Activity 01
Build-Your-Own CPI
Small groups receive a 'family profile' with income, household size, and typical monthly spending patterns. Groups assign percentage weights to major categories such as food, housing, transportation, and healthcare, then apply price changes from actual BLS data to calculate their family's personal inflation rate. Groups compare rates and discuss why different households experience inflation very differently.
Explain how the Consumer Price Index (CPI) is constructed and its limitations.
Facilitation TipDuring Build-Your-Own CPI, circulate and ask each group to explain why they assigned different weights to their basket items.
What to look forProvide students with a simplified CPI data table for two consecutive years. Ask them to calculate the annual inflation rate and write one sentence explaining if purchasing power increased or decreased for consumers.
