How many people live in Trinidad, and is it growing?
The Census Bureau estimates that 317 people lived in Trinidad on July 1, 2025, down 6.2% since 2020, a steeper fall than California's (−0.5%). The Census Bureau's yearly estimates start from its own April 2020 base for Trinidad, 338, which differs from the 2020 Census count of 307: 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. The 2020-2024 American Community Survey, a five-year sample, puts the population at 347 (±98).

How reliable are the figures for Trinidad?
28 of the 57 figures for Trinidad 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.
