“Metropolitan” is the new delineation for the Twin Falls area comprised of Twin Falls and Jerome counties, announced in the Federal Register by the Office of Management and Budget (OMB) dated August 2017. Before that, this geographic area or ‘delineation’ was designated the Twin Falls Micropolitan Statistical Area (MicSA).
In practical terms, what does this change mean?
The most important clue is found in the second word — Metropolitan Statistical Area (MSA). The purpose of the delineation is strictly for statistical activities, although a number of agencies both inside and outside the federal government make use of the delineation for nonstatistical program applications.
