El Dorado | USA Arkansas

El Dorado is the administrative seat of Union County and is historically recognized as "The Original Boomtown" of Arkansas. It is situated in the timber-rich West Gulf Coastal Plain, just north of the Louisiana border.

Historical Timeline

Founded in 1843, El Dorado remained a small agricultural and timber village until January 10, 1921, when the Busey-Armstrong No. 1 well struck oil. This discovery triggered an immediate population explosion from 4,000 to over 30,000 residents, transforming the city into a major petroleum hub. The city later diversified into chemical manufacturing during World War II. The primary event shaping the current urban form was the 2017 launch of the Murphy Arts District (MAD), a multi-million dollar revitalization project aimed at converting the industrial historic core into a premier regional destination for arts and music.

Demographics & Population

The 2026 projected population is 16,657. The top three demographics are Black or African American (48.4%), White (45.0%), and Hispanic or Latino (5.9%). The median age is 36 years.

Ride-sharing (Uber/Lyft) is available but has lower vehicle density than Central Arkansas. The downtown core is highly walkable. South Arkansas Regional Airport (ELD) provides daily commercial flights to Dallas-Fort Worth.

Safety & "Red Zones"

The general safety level is moderate. Property crime rates are elevated in older residential blocks immediately east and south of the downtown district. The Union Square and Murphy Arts District are generally well-patrolled and safe for pedestrians during evening events. Standard urban vigilance is recommended near unoccupied industrial structures and older multi-family housing units.

Facts & Legends

El Dorado is home to the "El Dorado Promise," a unique scholarship program funded by Murphy Oil that pays the tuition and mandatory fees for local high school graduates to attend any accredited two- or four-year university in the U.S. A local legend claims that during the 1920s boom, the mud on the unpaved Main Street was so deep that a man’s hat was once found floating on a puddle; when a bystander picked it up, he discovered the man was still wearing it, riding his horse beneath the mud. A verified historical oddity is that the city produced more oil in 1921 than any other field in the United States, single-handedly pulling the state out of a post-WWI economic depression.
