Created 2012-09-18 by Jean Roth , jroth@nber.org , 2012-09-19 In the 2003-08-19 Source crosswalk file, Angoon, Alaska with SSA county code 02030 has a fips county code of 02031. This FIPS county code does not seem to exist elsewhere, and it appears that the fips county value should be 02231, so this change has been made to the SAS and Stata files. -------------------------------------------------------------------------------------------------------------- name: log: /disk/data2/ssa-fips-state-county-crosswalk/angoon.txt log type: text opened on: 8 Nov 2012, 13:58:38 . list county-msa_1 if regexm(county,"ANGOON") +---------------------------------------------------------------+ | county abbr q_ind ssa fips msa_1 | |---------------------------------------------------------------| 72. | ANGOON AK 02030 02031 | 99. | SKAGWAY-YAKUTAT-ANGOON AK 02231 02231 | 100. | SKAGWAY-HOONAH-ANGOON AK 02232 02232 | +---------------------------------------------------------------+ . log close name: log: /disk/data2/ssa-fips-state-county-crosswalk/angoon.txt log type: text closed on: 8 Nov 2012, 13:59:13 -------------------------------------------------------------------------------------------------------------- msbea.zip source file: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/Acute-Inpatie nt-Files-for-Download-Items/CMS022639.html
