Sargent is located in Custer County off of US Hwy 183 north of Ansley, just north of the Loup River.
The population estimate for July 1, 1998 was 661, a decrease of 49 since 1990.
A post office, named "Sargent," was established a mile east of the present town in 1879. When Ezra Savage and Joseph Thomas started the town in 1882, the postmaster, Mrs.George Sherman, agreed to move to the new location if they kept the Sargent name.
A campground /R.V. park is available at Sargent, just 9 miles west of the Comstock Windmill Site on the corners of Broadway and Jesse Streets.
