An issue of interest in the literature that explores the drivers of inequality is the distributional bearing of tax and transfer policy, where an important theme concerns changes in the relative treatment of alternative population subgroups.  We develop an empirical approach for quantifying the value judgements implicit in the relative treatment of demographic subgroups by a tax and transfer system.  We apply this approach to UK data reported at annual intervals between 1968 and 2015, documenting remarkable improvements in tax and transfer treatment enjoyed by some population subgroups – particularly families with children and age pensioners – relative to the wider population.  We show that accounting for the changing value judgements implicit in tax and transfer policy provides a fresh perspective on the evolution of income inequality and redistribution; one that departs from the prevailing view that UK inequality stopped rising from the early 1990s.
