Abstract: Spain plans to carry out its first register-based census in the next 2021 round, becoming one of the biggest countries in the world using this approach. Since 1996, when the Population Register was created, census methodologies have evolved enormously and Spain has vastly increased the use of administrative registers in official statistics. In the last 2011 census, it was too soon to completely rely on administrative data, so a combined census was performed. Now, in 2018, 22 years after the creation of this register, INE faces this challenge with confidence. The availability of a variety of administrative registers and the fact that INE has access guaranteed by law to them, endorses this step forward. There are still some difficulties to overcome and a great effort is being made today, collecting any suitable administrative source, processing and integrating data, developing new IT tools, and of course, evaluating the quality of the whole statistical product. A complete population census test referenced to 2016 proved very satisfactory which enables for Spain planning to conduct a register-based census in 2021.
