Liberty Center sits in rural Warren County, Iowa, with a population of just 76 residents across 3.6 square miles. This is a PO Box Only Zone. No alternative mail delivery exists, so all 44 households rely on either the single rural carrier route or the post office's 21 PO Boxes.
With a median age of 53.7 years and no children under 18, Liberty Center functions as a quiet community of older adults and couples. The small household size of 1.7 people reflects this demographic. About half of the households (48%) use PO Boxes, while the rest receive rural route delivery along streets like Tyler Street (11 addresses), 160th Avenue (9 addresses), and Main Street.
Despite its size, the community shows economic stability. Median household income reaches $82,708, and 58% of adults hold bachelor's degrees or higher. These numbers are unusually high for a rural Iowa hamlet, suggesting retired professionals rather than agricultural workers. The workforce includes transportation workers (26 people), government employees (17), and service workers (17).
The Liberty Center Post Office has operated since before October 2004, when USPS began tracking ZIP introduction dates. The alternate name "Liberty CTR" was recognized in May 2005 as a valid mailing address. Homeownership dominates, with 86% of the 44 occupied homes owner-occupied rather than rented.
Street names combine numbered county avenues with traditional small-town streets like Tyler, Main, Liberty, and Shaw.
ZIP Code 50145 has 76 residents and 44 households (average 1.73 persons per household).

Largest groups are White (93.4%, much higher than the state average of 84.5% and well above the national average of 61.6%) and Hispanic or Latino (1.3%); Hispanic or Latino residents make up 1.3%, which is much lower than the national average (18.7%).
