The distribution of income, consumption and wealth continues to be a central area of IFS research. Amongst the many aspects of our work in this area, we seek to chart, explain, and understand changes in inequality in wages, earnings, incomes and consumption, in the UK and other countries; we also seek to examine the effectiveness of a wide range of policies aimed at reducing poverty - including taxes and benefits, and other types of policy interventions - both at home and abroad.
Our research is also concerned with the welfare implications of changes both to inequality and poverty. These depend on how far they are caused by permanent changes in the relative standings of individuals in the income distribution (e.g. a change in the return to certain skills caused by technical progress) or by changes in the frequency of short-lived events (e.g. temporary layoffs), as well as the availability to individuals of specific insurance and other mechanisms to mitigate unexpected events.
For useful facts and figures, visit our Incomes in the UK section, where you will also find out interactive model, Where do you fit in?, which uses the latest data to plot your position in the income distribution.

The first half of the report sheds some new light on the following questions with a detailed and consistent comparison of income distributions in Western Germany and the UK from 1984 to 1992. To what extent was the income distribution in Western Germany similar to the UK in 1984? Did the inequality of West German incomes rise to the same extent? What was the differing role of the labour market, the tax and benefit system and demographic change in each country? The second half of the report concentrates on whether and how education, training and wage setting systems together with other institutional factors in Western Germany can explain the differences relative to the more deregulated UK labour market.
