* Collier County successfully challenged their 1998 population estimate, but the results of the 1998 challenge were not incorporated into their original 1999 population estimate. The 1999 population estimate shown here reflects the results of the 1998 challenge.
The Bureau of the Census prepares annual estimates of total population for states, counties and all other units of general purpose government. States, counties and units of local government have the right to challenge the population estimates prepared by the Bureau of the Census under the provisions of Title 15, The Code of Federal Regulations, Part 90.
The regulations set out in 15 C.F.R. Ch. 1 Part 90 apply to any state or local government challenging Bureau of the Census estimates. Some of the more significant provisions are as follows:
A state or local government can request from the Bureau of the Census information about how to challenge their population estimate and the components used to derive the population estimate for their jurisdiction for the most recent year. Governments interested in this information may contact Population Division by telephone or letter:
Population Estimates Branch
U.S. Bureau of the Census
Federal Building 3, Room 2011
Washington, D.C. 20233
Telephone: (301) 457-2380
The materials mailed to the locality include appendices containing descriptions of the methodologies used in preparing county and subcounty population estimates. We also show the derivation of current year population estimates for a hypothetical county and local government.
If a governmental unit wishes to challenge a population estimate prepared by the Bureau of the Census, the governmental unit’s chief executive officer or highest elected official can initiate the challenge process for that governmental unit by:
Chief, Population Division
Bureau of the Census
Washington, D.C. 20233
Attention: Population Estimates Branch
The Chief, or the Chief’s designee shall review the challenge, the evidence supporting the challenge, and shall attempt to resolve the challenge.
In any instance, in which a local government and the Bureau of the Census cannot resolve a challenge through the informal procedures described above, the governmental unit may file a formal challenge.
