This database includes several tables highlighting the hierarchical nature of the geographic coding systems used by the U.S. Office of Management and Budget for metropolitan areas, with reference to a series of other geographic tables maintained by the Census Bureau and a cross-reference table.
Under the OMB Metro Areas pulldown menu:
Consolidated Statistical Areas lists all the CSAs as of OMB's 2017 definitions
Core Based Statistical Areas lists all CBSA metropolitan and micropolitan areas as of OMB's 2018 definition and the CSAs, if any, in which they are embedded
Consolidated New England City and Town Areas lists all CNECTAs and NECTAs as defined by OMB most recently in 2013 (no updates in 2015, 2017, 2018, 2020) and delineations of NECTA Divisions by Census as of 2020
New England City and Town Areas lists all NECTA metropolitan and micropolitan areas as defined by OMB most recently in 2020 and the CNECTAs, if any, in which they are embedded
Under the Census Geographies pulldown:
Region lists the highest-level Census regions
Divisions lists Census divisions and the regions in which they are embedded
State lists the codes for each state and territory
Metro Divisions lists the divisions into which certain CBSAs are divided
New England City and Town Divisions lists the divisions into which CNECTAs are divided
County lists all counties and county-equivalents, the CSA and CBSA in which they are embedded, if any, their status as central or outlying in those regions, and a Google maps link. Current as of 2015 Gazeteer updated through 2018.
County Subdivision lists all county subdivisions, the counties within which they are embedded, and their "functional status" code as assigned by the Census. Current as of 2015 Gazeteer updated through 2018. Metro/non-metro and economic dependency classifications per ERS are current as of 2015.
Place lists all Census places, their counties, their types, the metro areas within which they are embedded if any, whether they are a principal city within those metro areas, and a Google maps link. Updated as of 2021. UPDATE (12/19): Deleted all Minor Civil Divisions from New England and selected other states which may be incorporated places and/or recognized commonly as places but not considered Census places.
Urban Area lists all Urban Areas and Urban Clusters as defined by the Census. Current as of 2015
Census Tract lists all by county and state. Current as of 2015 updated through 2016.
Under the Cross Reference pulldown:
Urban areas cross-referenced by Place.
Here are the principal views for this database:
Each table in the left-hand column opens in summary view:
By default the table sorts by the first column but you can click on any column title to change the sort order.
The summary view shows only a few rows at a time, but use the pager tool to gain access to the rest.
This is also the view you will see after conducting a search.
Clicking the paper icon on the leftmost column of the summary table opens a detail view for the record clicked.
The "previous/next" links will take you through any summary table, whether the full dataset or the result of a search.
In some cases, the detail view may reveal a field not included in the summary view. For example, the detail view for State lists quite a number of attributes for each state that are not in the summary table.
For tables listing specific geographic areas, the detail view also includes a list of those codes at one level of greater specificity that belong to this code. For example the detail view for a CBSA indicates which counties are in that CBSA, and the detail view for a County indicates which places are in that County.
For the metro area and county tables, the detail view also shows which colleges and universities can be found in that area.
You can conduct a "quick search" by one or two fields from the summary view. However, you can also click the search button to open a full-featured search:
You can enter one or more fields. Don't overdetermine a search.
By default, the search is conducted as a Boolean AND of terms in any field but you can change this to Boolean OR in the dropdown.
Fields with "equals," "starts with," or "contains" require a text entry. You may use Boolean AND or OR within these fields.
Be sure to "clear" the search to get back to the full summary listing.
