In "Poor Numbers," Morten Jerven embarks on a groundbreaking exploration into the murky depths of African economic statistics, revealing a world where numbers do not always tell the truth. With a keen analytical eye, Jerven uncovers the complex reality behind the creation and use of economic development statistics across sub-Saharan Africa, presenting a compelling argument on the severe implications of unreliable data. This meticulously researched book illuminates the daunting challenges faced in improving statistical capacity, a critical yet often overlooked cornerstone for effective development policy and international aid allocation. Jerven's investigation is not just academic; it is a call to action for policymakers, scholars, and international stakeholders, urging a reevaluation of the dependence on figures that may mislead as much as they inform. "Poor Numbers" masterfully demonstrates how inaccurate statistics can lead to misguided policies that fail to address, and sometimes exacerbate, the real issues at hand. Morten Jerven's analysis goes beyond the surface, questioning the very foundation upon which financial aid and development initiatives stand. The book serves as a vital critique of the current "evidence-based policy" approach, challenging the global community to reconsider how development success is measured and, ultimately, achieved. By shedding light on the disarray within sub-Saharan Africa's statistical systems, Jerven not only highlights the misallocation of scarce resources but also ignites a crucial conversation about the path forward. This is a pivotal read for anyone invested in the future of African development and the accurate portrayal of its economic landscape.
