The Missoula, Montana MSA (FIPS Code 5140) was defined effective June 30, 1998. The Missoula, Montana MSA comprises Missoula County, Montana. The MSA's central city is Missoula, Montana.

OMB Bulletin No. 98-06 with the list of all MAs as of June 30, 1998, is available from the National Technical Information Service (NTIS), Document Sales, 5285 Port Royal Road, Springfield, VA 22161, telephone 1-800-553-NTIS (Accession Number PB98-146160). This list is also available through NTIS in electronic form (Accession Number PB98-502198). OMB Bulletin No. 98-06 and the current list of MAs are available electronically from the OMB home page; go to OMB Documents/Selected OMB Bulletins.
