Title: Population Estimate, Total, Not Hispanic or Latino, Black or African American Alone (5-year estimate) in Plaquemines Parish, LA Series ID: B03002004E022075 Source: U.S. Census Bureau Release: County Population Estimates By Race And Ethnicity (Not a Press Release) Seasonal Adjustment: Not Seasonally Adjusted Frequency: Annual Units: Persons Date Range: 2009-01-01 to 2021-01-01 Last Updated: 2022-12-08 11:42 AM CST Notes: Data obtained from ACS Demographic and Housing Estimates, table DP05. 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 (https://www.census.gov/content/dam/Census/library/publications/2018/acs/acs_general_handbook_2018.pdf) for a more thorough clarification.
