In 1900, Iowa’s rural population was just shy of 1.7 million, with almost three-fourths residing on farms or in small towns. However, with the exception of the 1990s, Iowa’s rural population has declined in every census over the last 110 years, as shown in Figure 1. By 2010, only 36% of Iowans remained in rural areas.
