How these figures are made. BRB lists every county an issuer serves and gives no shares, so an issuer's debt counts in its home county, the first county listed for it, and each dollar counts once statewide. Of Collin County's $24,418,778,124, $97,540,000 is owed by 3 issuers that list other counties too; 3 issuers that list Collin County count in another. Debt per resident divides principal outstanding by the population on Collin County government's own row (1,254,658 residents) for the same fiscal year; per resident in the issuer list uses each government's own reported population. "Not reported" is never shown as zero.
