We treat the $5,000 national baseline as a family-of-four budget, scale each category by Washington's index (housing moves 1.5x as much as the index, groceries 0.8x, and so on), then apply assumed single-adult shares per category (housing 65%, groceries 30%, transportation 55%, healthcare 30%, utilities 60%, other 45%).
