The 'real' inflation rate for young adults is 2-3x the official CPI because CPI underweights rent, childcare, and education

The official CPI says inflation has been 3-4% annually since 2020. But CPI weights housing at 36% using 'owners equivalent rent' — a theoretical measure of what homeowners would pay to rent their own house — not actual rent increases. If you are a renter (which 65% of under-35s are), your housing costs rose 30%+ since 2020, not the 20% CPI implies. CPI weights education at 5.8% — but if you are paying student loans, education is 15-20% of your spending. CPI weights childcare at 1.5% — but if you have kids, childcare is 15-25% of your spending. The 'official' inflation rate describes the spending patterns of a median 50-year-old homeowner, not a 28-year-old renter with student loans. So what? Policymakers, employers, and central banks use CPI to set monetary policy, adjust wages, and determine benefits. When CPI says inflation is 3%, employers give 3% raises. But if your actual inflation is 7% (because you are a renter paying for childcare and student loans), your real wages decline 4% per year. Over 5 years, your purchasing power drops 20% while the government claims inflation is 'under control.' Young adults feel increasingly squeezed despite 'low' official inflation because the official measure does not reflect their spending. Why does this persist? CPI is calculated by the BLS using a fixed basket of goods weighted by average consumer spending. By definition, it represents the average consumer, not any specific demographic. Alternative measures exist (CPI-E for elderly, chained CPI, PCE) but no 'CPI-Y' for young adults. Creating age-specific inflation indices is methodologically straightforward but politically inconvenient — it would reveal that inflation policy benefits older, wealthier consumers at the expense of younger, poorer ones.
