After the Frankfurt–Mainz railway line was built, this formerly mostly agricultural village was transformed by the great number of large factories that located here, bringing along with them a great upswing in the town's population. In the decades following the Second World War, many businesses that were related to Frankfurt International Airport moved to the town. Kelsterbach is home to 16,565 people (). The town is an important centre for logistical service providers and chemical production. In 1952, it acquired the status of "town."
