A detailed database of sub-annual Spanish demographic statistics: 2005-2021

The big data revolution has made it possible to collect, transmit and exploit huge amounts of data. The potential this offer for data analysis, however, clashes with the limitations imposed by laws on protection of personal data. This paper details a new database (DEMOSPA0521) made after processing and summarising more than 868 million demographic records from Spain, corresponding to a period of seventeen years (2005-2021). DEMOSPA0521 is composed of fifteen files: a group of (monthly and daily moving averages) datasets derived from population stocks and a collection of (daily, monthly and quarterly) datasets obtained from population, death, migration and birth statistics. The intra-annual distributions were calculated by exploiting both the temporal dimensions of age and calendar. DEMOSPA0521 also includes eleven R-Code files that enables the summary datasets to be derived from the raw microdata. DEMOSPA0521 can be used to confirm established results and employed to answer new research questions.
