Tajikistan was one of the fastest growing countries in the Europe and Central Asia region during the last decade. The economic growth was widely shared by the population and as a result poverty (measured by the national poverty line) declined from 73 percent in 2003 to 47 percent in 2009 accompanied by falling inequality. Consumption growth of the bottom 40 percent of the population-a measure of shared prosperity proposed by the World Bank- was positive, pointing out that the growth was shared among the less well off. This work presents a diagnostic of shared prosperity and poverty reduction in Tajikistan during 2003-2009. The paper also focuses on quantifying the main drivers of poverty reduction, shared prosperity, and intra-generational mobility (class transitions). Some of the mechanisms of poverty reduction are explored in detail. Finally, main impediments to inter-generational mobility are discussed.
