Title American Community Survey 5-Year Summary File
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 December.
Purpose 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 December. Summary tables compiled with 5-year data have approximately 20,000 variables from 900 tabulations. The published Census statistics have been recompiled by Metropolitan Council, with new field names, in order to accomplish definitional and categorical consistency between Census 1990, Census 2000, and ACS.

Section 2 Data Quality Information Top of full metadata Top of page
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/
Logical Consistency The published Census statistics have been recompiled by Metropolitan Council, with new field names, in order to accomplish definitional and categorical consistency between Census 1990, Census 2000, and ACS.
Completeness Entire seven county geographic area is covered.

Lineage Data available annually, starting with period 2005-09. Each annual vintage release uses the most recent year's TIGER geographic boundaries. Historical data for geographies retired before 2009 is not available.

Entity and Attribute Overview
Attributes for Tabular Data:   

CO_CODE: 3 digit FIPS and state standard county ID code
003 = Anoka County
019 = Carver County
037 = Dakota County
053 = Hennepin County
123 = Ramsey County
139 = Scott County
163 = Washington County

CTU_CODE: 5 digit FIPS55 'Place' code for CTU. As of 2010, these codes have been retired by the
federal government. They are replaced by the GNIS codes below. Note that for townships
that wholly incorporate into cities, the same FIPS55 code for the former township will
usually be used for the new city. Conversely, GNIS creates a new ID for the new city.

CTU_ID: The Geographic Names Information System (GNIS) federal unique identifier for each city,
township or unorganized territory.

COCTU_ID: 11 digit identifier for the combination of county and CTU (concatenation of CO_CODE
and CTU_ID_CEN).

CTU_NAME: Name of the city, township or unorganized territory, e.g. Benton Twp., Blaine.

SUMLEV: Census summary level of the data.

YEAR: Year of the data collection.

DATASOURCE: Data source.

DATASOURCE DESC: Data source description.

SUBJECT_AREA: Subject area.

SUBJECT_AREA_DESC: Subject area description.

SUBJECT_LEVEL_DESC: Subject level description.

DENOMINATOR_LEVEL_DESC: Universe of the data.

MEASURE: Total for a part of a subject area.

DENOMINATOR: Total for all parts of a subject area.
