Philadelphia, Indiana Demographics & Population 2026

A note before these figures: with a population of 431, Philadelphia's ACS estimates come from a small number of survey responses and carry wide margins of error. Individual percentages below — particularly rates that round to 0% or 100% — are approximations, not precise measurements. See data.census.gov for the published margins of error.

Data Sources & Methodology

All demographic data for Philadelphia, Indiana is sourced from the U.S. Census Bureau's American Community Survey (ACS) 2020–2024 5-Year Estimates. The ACS collects data from approximately 3.5 million households annually and pools five years of responses so that even small communities can be measured, though the margin of error widens as the population falls. Comparisons are made against Indiana state averages and national averages calculated from the same dataset. Rankings reflect the city's position among all 967 Census-designated places in Indiana.
