In many high-income countries, governments seek to ensure that households at least have sufficient incomes to afford basic essentials such as food and clothing, but also to help citizens reach socially acceptable living standards allowing full participation in society. Their success in doing so is commonly monitored in terms of how many citizens are below a poverty line set relative to median income, and by how far below it they fall (the ‘poverty gap’). Yet the threshold below which this gap starts to be measured is arbitrary, begging the question of what level of low income needs addressing. A more ambitious measure, presented in this paper, considers the extent to which people fall short of a benchmark representing a socially agreed minimum standard. This ‘low income gap’ can be used to represent the distance a society has to go to eliminate income that is undesirably low. The paper presents the indicator, its meaning and some recent trends in the United Kingdom, where the methodology behind the indicator has been pioneered. The results demonstrate that this empirically derived benchmark has the potential to be of value in other countries, in assessing whether they are making progress in reducing low income.
