Household Average Size by Zip Code (ZCTA5) — Indiana

NOTE: Gray indicates insufficient data or a suppressed estimate.

Northern Indiana, particularly the northeast region near Fort Wayne and areas around Elkhart-Goshen, displays notably higher average household sizes (3.0–3.5+), likely reflecting the significant Amish and large-family communities concentrated in that corridor. Central Indiana's urban core around Indianapolis trends toward smaller household sizes (1.5–2.2), consistent with higher concentrations of single-person households and smaller rental units typical of major metro centers. The southern third of the state generally falls in the moderate range (2.3–2.7), with pockets of very low household size appearing near college towns and isolated rural communities.
