Originator:U.S. Census Bureau

Title: 2018 American Community Survey: 5-Year Data, 2014-2018, Block Group Level, Selected Metrics

Abstract: American Community Survey (ACS) provides detailed demographic, social, economic, commuting and housing statistics based on continuous survey data collection. Data collected over the most recent 5 years are batched, summarized and published the following year. Summary tables compiled with 5-year data are available for all places and have approximately 20,000 variables from 900 tabulations.

Purpose: American Community Survey (ACS) provides detailed demographic, social, economic, commuting and housing statistics based on continuous survey data collection.

Time Period of Content Date: 2018

Currentness Reference: Five-year summary data are available annually, starting with the 2005-2009 period for Regional, County, and Community totals; the most recent five-year summary data cover the 2014-2018 period. Five-year summary data are available annually, starting with the 2006-2010 period for Station Areas. The Census Bureau no longer publishes three-year summary data, but previous releases remain available for Regional, County, and Community totals, starting with the 2005-2007 period and ending with the 2011-2013 period.

Section 2: Data Quality

Attribute Accuracy: Statistics produced for American Community Survey and included in ACS tables are survey-based estimates and are subject to error. The errors derive from research design (including instrument bias, data frame, and sampling), the survey data collection (non-response bias and response errors), and processing by the Census Bureau (data coding, compilation processes, and case weighting), as well as statistical inference error and uncertainty (which are related to sample size and variance within the measured attributes). US Census Bureau's report on "Accuracy of the Data" can be found at http://www.census.gov/acs/www/data_documentation/documentation_main/

Lineage: Data available annually, starting with period 2005-09 for 5-year data. Each annual vintage release uses the most recent year's TIGER geographic boundaries. Downloaded from NHGIS (nhgis.org) (see Citation for more information).
