The presentation will address the production and use of data generated in large statistical operations, such as decennial censuses or household surveys in countries, cities and territories with situations of violence, threat or exclusion. The contents include security reporting solutions to alert census trusts about potential problems in census tracts. Also, the speaker will illustrate the potential of massive data contributions in the form of crowdsourcing that open platforms can mean for collecting information in countries such as El Salvador, and how data co-production can contribute as an added value when using information collected by civil society. Finally, the talk will present aerial survey tools such as the Data Cube to address the raised issue with open data satellite coverage.
