Measuring Development 2020

  • Squares in different sizes and colours

Participants learned how new sources of “big” data–including call detail records, satellites, and remote sensing networks–are changing the landscape of global development, while offering timely research opportunities during the COVID-19 crisis. These data sources are particularly valuable to researchers and decision-makers as they provide data at a much higher frequency and lower marginal cost than traditional surveys. While big data and survey data can each be useful on their own, hybrid approaches that enrich big data with survey data enable exciting new analytical opportunities.

In an environment where traditional forms of field-based data collection will be constrained for the foreseeable future, it is particularly important to highlight non-traditional methods for collecting and analyzing data related to international development.
