Title: Income Inequality in Major County, OK Series ID: 2020RATIO040093 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 10:42 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 12.275362318840580 2011-01-01 13.507439173814108 2012-01-01 14.469438083494804 2013-01-01 13.710350089005680 2014-01-01 13.111959287531807 2015-01-01 15.470507039661360 2016-01-01 15.146119125586335 2017-01-01 13.698205289672543 2018-01-01 12.572144067172424 2019-01-01 13.245702005730658 2020-01-01 11.600257990540348 2021-01-01 9.750514050719671 2022-01-01 10.605495134516314
