It does. It breaks down overall expenditure on transport, energy, food and other goods and services. It shows how one can create tailored inflation rates for younger or older, lower income or higher income, rural or urban, those with cars or those without cars, and homeowners or renters. We provide tailored inflation rates to show that while 5.7% is the average inflation rate, some groups face a higher rate and some groups face a lower rate. We estimate all of those.
