The town is primarily an agricultural community. The Kansas and Arkansas Valley Railway, now part of the Union Pacific Railroad system, established a depot at Lenapah in 1889, and a post office opened in the following year. There were 154 residents in the 1900 census, and 331 at statehood in 1907. The highest population was 434 at the 1920 census.
Oil and natural gas were discovered nearby after the start of the 20th century. Although this activity did not contribute much to the town's growth, it resulted in piping gas to Lenapah's homes and businesses.
Fire insurance maps drew every building, what it was made of and what it was used for, so insurers could price the risk of fire. Pick a year, then a sheet.
