municipal and by locality size. For this activity, the Libera System will be used,
which allows the control of the revision of each indicator, but also serves as a
repository for the documentation that supports changes found in some
statistics.
Data processing for the publication of results is done mainly by predefined
algorithms programmed ad-hoc in statistical analysis software, and in the case
of products that require editing for presentation, automated processes are
generated to facilitate the task, considering the editorial provisions of INEGI.
There are also three web systems that allow more experienced users to access
information in greater detail, these are: Consultation of Census Information
System, which allows to associate census statistical information with the
geographical space to which it belongs, to facilitate the interpretation of
sociodemographic phenomena, through the generation of thematic maps; the
Territorial Integration and Locality Consultation System, which facilitates the
query of historical information of each inhabited locality of the country; and
the Sociodemographic Panorama of Mexico, which is a dynamic consultation
system that integrates, as a synthesis, relevant data to know the basic
demographic, social and economic characteristics of the population and
housing in Mexico. In addition, a series of files with the microdata of the census
sample are available in different formats to facilitate its use.

4. Field tests
In the framework of the planning stage of the Census 2020, two field tests
were executed in order to determine, in the operational field, the optimal
characteristics of the mobile devices, the required computer tools and to
define the operative procedures according to this new paradigm.
In order to test the operation of mobile devices and computer tools in
different climates and areas (urban / rural) the test of operational strategy and
computer equipment was conducted. During six weeks, Enumeration
operations were executed, Verification and Self-enumeration, and the flow of
information between each of these schemes was tested. For this test, a public
bidding was carried out in which six devices of five different models were
purchased, in such a way that the computer tools could be tested on
equipment with various technical characteristics, all with Wi-Fi Technology,
Micro USB, GPS, as well as voice and data (SIM); and computer tools for both
Windows and Android were developed in order to determine the most
suitable operating system for its operation.
Concerning the systems for the preparation of operational planning,
recruitment and selection of staff, training, logistical and operational
monitoring, integration of information to the central database, among others,
the data of the observation strategy indicate quite acceptable results,
providing elements that allowed to optimize its performance. Regarding the
