The chart below shows the UK Gini coefficient of incomes, 2007 to 2013 - Edexcel - A-Level Economics A - Question 4 - 2017 - Paper 2

One likely reason for the change in UK income inequality since 2007 is the impact of the Global Financial Crisis, which began in 2008. This crisis led to a decline in incomes for the top quintiles of earners, contributing to a reduction in overall income inequality. Additionally, government policies aimed at increasing benefits at the very bottom of the income distribution may have helped to narrow the gap, resulting in a Gini coefficient decrease from 0.36 in 2007 to 0.34 in 2010.
