The 2020 Census, the official count of every person in the United States, placed the population of Nebraska at 1,961,504. Over the decade 2010 to 2020, the state grew 7.4%, see Figure 1. However, population growth was uneven statewide, as 69 counties lost population while areas including Omaha, Lincoln, Grand Island, Kearney, and Columbus grew at stronger rates than previously projected (UNO CPAR, 2015). The release of the 2020 Census data provides the most accurate data to update population projections; however, not all data has been released at this time. Nonetheless, existing data on the fundamental aspects of population change, natural change and migration, are available. Moreover with aggregate population data for 2020, we can best fit a model of population change that reflects past dynamics. Nonetheless, all population projections should be viewed and applied with a great deal of caution as all projections are based on assumptions that may or may not occur. Moreover, as the time horizon for the projections increase, the likelihood of their accuracy decreases.
