15 CFR 90.5 - When an informal challenge may be filed.

§ 90.5 When an informal challenge may be filed.
An informal challenge to the population or per capita income estimates may be filed any time up to 180 days after the release of the estimates by the Bureau of the Census. Publication by the Bureau of the Census and simultaneous publication of a release notification in the Federal Register shall constitute release. A challenge to any estimate may also be filed any time up to 180 days from the date the Census Bureau, on its own initiative, revises that estimate.
If, however, a State or unit of local government has sufficiently meritorious reason for not filing in a timely manner, the Census Bureau has the discretion to accept the challenge.
