Marengo fell from 7,648 to 7,568 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.

History of McHenry County, Illinois : Together with Sketches of Its Cities, Villages and Towns : Educational, Religious, Civil, Military, and Political History : Portraits of Prominent Persons, and Biographies of Representative Citizens, Also a Condensed History of Illinois .., published 1885 names this settlement in its chapter on Marengo Township. These are the passages that mention it, exactly as the scans read.

This township is surpassed by none for its rich lands and splendid improvements. Go where you will and nothing but beautiful farms under the highest state of agriculture greets the eye, together with the finest of residences and farm buildings. Nowhere in all the country do we see such marked evidence that enterprise has kept perfect pace with time and all its wondrous changes and improvements, and rapid strides in the interests of civilization. The township consists chiefly of prairie land which is so well drained by Nature's own provision that every foot is tillable and productive. For grain and stock raising the township is equally well adapted. The dairying business has grown to be quite an industry here, while thousands of bushels of grain are yearly raised. The township is scarce of timber, except along the branches of streams where some small timber is found, it being more plenty in early times than at present. Kishwaukee Creek crosses sections 25, 26, 27, 28, 29 and 30, and is joined on the east by Rush Creek. This is the only township in the county that can boast of a stone quarry. It is situated on section 31, and has proved to be a marked benefit. From it was taken the stone to build the school-houses at Marengo and Union. Near the southern line the railroad traverses the township from east to west, and the location of the depot at the village of Marengo makes an advantageous point for ship ping the products of adjoining townships.
