Survey under-coverage of top incomes leads to bias in survey-based estimates of overall income inequality. Using income tax record data in combination with survey data is a potential approach to address the problem; we consider here the UK's pioneering "SPI adjustment" method that implements...

This report examines how household incomes were changing in the UK up to the eve of the COVID-19 pandemic, and how other measures of household living standards have changed over the course of the pandemic. In particular, we use the latest official data covering years up to 2019-20 to provide a...

Estimates of UK income inequality trends differ substantially according to whether estimates are based on household survey data (used for official statistics) or tax return data (used in the top incomes literature). We reconcile differences in variable definitions and combine survey and tax...

The focus of this report is the distribution of household income in the UK. We assess the changes to average incomes, income inequality and poverty that occurred in the latest year of data (2014-15), and put these in historical context using comparable data spanning the last 50 years. The...

How have household incomes evolved since the onset of the financial crisis? How has the gap between rich and poor changed? How have living standards changed over time for different parts of the population? How many people are in poverty and which groups are most likely to face poverty? Each...

We study earnings and income inequality in Britain over the 25 years prior to the COVID-19 pandemic. We focus on the middle 90% of the income distribution, within which the gap between top and bottom in 2019-20 was essentially the same as a quarter-century earlier. We show that this apparent...
