Inventory fluctuates constantly, so we calculate the monthly measure as the inventory at the start of each day average across the entire month. Expected values were refit in August 2026 and now align to the month they describe. Geography notes: Metropolitan Statistical Areas are defined by the U.S. Census Bureau after each decennial census.
