[3] Sioux Center is notable for its Dutch heritage, agribusiness, and as the location of Dordt University.

[4] According to the United States Census Bureau, the city has a total area of 6.31 square miles (16.34 km2), all land.

The area within a ten-mile (16 km) radius of Sioux Center has been divided into sections of one square mile each.

The gravel and paved roads marking the sections do not swerve or contour for the slight hills or valleys.

Sioux Center commerce, like many smaller towns in northwest Iowa, is dominated by agribusiness.

[12] The quality of the farmland and its ability to produce high yields of corn and soybeans is the primary natural resource that propels the economy.

Other major local employers include the Interstates Companies, which specialize in the design and installation of electrical systems for industrial and commercial projects, and Pella, which manufactures windows and employs approximately 400 people in the local plant.

The BNSF Railway's main line runs parallel to U.S. Highway 75 through Sioux Center.

In 2012, Sioux Center was the first stop of RAGBRAI XL (Register's Annual Great Bicycle Ride Across Iowa).

[16] The Sioux County Youth Fair is held every year for about one week in the middle of July.

The fair is mainly focused on agriculture, but there are also live events like musical performances and various activities for kids.

Early in June the city hosts "Summer Celebration" which features a town theater production, car show, and cruise night as well as other miscellaneous events.

The All Seasons Center, which includes the Siouxnami Waterpark and indoor aquatic center, an ice skating arena, and spaces available for rent, is a mixed-use facility open to local residents and students of Dordt University.

Sioux Center is also home to Amistad Christiana, which is a Spanish-speaking congregation affiliated with the CRC and the RCA.

The orchestra also offers scholarships and opportunities for developing musicians from the local schools and colleges.

Dr. Henry Duitman directed the orchestra for the past 22 years and was recently hired as an Assistant Professor by Grand Valley State University in Allendale Charter Township, Michigan, leaving a conductor vacancy for the orchestra.

The kindergarten through 4th grade Kinsey Elementary School posted an all-time high enrollment of 477 in the fall of 2024.

Sioux Center Christian School educates approximately 538 students grades pre-K through 8th.

Dordt University and Northwestern College compete in a number of sports, including soccer, volleyball and basketball.

Its location changed many times over the years due to expanding demand and resource materials.

On July 23, 2003, a fire started due to arson and destroyed the library and $600,000 worth of materials in it.

[20] The library was moved to the community center while plans were drawn up for construction of a new building.

Completed in September 2008, the Sioux Center Library's new location opened the door to many services – private meeting rooms, an art gallery, and many computers available for public use.

Every year on a Saturday in December, more than 1,000 locations participate by laying wreaths out of remembrance and respect for America's servicemen and women.
