Abstract

The study analyses the regions’ economic activity in Latvia using Latvia Mobile Telephone (LMT) mobile communication data from July 2015 to January 2017. The call activity and a number of unique phone users by 119 Latvia counties and biggest cities were analysed in two steps: at first method of principal components was used to explain the variance in the data and then exploratory factor analysis was applied. Three factors were identified that describe 87.5% of the total variance of the aggregated daily data. The first factor is related more to the regions with higher economic activity, the second and third factors capture, respectively, lowers call activity during weekdays and are related to the regions with lower economic activity in total. When to look at the same data but aggregated not only by day but also by daytime, then there are two new factors that describe 94.8% of the total variance. One of the factors is related to higher economic activity in regions as has higher values during normal working hours and lower values after working time, the second is related to the regions with lower economic activity. So it was concluded that during normal working hours the economic activity is higher in the regions with higher call activity. As the result considered indicators of call activities and unique phone users can be used for the identification of the regions with similar economic activity patterns.
