The Office for National Statistics has produced experimental household cost indices that can be used to compare the inflation experienced by high- and low-income households. This chart shows that there have been four phases of inflation since 2010:

  • The first period from the start of 2010 to around August 2011 was a period of rising inflation, with low-income households seeing a bigger rise than high-income households.
  • The second period from August 2011 to mid-2015 was a period of falling inflation, but during the whole of this period inflation was higher for low-income households than high-income ones.
  • The third period from mid-2015 to late 2017 was of rising inflation, with high-income households seeing slightly higher inflation.
  • The final phase in this data is from late 2017 to the end of 2019 and shows falling inflation. Again high-income households are seeing slightly higher inflation.
