What Littleton's numbers say about electrical

Littleton counts 46,246 residents (2025 estimate), growing at a middle-of-the-pack 1.3% since 2020^[2]. It covers 12.6 square miles (3,665 residents per square mile, the 5th densest), spans Arapahoe County and Jefferson County and Douglas County, in ZIP codes 80120, 80123^[3].
