censuses. The minimum level of requirement , which is the legal obligation
established by the EU Regulation, is amply met for all the variables referred to
population.
According to the Housing Census, developments are currently not so
advanced. Anyway although it is proven that the EU regulation would also be
complied with the strategy adopted, more efforts and time are needed to
analyze the final quality of the product. In the least favorable scenario, the
Housing Census would require a reduced and selective fieldwork operation in
certain enumeration areas (those with poorest quality of information) of the
national territory.
On the other hand, it is proposed to complete the Census project with a
sociodemographic survey parallel to the census. The size of this survey could
reach 1% of the total population and would allow to provide information
useful for imputation of those variables that are not sufficiently well-covered
by the Population and Housing Census. In addition, information of this survey
has been largely demanded among users.
As a conclusion, 2021 Spanish Census can be considered “on the right
track” and the main methodological doubts are cleared, but is not built yet.
During the following years, an intense work of refinement in all the variables,
especially in the Housing part, is required.

2. The Population Register (Padrón)
The main source as regards both population stocks and migration statistics
in Spain is the population register, named Padrón in Spanish. Padrón is the
official list of residents in each one of the 8,124 municipalities in Spain (as of
1st January 2018).
In Spain there are as many registers as municipalities. But there is a law, in
force since 1996, integrating all these municipal lists into a single national
database. There are also legal procedures to keep this database and the
municipal files interconnected and updated on a monthly basis. This is made
through the statistical office of Spain, INE. So, unlike other countries where the
police or other administrative bodies are in charge of population registers, in
the case of Spain, INE is the national institution that coordinates this single
national population register.
Each month INE receives all the changes produced in every municipality.
With this information INE performs validations and forwards these results to
all the municipalities, to avoid duplications and also to include deaths, births
or acquisition of Spanish citizenship that INE receives on a monthly basis from
the Civil Register. Furthermore, all the consular offices of Spain throughout the
world (around 250) are also connected to Padrón like the municipalities.
