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 Harris County's $19,877,621,739, $573,205,572 is owed by 1 issuer that lists other counties too; 0 issuers that list Harris County count in another. Total principal outstanding: principal outstanding at the fiscal year end, summed over the local governments attributed to the county. "Not reported" is never shown as zero.
