Title: Income Inequality in Clinton County, IA Series ID: 2020RATIO019045 Source: U.S. Census Bureau Release: Income Inequality (Not a Press Release) Seasonal Adjustment: Not Seasonally Adjusted Frequency: Annual Units: Ratio Date Range: 2010-01-01 to 2022-01-01 Last Updated: 2023-12-07 11:33 AM CST Notes: This data represents the ratio of the mean income for the highest quintile (top 20 percent) of earners divided by the mean income of the lowest quintile (bottom 20 percent) of earners in a particular county. Multiyear estimates from the American Community Survey (ACS) are "period" estimates derived from a data sample collected over a period of time, as opposed to "point-in-time" estimates such as those from past decennial censuses. ACS 5-year estimate includes data collected over a 60-month period. The date of the data is the end of the 5-year period. For example, a value dated 2014 represents data from 2010 to 2014. However, they do not describe any specific day, month, or year within that time period. Multiyear estimates require some considerations that single-year estimates do not. For example, multiyear estimates released in consecutive years consist mostly of overlapping years and shared data. The 2010–2014 ACS 5-year estimates share sample data from 2011 through 2014 with the 2011–2015 ACS 5-year estimates. Because of this overlap, users should use extreme caution in making comparisons with consecutive years of multiyear estimates. Please see "Section 3: Understanding and Using ACS Single-Year and Multiyear Estimates" on publication page 13 (file page 19) of the 2018 ACS General Handbook for a more thorough clarification. https://www.census.gov/content/dam/Census/library/publications/2018/acs/acs_general_handbook_2018.pdf DATE VALUE 2010-01-01 9.585779215776904 2011-01-01 9.883001696745334 2012-01-01 10.702032882481575 2013-01-01 11.710306636912142 2014-01-01 12.061079774375504 2015-01-01 12.334345756033493 2016-01-01 12.174276893077673 2017-01-01 12.202452531645570 2018-01-01 11.271660850842675 2019-01-01 11.605587263442475 2020-01-01 11.464076828651889 2021-01-01 11.058621121121120 2022-01-01 11.222614217675074
