E-Mail A huge volume of digital data has been harvested, stored and shared in the last few years - from sources such as social media, geolocation systems and aerial images from drones and satellites - giving researchers many new ways to study information and decrypt our world. In Switzerland, the Federal Statistical Office (FSO) has taken an interest in the big data revolution and the possibilities it offers to generate predictive statistics for the benefit of society. Conventional methods such as censuses and surveys remain the benchmark for generating socio-economic indicators at the municipal, cantonal and national levels. But these methods can now be supplemented with secondary, mostly pre-existing data, from sources such as cell-phone subscriptions and credit cards. According to the FSO's 2017 Data Innovation Strategy, "The goal of data innovation is to enhance the quality, scope and cost-efficiency of statistical products and to reduce the response burden on households and businesses."
