Population over time

2 figures

Lyndon fell from 648 to 537 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.

GrEORGE Dennis Came from Trenton, New Jersey, and settled in Lyndon township prior to 1840. It required moral courage and back-bone for a young man to leave all the social advantages of an old settled country and come to the far West, where he would be almost entirely deprived of the society of young people. Mr. Dennis, though fond of fun, was manly, and very much respected by all who knew him. He married Miss Dodge, a sister of Job Dodge - now of Peru, Illinois - and is now living at Princeton, Iowa.
