Iowa is an American state occupying an area of roughly 56,272 square miles and with a population of 3,145,711 individuals according to estimates from the US Census Bureau in 2017. Iowa has the 37th highest population density in the US with 55 individuals living in each square mile. Iowa joined the US in 1846 as the 29th state. Religion has been practiced in Iowa's territory for a long time due to the Native American population living in the area. Tribes such as the Hidatsa practiced a religion that placed great emphasis on ancestral spirits and the relationship between people and nature. The influx of Europeans into the state reduced the number of people who practiced the traditional religions. Several Native American communities such as the Sauk were moved out of the state further reducing the influence of the native religion. Today, Christians make up the largest religion in Iowa.
