Population of Swisher, IA Last official estimated population of Swisher city (Johnson County**, Iowa state) was 932 (year 2014) [1]. This was 0% of total US population and 0.03% of total Iowa state population.
The Omaha metro area includes Douglas, Sarpy, Cass, Washington and Saunders Counties in Nebraska and Pottawattamie, Mills and Harrison Counties in Iowa. Collectively, the area has been growing over the past decade by about 1.2 percent a year, which would give the metro a population of more than 1 million by 2023. Even projecting forward with the slightly smaller growth rate seen over the past 25 years, Omaha would still top 1 million by that year.
