Higher or lower is not itself good or bad — it describes the neighborhood, not the investment.
ZIP-level figures come from ZIP Code Tabulation Areas, which approximate but do not exactly match USPS ZIP codes. A missing value is suppressed or unavailable at this sample size, not zero. Estimates for 2019–2020 use the 2010 ZCTA boundaries and 2021–2024 the 2020 ones, so a step between those two years may be a boundary change rather than real movement.
