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:

- 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.
