Background Metropolitan Statistical Area – is a geographic area designation Developed by the Federal administration’s Bureau of the Budget (predecessor to the current Office of Management and Budget) First applied to the 1950 census as the “Metropolitan Area Program” The areas were called Standard Metropolitan Areas

The general concept of a Metropolitan Area (MA) is that of an area containing a large population nucleus and adjacent communities that have a high degree of integration with that nucleus. The purpose of MA’s is to provide a nationally consistent set of definitions for collecting, tabulating, and publishing Federal statistics for geographic areas. In Short-OMB establishes and maintains MAs solely for statistical purposes.

The Old Definitions Metropolitan Statistical Area (MSA) – area qualifies as an MSA in one of two ways: –If it contains a city with a population of at least 50,000, or –If it contains an “urbanized” area of at least 50,000 and the total metro-area population is 100,000 or more. –It was a Primary Metropolitan Statistical Areas (PMSA) Plus, the MSA may include other “central” counties – so you had: –Consolidated Metropolitan Statistical Areas (CMSA)

The New MSA OMB’s Metropolitan Area Standards Review Committee (MASRC), beginning in 1996, reviewed current definitions and, in October of 1999, recommended changes, to be effective with the release of the 2000 census. To take effect in 2002

The New MSA Starting with the New - Micropolitan Area This is a new Statistical Area containing one or more urban clusters of at least 10,000 persons but less than 50,000 persons, plus adjacent counties having a high degree of social and economic integration with the core as measured by commuting ties.

The New MSA Starting with the New - Micropolitan Area The Sacramento Economic Area includes one Micropolitan Statistical Area: > Truckee-Grass Valley, CA Micropolitan Statistical Area, which is just Nevada County. Plus federal insight, using the commuter criteria, has placed: > Gardnerville Ranchos, NV Micropolitan Statistical Area, which is just Douglas County, NV. in the new Sacramento Combined Statistical Area.

The New MSA Then.. Metropolitan Statistical Area Metropolitan Statistical Areas have at least one urbanized area of 50,000 persons or more, plus adjacent territory having a high degree of social and economic integration with the core as measured by commuting ties.

The New MSA Then.. Metropolitan Statistical Area The Sacramento Economic Area now contains three Metropolitan Statistical Areas: –Chico, CA Metropolitan Statistical Area, which is just Butte County. –Sacramento – Arden-Arcade – Roseville, CA Metropolitan Statistical Area, which includes El Dorado, Placer Sacramento and Yolo Counties. –Yuba City, CA Metropolitan Statistical Area, which includes both Sutter and Yuba Counties.

The New MSA The Micropolitan and Metropolitan categories combined account for approximately 93% of the U.S. population. –83% of the population in the Metropolitan Statistical Areas. –10% of the population in the Micropolitan Statistical Areas. Of the 3,141 counties in the U.S.: –1,090 counties will be in the 361 Metropolitan Statistical Areas –690 counties will be in the 573 Micropolitan Statistical Areas –1,361 counties remain outside of the classification.

The New MSA And then… Combined Statistical Areas, A Combined Statistical Area contains at least one Metropolitan Statistical Area and one or more of either Metropolitan or Micropolitan Statistical Areas. Combinations for adjacent areas with an employment interchange of 25% or more are automatic. Combinations with employment interchange of 15% are based on local opinion as expressed through the Congressional delegations.

The New MSA And then… Combined Statistical Areas, The Sacramento Economic Area has one Combined Statistical Area: –Sacramento – Arden-Arcade – Roseville, CA-NV Combined Statistical Area, which includes: Gardnerville Ranchos, NV Micropolitan SA. Sacramento – Arden-Arcade – Roseville Metropolitan SA. Truckee – Grass Valley, CA Micropolitan SA.
