He reshaped how the world measures poverty, establishing the dollar-a-day standard that defined global development goals for decades.
Born in Australia, Martin Ravallion’s intellectual journey took him from the London School of Economics to the heart of global policy at the World Bank. His work was never confined to abstract theory; it was a relentless pursuit of a single, practical question: how do we accurately count and understand the world’s poor? This focus led him to pioneer the methodology behind the famous international poverty line, a tool that transformed vague sympathies into concrete targets for governments and aid organizations. Later, as a professor at Georgetown, he continued to scrutinize the mechanics of inequality and social protection, arguing with quiet persistence that data must serve humanity. His legacy is a framework that, for better or worse, has dictated where billions of dollars in development spending flow.

Martin was born in 1952, placing them squarely in the Baby Boomers. The events that shaped this generation — postwar prosperity, civil rights, Vietnam, and the counterculture — shaped the world they entered and the choices available to them.

His PhD thesis at LSE was on the economics of housing markets, not poverty directly.
He was a vocal critic of how the poverty line could be misused, emphasizing it was a tool, not a perfect truth.
Ravallion contributed to the 'PovcalNet' software, an online tool that allows anyone to compute global poverty measures.
“The way we measure poverty can affect what we do about it.”
