Dealing with Big Data in
the context of Official Statistics requires considering complexity of using Big
Data in governing perspectives. The kind of knowledge is twofold:

knowledge able to enrich the traditional
statistics in order to make them more timely and differentiated from the
territorial and/or social point of view (e.g., nowcasting)

knowledge to be added to the traditional
statistics by observing phenomena from different angles through an ex-post

Both approaches may have
deep consequences in Official Statistics, in terms of challenges,
opportunities, needs and risks.
