https://www.neilsberg.com/insights/cohasset-ma-population-by-year/ I found this dataset by searching https://datasetsearch.research.google.com

It shows the population of the town Cohasset MA each year and how much it changes by.

The notable changes are in 2010 when 500 new people moves in and in 2020 where there was a drop in population, presumably due to COVID.
