Frequently Asked Questions

What are the Census regions and divisions?
The United States is broken down into four regions, which are further divided into 9 divisions. Regions, divisions, and the States they comprise (including the District of Columbia) are as follows:
REGION DIVISION STATES
Northeast New England Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, Vermont
Middle Atlantic New Jersey, New York, Pennsylvania
South South Atlantic Delaware, District of Columbia, Florida, Georgia, Maryland, North Carolina, South Carolina, Virginia, West Virginia

West North Central Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, South Dakota
West Mountain Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, Wyoming
Pacific Alaska, California, Hawaii, Oregon, Washington
How are the labor force estimates for census regions and divisions calculated?
Under real-time benchmarking, a tiered approach to estimation is used. Model-based estimates (using a univariate form) are developed for the nine Census divisions that geographically exhaust the nation. These estimates are controlled to the national levels of employment and unemployment. State model-based estimates are then made and controlled to the Census division estimates. In this manner, the monthly State employment and unemployment estimates will add to the national levels. The Regional estimates are simply the sum of their respective component divisions.
How are the estimates seasonally adjusted?
Seasonal adjustment occurs within the model structure, with the removal of the seasonal component.
