Community Overview

Newcomb sits within the Navajo Nation in northwestern New Mexico, serving a predominantly Native American community across 388 square miles of San Juan County. Of the 1,641 residents, 95% (1,566 people) are Native American. With a median age of 40.3 years and an average of 3.0 people per household, Newcomb shows the multi-generational family structure typical of Navajo communities.

Geographic Context and Mail Delivery

Mail reaches this remote territory through a single highway contract route along Highway 491 South. The community post office maintains 486 PO Boxes for 551 households, an 88% adoption rate. This isn't a PO Box Only Zone, meaning limited highway delivery exists, but most residents rely on boxes at the post office. Only one street appears in USPS addressing records across the entire 388 square miles.

Economic Context

The economy centers on public services and transportation. Of working residents, 318 work in transportation and warehousing, 230 in public administration (likely Navajo Nation government), and 262 in education and healthcare. Federal government employs just 7 workers. Nearly half of workers (47%) work from home, and 166 carpool to jobs, patterns that reflect the rural distances and limited local employment.

Income and education levels show economic challenges common in rural tribal areas. Median household income stands at $36,625, with per capita income of $22,045. Only 11% of adults hold bachelor's degrees. Median home value is $25,600, and median rent is $625. About 75% of housing (413 of 551 occupied units) is owner-occupied. The community includes 123 mobile homes and 748 older housing units (built before 1939 based on total stock of 646).

The Post Office as Community Connection

The post office serves as a critical connection point for government documents, packages, prescriptions, and correspondence across territory where addressing infrastructure is minimal. That 486 families maintain boxes demonstrates the facility's role as the community's mail lifeline.
