers to the number of countries that can be reported, while the temporal
granularity is the monthly tourism seasonality to each of those countries.
This study was conducted by using data from two MNOs consisting of
roughly two thirds of all Finnish mobile subscribers. The data from both
operators are highly correlated. This suggests that similar results could be
obtained by using data only from a single MNO, given that its subscribers are
not geographically or socio-demographically biased.
