The chart illustrates the percentage of households in the UK across four income levels-low, lower middle, upper middle, and 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%. In contrast, the high-income group represented the smallest share, although it experienced the most noticeable growth over the decade.
In 2009, low-income households made up approximately 21%, and this figure rose slightly to about 22% in 2019. A similiar upward was seen in the lower-middle income group, which increased steadily from roughly 27% to 29% during the same period.
The upper-middle income category remained the largest group, rising modestly from around 32% in 2009 to approximately 34% in 2019. Meanwhile, the proportion of high-income households showed the fastest increase, growing from about 14% to nearly 19% over the ten-year period.
