Lewis, Indiana Demographics & Population 2026

A note before these figures: with a population of 560, Lewis'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.

Population Overview

Lewis is a small community located in Indiana. The total population is 560. It ranks as the 488th most populous out of 967 Census-designated places in Indiana.

Age Demographics

The median age in Lewis is 24.2 years. This is 36% lower than the state median of 38.1 years. With 44.1% of the population under 18, Lewis has a notably young demographic profile, suggesting a family-oriented community.

Economy, Income & Housing

The poverty rate stands at 73.8%. This is 498% higher than the state poverty rate of 12.3%. With more than one in five residents living below the poverty line, economic hardship is a significant challenge for the community. The survey records no unemployed residents in Lewis, which reflects the size of the sample rather than a labor market without joblessness. Every occupied housing unit the survey reached in Lewis was renter-occupied. At this sample size that indicates no owner-occupied homes were captured rather than that none exist.

Race & Ethnicity

Every resident counted in Lewis was recorded as White (non-Hispanic). A figure of exactly 100.0% reflects a survey sample too small to capture the community's full composition rather than a precise measurement.

Education

0.0% of residents aged 25 and older hold a bachelor's degree or higher. This is among the lowest rates in the state, which may correlate with employment and income patterns. Nationally, 35.7% of adults hold at least a bachelor's degree. No surveyed resident aged 25 or older reported leaving school before earning a high school diploma, though a rate of exactly 100% reflects the limits of a small sample.

Data Sources & Methodology

All demographic data for Lewis, 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.
