A highly accessible low-rise building with plenty of car parking spaces is home to the Johnston IA business center. The business center is easy to find from Interstates 80/35 and offers excellent business connections to the Greater Des Moines region where the key industries are financial services, logistics, biosciences and data centers. Most employment in Johnston itself is in the wholesale and retail sector, followed by healthcare and social services, then finance, insurance and real estate. Manufacturing makes up nearly 8% of the educated and productive labor force, closely followed by professional services. Nearly 49% of over 25s have a bachelor's degree or higher. Greater Des Moines is attractive for business because of its central geographic location, good roads and rail, and access to a quality IT workforce. Des Moines also has a Foreign Trade Zone, providing special services for businesses trading internationally, and a large commercial airport - Iowa's only port of entry.
