While governments around the world have made conscious efforts to promote social inclusion, and major progress in fulfilling basic needs has been witnessed during the last decades, certain groups of people...

We revisit trends in within-country income inequality using a newly integrated dataset that covers at least 70 per cent of the global population since 1980. We investigate absolute and relative inequality trends across the past four decades, combining the use of Lorenz curves with a set of...

– Reflections on my first six months as Director

Income inequality is the result of complex processes with multiple interacting driving forces but understanding those drivers in emerging economies is particularly difficult because of data and analytical challenges. While most middle-income countries produce comprehensive household surveys these...
The many faces of inequality Measuring inequality isn’t as simple as it may seem. We know that since the 1970s global inequality has been falling in relative terms, but absolute inequality has been increasing over the same period.

Much of this work focuses on horizontal inequality as an independent causal variable, rather than an outcome of various...
