How these figures are made

Total principal outstanding

Principal outstanding at the fiscal year end, summed over the local governments attributed to the county; computed here from BRB's tables for fiscal year 2025. It has no denominator.

Which governments count here

BRB's County field lists every county an issuer serves and gives no shares. An issuer's debt counts in its home county, the first county listed for it, so each dollar counts once statewide. Of Collin County's $24,418,778,124, $97,540,000 is owed by issuers that list other counties too. Issuers that list Collin County but count in another are under "Also serve Collin County". Per resident in the issuer list uses each government's own reported population, where it reports one.

Not reported means no government of the chosen type in the county reported the amount that year, or the denominator was not reported. It is never shown as zero.

Fiscal years: Texas fiscal years run September 1 to August 31. Local governments report at the end of their own fiscal year, as BRB's tables do.
