To turn Call Detail Records (CDR data) into usable insights for humanitarian and development purposes, several stages of processing, R&D and analysis are required.
In this section, you will learn about the process for turning data into insights, the core methods required for analysis, as well as how to calculate the most fundamental CDR data aggregates and mobility indicators for decision-making in low- and middle-income countries.
Key information to produce mobility indicators from CDRs
From data to insights
Learn about the process to generate insights from CDR data once secured access to pseudonymised data is granted
The production of mobility aggregates, and therefore indicators, from CDR data is underpinned by methodologies for analysing CDR data. Discover them here
Calculating mobility aggregates
A mobility aggregate groups the pseudonymised CDR data of many individual subscribers into an output that characterises the behaviour of the entire group of subscribers - learn the key aggregates and methods to calculate them
Calculating mobility indicators
We can produce a broad range of different types of indicators from CDR aggregates. In this section, we describe how to calculate indicators from four common classes.
