The number of immigrant residents in Iowa who are eligible to vote increased by 13.8 percent, or 7,743 people, between 2017 and 2018, according to new data released by New American Economy. The bipartisan immigration research and advocacy organization details the findings in this year’s edition of Map the Impact, an interactive map that quantifies immigrant contributions  and voting power across the country. This year, the map includes a new interactive data feature highlighting the most significant findings. According to the research, Iowa’s immigrant population grew by 15.2 percent between 2017 and 2018, helping to reverse the overall decline in statewide population, along with paying about $1.4 billion in taxes and holding $3.9 billion in spending power.
