How many people live in Mineral Township, and is it growing?
The Census Bureau estimates that 434 people lived in Mineral Township on July 1, 2025, down 2.5% since 2020, a steeper fall than Illinois's (−0.8%). The Census Bureau's yearly estimates start from its own April 2020 base for Mineral Township, 445, which differs from the 2020 Census count of 477: the estimates follow the place as the estimates program defines it today (its present boundaries, and for a consolidated city-county the area the program assigns it), so the change since 2020 is measured from that base.

How reliable are the figures for Mineral Township?
24 of the 57 figures for Mineral Township on this page carry a coefficient of variation over 40% and are marked with a ring: they come from a small sample, so read them as rough.
The American Community Survey samples about one household in eight over five years, so every figure is an estimate with a 90% margin of error (shown under each value). A ring marks an estimate whose coefficient of variation is over 40%. A change is called only when the gap between the two periods is larger than their combined 90% margin (the square root of the sum of the two squared margins), the Census Bureau's test.
