Merrill population history
Open historical explorerThe six July 1 estimates in the table belong to one consistent Vintage 2025 series. The Census Bureau revises earlier years when it releases a new vintage; a figure from an older publication may differ from the value below.

Why is the April 2020 estimates base different from a census count?
The PEP estimates base here is 863 residents on April 1, 2020. It incorporates the Census Bureau’s corrections and geographic revisions and serves as the starting point for this annual series. It is not labeled an original 2020 census count. The chart starts at July 1, 2020, so its five-year change uses two July observations. Read about measurement types.

From the April 2010 estimates base to the April 2020 census count, Merrill lost 19 residents (-2.3%). These Census Bureau intercensal estimates use 2020 boundaries and were released in November 2024.

The April 2020 census count (823) and the Vintage 2025 April 2020 base (863) differ by 40. The gap comes from boundary changes and the Census Bureau’s revised 2020 base, not population change, so measure growth within one series. Source and download
Growth and density
Between July 1, 2020 and July 1, 2025, Merrill gained 1 residents, a 0.12% increase. The annualized change over these five elapsed years was +0.02%. Annualized change is a summary of the interval; it does not imply that the population changed at that rate in every year.
The 2025 Gazetteer reports 0.48 square miles of land. Dividing the July 1, 2025 population by that compatible land area gives 1,805.1 people per square mile. Water area is excluded. Density depends on geographic boundaries. It describes this entire place, rather than a typical neighborhood or built-up area.
Calculations use unrounded source values. Population counts are displayed as integers, percentages to two decimals and density to one decimal. Calculation methods · Growth calculator
