Identifying trends in living standards in Tanzania has been a subject of considerable interest. Analysis of a household budget survey conducted in 2007 revealed consumption poverty rates approximately similar to the rates calculated from a comparable survey conducted in 2001. This stagnation in consumption poverty occurred despite relatively high published rates of economic growth over the same period and little change in measured inequality. Price inflation over the same period as measured by the household budget survey also differed drastically from inflation rates derived from the published consumer price index (CPI) and the GDP deflator. The growth–poverty–inequality conundrum alongside the wide divergences in measured inflation provoked a great deal of analysis. More recently in 2015, the World Bank published a poverty assessment based on a household budget survey conducted in 2011/12 and found a reduction in consumption poverty of about six percentage points.
