Data the X ray of development

In this episode of Data Talks, Wolfgang Fengler sits down with former IFC CEO and World Bank leader Philippe Le Houérou for a deeply personal and wide-ranging conversation on data, development, ideology, and global change. From witnessing revolution and violence as a teenager in Ethiopia to reshaping the IFC through evidence-based strategy and measurable development impact, Philippe reflects on the experiences that shaped his belief that “numbers are the X-ray to many problems.” Together, they explore why data matters, how evidence cuts through ideology, and why better diagnosis leads to better decisions in economics, policy, and development. The conversation also dives into the transformation of the IFC under the “IFC 3.0” strategy, the rise of private sector-led development, the evolution of global poverty reduction, and the growing importance of data systems in emerging economies. Philippe shares candid insights into leadership, institutional reform, and why development finance must evolve for a changing world. The episode closes with an unexpected reflection on Philippe’s favourite number: zero. Describing it as one of humanity’s greatest intellectual breakthroughs, he explores the “genius of zero” — where mathematics, philosophy, and human progress meet.In this episode of Data Talks, Wolfgang Fengler sits down with former IFC CEO and World Bank leader Philippe Le Houérou for a deeply personal and wide-ranging conversation on data, development, ideology, and global change.
