Population over time
2 figuresHamburg fell from 1,187 to 890 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate, and an estimate published within five years of a census is left out. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

| September 2011 | Flood | Hamburg | $3,000,000 | Flooding along the Missouri River gradually improved over the area during September as releases from Gavins Point Dam were reduced. The river at Nebraska City, which reached a record crest of a little over 28 feet by the end of the June, had fallen to around 20.5 feet by the first of September and finally below its 18 foot flood stage during the evening of Sept. 28th. However, extensive flooding of farm fields, roads and highways that had occurred over the summer as levees near Hamburg and Percival failed persisted into September. The flooding caused the closure of 24 miles of Interstate 29 and Highway 2 into Nebraska City as well as other local roads and highways. After the flood waters receded, it was learned that Highway 2 near I29 had several areas of extensive damage, included a sink hole of 15 feet deep. Bridge approaches along I29 were damaged just north of the Missouri border. These roads remained closed in September. |

| June 2008 | Flood | Hamburg | - | Heavy rainfall on June 4th over much of southwest Iowa, and subsequent significant rain every few days for the next week or 10 days, pushed the Nishnabotna River out of its banks for a 2 week period beginning around 315 am CDT on June 5 and ending around 815 pm on June 18th.

However, Highway 275 near Hamburg and many county roads were closed for a time due to flood waters, and agricultural lowlands in the region were flooded. In addition, since both the Missouri and Nishnabotna Rivers were in flood, low areas that normally pumped water into those rivers were unable to do so adding to ponding and additional flooding after each rain. |
