Population estimates are prepared as of July 1st of each year. 

Preliminary estimates are released around November 15th each year. We send a letter to state and local jurisdictions and post them here. 

Certified estimates are posted on December 15th.

Supplemental reports are published quarterly, and are posted here two weeks after the end of each quarter. These reflect changes in population due to annexations and other revisions.
