possible to validate the quality of the information recorded by the interviewer.
It also has a Cartographic Module, whose purpose is to record the
cartographic updates at the block, town and road levels, allowing to digitize
the polygons of new areas, cancel those that are no longer in the field and
graphically represent changes such as fusions and divisions of areas, allowing
immediate updating of the cartography.
On the other hand, the Module for the Coverage Verification will be
implemented for the Census 2020, with the objective of facilitating the
activities of the staff and, if necessary, to collect the information of the missing
population in order to improve coverage in the enumeration of dwellings and
people.
The Census Administrator will integrate the necessary computer tools for
the execution of the Post-Enumeration Survey and a Module for the
comparison between the data obtained by the enumeration and the post-
enumeration.
This census also aims to promote self-enumeration, either via the internet
or by telephone, so an application is available to the population in which the
short form can be completed. It should be mentioned that this system will be
adapted to collect the information on collective living quarters and on the staff
of the Mexican Foreign Service.
The OPERA system, on the other hand, includes the module to monitor the
integration of data collected in the field, allowing the generation, analysis and
monitoring of certain indicators of coverage, speed and productivity in the
census, important information for management decision making during the
enumeration operation.
The data processing strategies include the corresponding design of the
coding, validation and results generation systems with their corresponding
quality controls.
In order to carry out the data processing, the Processing Monitoring and
Control System will be used to monitor each of the stages. The automatic
coding, by means of algorithms that recognize the textual information of the
questionnaires, assigns a code of the predefined catalogues and later assigns
the workloads for the computer-assisted coding. Once the coding has been
completed, the automatic validation of the records is carried out. This system
also includes testers of the validation criteria in order to ensure the correct
application of the pre-defined algorithms. During each stage the application
provides progress reports in real time. Additionally, reports on the quality of
the information are generated, and a log of the changes made to the data is
created. In parallel, the assignment of the geographical codes of the National
Geostatistical Framework is followed up. Finally, this stage makes available the
database for the activity of Figures Release, which consists of a statistical
review of the historical changes of sociodemographic indicators at the state,
