The City of Caledonia has received its 2020 Census results, and there is reason for optimism. The City's 2020 Census population is 2,847. Although this number is slightly lower than the City's 2010 Census population of 2,868, it is significantly higher than what the Census estimated the population to be prior to the 2020 Census. The 2019 Census estimate for Caledonia was 2,754 based on American Community Survey data. (The higher 2020 Census population is not surprising because the MN State Demographer's Office acknowledged in 2018 correspondence that the ACS Census data was underestimating the average household size in Caledonia.)
Caledonia's 2020 Census results are even better when you take into account that these results don't include the second apartment building constructed by Twin Village Apartments, LLC, in Caledonia, which didn't open until fall 2020, which was after the April 1, 2020 deadline.
Based on the City's 2020 Census results and data from the MN State Demographer's Office, it appears that Caledonia's population has grown in recent years after declining after the 2010 Census and reaching its lowest point in 2017. Here are the MN State Demographer Office's estimates since 2012, which mirror the trend in active residential electric accounts, which dropped to 1,306 in 2016 but increased to 1,314 in 2017 and reached 1,341 in 2021.
