The chart illustrates the percentage of households with different income levels in the UK across four levels, ranging from low to high, in 2009 and 2019.
Overall, the upper-middle income group accounted for the largest proportion of households in both years, at around 32-34%. By contrast, the high-income group represented the smallest share, although it experienced the most noticeable increase over the decade.
In 2009, households in the low-income category made up approximately 21%, and this figure rose slightly to about 22% in 2019. A similar upward trend can be seen in the lower-middle income group, which increased steadily from roughly 27% to 29% over the same period.
The upper-middle income level recorded the highest proportions overall, rising modestly from around 32% in 2009 to approximately 34% in 2019. Meanwhile, the high-income group showed the fastest growth, increasing from about 14% to nearly 19% during the decade.
In summary, all income groups in the UK experienced growth between 2009 and 2019, with the most significant rise occurring among high-income households.
