2010 census round is producing digitalized information in quantity and quality. Geo census data, census information crossed with geographical information has merited special attention from all Governments in the region, particularly explained by the wide availability of advanced information and communication technologies to cover the stage of the collection of data.
In addition to its important contribution in the census, geoinformation can also play an important role in facilitating the immense challenge of the dissemination of census data, not only because of its great accuracy but also because of its unique characteristic of being able to present information through images that help to abstract and summarize large volumes of data. Based on information that Geocensos had access to by interviewing a large number of countries in Latin America and the Caribbean Census the following was revealed:

The available GIS systems in the surveyed COs (census offices) promise a great potential according to the degree of detail in the geographical coverage available, most of which have it at the level of blocks. In particular, given the wide availability of the ESRI technology in the COs, an immediate capacity of interoperability in the use of census data in the majority of countries is possible. The need to disseminate census data using geographical information as a vehicle has been highlighted in several regional bodies. The “Handbook of geospatial infrastructure in support of census activities” prepared by UNDESA in 2009 devotes an entire section to promote the use of infrastructure geospatial countries for the dissemination of census results.
On the other hand, the Regional Workshop "Census cartography in Latin America for the 2010 census round" venued by ECLAC in December 2008 stressed the need to "work and plan (geographical) products beyond the activity of the census, with the aim of giving greater added value to census cartography". Recently, in July 2012, the CEA ECLAC Commission of censuses under the leadership of (the Bolivarian Republic of) Venezuela has enhanced the importance of the use of the cartography for the dissemination of censuses. In addition to training seminars for operators of census information the Commission has placed special emphasis on dissemination and spatial analysis of census information.
All these proposals and initiatives require all COs in the region to solve strategic and technical aspects on all issues relating to geographical tasks after the census geographic inventory, including the dissemination of geographic data. After investing enormous resources for geographic data, it is needed to oil editing and updating processes in the geographical database permanently for an effective exploitation and efficient usein future projects produced by the census offices. For example, to deliver data at a disaggregated level it is necessary to settle issues related to the publication and the preservation of the private nature of some data. Another issue concerning the publication of data is if to provide or not such data free of charge, or seeking income selling value-added products, such as CD-ROM or DVDs with data. The same must be resolved if an amended census area level data should be delivered or geographical information can be shown in new units for publication such as conglomerates.
Once solved the above issues plus others related to on field census unique opportunities to exploit several products and services of a geographical nature may arise, both static and dynamic. Among others, map viewers, spatial files with attributes for use in commercial software of GIS and cartographic products tailored to offer through the Internet. Many public bodies may also benefit from thematic maps, atlas, spatial statistical analysis, geo database and interactive web sites, expanding the traditional offering of census statistical data.
