Context
The Democratic Republic of the Congo (DRC) faces significant humanitarian and development pressures, where timely, accurate population and mobility data can be critical for effective response.
Mobile phone metadata (call detail records, CDR data) offer a powerful means of generating these insights, but realising its potential depends on regulators having the technical knowledge and confidence to authorise and oversee its use.
We have been supporting decision-making in the DRC since 2018, working with the ARPTC, the country's telecommunications regulatory authority, as a key institutional partner.
As part of this engagement, we’ve worked with the ARPTC to deepen their understanding of how we process and analyse CDR data to produce mobility estimates for humanitarian and development purposes, and how we manage privacy and data protection considerations throughout.
Increasing the ARPTC's understanding of CDR data analytics for good
In February 2026, supported by the King Baudouin Foundation, we delivered a three-day intensive workshop with eight members of the ARPTC's technical staff in Kinshasa. Sessions covered :
- An introduction to the processing and analysis of CDR data
- Techniques for protecting privacy and enhancing confidentiality
- Potential applications of mobility and population estimates across various sectors (health, displacement, humanitarian planning, etc.)
- Interactive sessions and discussions on the institutional and regulatory frameworks required to support the wider sharing of data and analytical outputs.
The impact: A very well received workshop, with participants rating its overall usefulness at 3.8 out of 4.
All six respondents who completed the evaluation gave the maximum score for both understanding ethical and governance considerations, and their likelihood to recommend using mobility estimates.
Participants came away with greater clarity on CDR analysis methodologies, stronger confidence in interpreting and communicating population estimates, and a clearer view of the data's potential. They also identified promising new applications, including infrastructure planning, urban planning and telecoms network optimisation.
Flowminder’s workshop on statistics derived from mobile phone metadata has been beneficial for the DRC and, in particular, for the ARPTC. Indeed, it has enabled us to understand how this data can be processed to produce statistics such as those on population movements. Thus, the collaboration between the ARPTC and Flowminder in this area is beneficial to both parties as it supports data-driven decision-making.

This capacity-building workshop forms part of our ongoing collaboration with the ARPTC. Our data contributes to the Congolese government’s development objectives, and this workshop was therefore designed to strengthen the ARPTC’s capacity in data production methodologies, with a view to enabling the sustainable and strategic use of data to support public policy in the DRC. This training represents a significant step forward.

Next steps
We will maintain ongoing dialogue with the trained ARPTC team to consolidate progress, while initiating conversations with ARPTC leadership to explore finer temporal granularity in analyses, with weekly or daily internal mobility estimates which are particularly critical in the context of humanitarian crises and natural hazards.
This work forms part of our broader solutions on digital transformation, novel datasets, and the responsible use of AI and data science for public good. We work with governments, regulators, and humanitarian actors to unlock the potential of emerging data sources while ensuring robust privacy and governance standards.
