Methodological issues. Big Data can be used in several ways when producing official statistics. It can be used as the main source of information, as an additional data source to aid estimates primarily based on survey or administrative data or merely to improve the weights in model-based estimation or to impute missing values. In all cases the methods used may differ. As a consequence, each of the issues described below could be interpreted from these different points of view. It was therefore decided to consider the experiences in WPs 1 to 7 of the ESSnet as the starting point for the focus of each section. Hence, the focus is on methodology when using Big Data in practice. The experience gained here, forms the basis of a -to be developed- general applicable Big Data methodology. 2.1. What should our final product look like?
