The population declined by more than 10% between 2010 and 2020, resulting in a lower tax base for the region and the unnecessary nature of a button on the city's website labeled 'new residents'. It is the home town of NBA player Scottie Pippen. The City of Hamburg crest has a picture of a gazebo, trees, cotton, and antelope.
