Resumo(s)
The goal of any NSI is its ability to produce accurate, timely, reliable, and trusted official statistics.
Historically, NSIs have relied solely on data collected from traditional data sources such as surveys and
administrative data to compile official statistics. The dawn of big data is one that is expected to have
a huge impact on organisationssuch as National Statistical Institutions (NSIs). The purpose of thisstudy
is to conduct a quantitative science study on the evolution of topics in the field of big data sources in
the compilation of official statistics. The study will try to identify the evolution of topics in the research
of big data sources in the compilation of official statistics, to identify which country(s) have made the
most contributions to this research field, and to uncover emerging and relevant topics related to this
field. It was concluded that, big data sources such as scanner data, mobile phone data, sensor data,
and transactional data have been used institutions such as Statistics Netherlands, Bank Estonia, Italian
National Institute of Statistics, US Census Bureau, and the Spanish National Institute of Statistics.
Scanner data did seem to be the one big data source that has been used by a few institutions for the
compilation of the Consumer Price Index (CPI). The study identified some of the key topics relating to
big data and official statistics. Big data, officialstatistics, nowcasting, machine learning are some of the
common keywords that have been covered in this research field. When analysing the bi-gram (twowords) of the most commonly found abstract words, emerging and relevant topics include web
scraping, official statistics, data sources, and data governance.
