The population percent change expresses the difference between the population estimate from the most current five year data collection period and the previous estimate as a percentage of the previous estimate. The previous estimate is the estimate from the previous non-overlapping five year data collection period.

This measure counts the number of cities that have experience growth from the previous estimate from non-overlapping 60 month data collection period.

This measure counts the number of cities that have experience population decline from the previous estimate from non-overlapping 60 month data collection period.

This measure counts the number of counties that have experience a population decline from the previous estimate from non-overlapping 60 month data collection period.

Measure reports the median age of the State of Iowa's population based data collected over a 60 month period. Data is from the American Community Survey, Five Year Estimates, Table B01002.

This residual represents the change in population that cannot be attributed to any specific demographic component. See the Population Estimates Glossary at https://www.census.gov/programs-surveys/popest/about/glossary.html. // Net international migration in the United States includes the international migration of both native and foreign-born populations. Specifically, it includes: (a) the net international migration of the foreign born, (b) the net migration between the United States and Puerto Rico, (c) the net migration of natives to and from the United States, and (d) the net movement of the Armed Forces population between the United States and overseas. // The estimates are based on the 2010 Census and reflect changes to the April 1, 2010 population due to the Count Question Resolution program.// The Office of Management and Budget's statistical area delineations for metropolitan, micropolitan, and combined statistical areas, as well as metropolitan divisions, are those issued by that agency in July 2015. // For detailed information about the methods used to create the population estimates, see https://www.census.gov/programs-surveys/popest/technical-documentation/methodology.html. // Each year, the Census Bureau's Population Estimates Program (PEP) utilizes current data on births, deaths, and migration to calculate population change since the most recent decennial census, and produces a time series of estimates of population. The annual time series of estimates begins with the most recent decennial census data and extends to the vintage year. The vintage year (e.g., Vintage 2016) refers to the final year of the time series. The reference date for all estimates is July 1, unless otherwise specified. With each new issue of estimates, the Census Bureau revises estimates for years back to the last census. As each vintage of estimates includes all years since the most recent decennial census, the latest vintage of data available supersedes all previously produced estimates for those dates.
