school districts; expenditure limitation

HB 2507 updates how Arizona calculates annual spending limits for local governments like cities, towns, and counties. It revises the formula to adjust these limits each year based on population growth (using July 1 estimates) and inflation (via GDP price deflator changes), replacing the previous method. The bill requires the state commission to calculate and report these adjusted limits to local governing boards by specific deadlines each year. This directly affects all political subdivisions subject to Arizona's constitutional expenditure limits, ensuring their spending caps reflect current population and economic conditions. The change focuses on procedural accuracy in limit calculations, not new spending policies.
