Spending concentration

A single county rarely dominates a state's federal-spending total, but New Castle County is the exception here, pulling in 35.1% of every dollar Delaware received statewide, a concentration usually tied to a major base, medical center, or federal facility.

Reading this number carefully

A per-capita figure this far from the norm is worth a second look before drawing conclusions. Nationally, county-level federal spending concentrates around a small number of drivers: a major military installation, a large VA medical center or federal hospital, a national laboratory, a federal prison, or a small resident population inflating an otherwise ordinary per-capita number. The dataset records dollars by place of performance only, it does not identify which of these applies to New Castle County, so this figure is best read as a prompt for further research rather than a stand-alone measure of local prosperity or federal favoritism. Readers comparing New Castle County to neighboring counties should also check population size before assuming the gap reflects total dollars rather than a small denominator.

Federal spending is attributed by place of performance, not recipient headquarters. See our methodology for the full population-source, attribution, and data-vintage rules.
