Iowa is the 26th largest state and the only state in the United States to be completely bordered on the east and west by rivers. Despite its northern latitude Iowa has a generally humid climate with abundant rainfall. This helped contribute to its early development as an agricultural powerhouse.
Iowa was originally focused primarily on agriculture but has since diversified to include a major manufacturing and industrial component as well as insurance and financial services. Agriculture remains a significant part of economic activity in Iowa. Iowa’s old pioneer history has left a wealth of landmarks and given rise to many museums and historic sites which are the state’s most popular tourist attractions.
Iowa has many smaller population concentrations throughout the state with most running east-west through the central areas. The eastern half of the state has slightly higher population levels than the west.
