$100K does not buy the same regional basket

BEA's 2024 regional price parities turn the same nominal salary into a price-level-adjusted comparison for California and Arkansas.

INPUT AND EVIDENCE LEDGER

Put the two cases on the same footing.

DECISION READING

Read the gap, not just the winner.

The RPP layer makes a broad regional difference visible, but it cannot replace the household's actual rent, childcare, insurance, commute, and consumption pattern. MOVE should use it as context, then let entered costs drive the decision.

SOURCE SNAPSHOT

Official context and the limited role it supports.

SENSITIVITY

Conditions that can reverse the gap.

  • Housing rents are a major RPP driver and can differ sharply within each state.
  • The latest release describes 2024, not a live 2026 household budget.
  • A household basket can diverge from the all-items regional basket.
