Title: 2010 Tracts joined to ACS 2013-2017 table: Educational Attainment By Presence Of A Computer And Types Of Internet Subscription In Household

Feature Type: ArcGIS LYR file
Abstract: ARCGIS LYR File - ACS_B28006_AREA_EDUTYPEINTERNETHSHLD: 2010 Census Tracts joined to B28006 business table. Business table is US Census American Community Survey (2013-2017) data table for: COMPUTER AND INTERNET USAGE subject area. Provides information about: EDUCATIONAL ATTAINMENT BY PRESENCE OF A COMPUTER AND TYPES OF INTERNET SUBSCRIPTION IN HOUSEHOLD for the universe of: HOUSEHOLD POPULATION 25 YEARS AND OVER. These data are extrapolated estimates only, based on sampling; they are not actual complete counts. This Layer File contains both the Estimate value in the E item for the census topic and an adjacent M item which defines the Margin of Error for the value. The Margin of Error is the plus/minus range for the item estimate value, where the range between the Estimate minus the Margin of Error and the Estimate plus the Margin of Error defines the 90% confidence interval of the item value. Many of the Margin of Error values are significant relative to the size of the Estimate value. This table contains 19 item(s) extracted from a larger sequence table. This extracted subset represents that portion of the sequence that is considered high priority. Other portions of this sequence that are not included can be identified in the data dictionary information provided via the link in the Supplemental Information section. This table information is also provided as a stand-alone table named: ACS_B28006_EDUTYPEINTERNETHSHLD. Both the table and customized layer file name do not contain the year descriptor (i.e. 2013-2017) for the current ACS series. This is intentional in order to maintain the same table\layer file name in each successive ACS update. The alias of each item's (E)stimate and (M)easure of Error value stores the vintage information as beginning YY and ending YY, i.e., 'E1317' and 'M1317' followed by the rest of the alias name. In this way users of the data tables or layer files that support field aliases can determine which ACS series is being represented by the current table contents. The next 5-year sample of ACS, representing the current year minus 1, becomes available in December of each year. For example, the next series - 2014 through 2018 - will become available at the end of 2019. The new 2017 data will be posted to the Spatial Data Warehouse, and hosted on the Open Data site by January 2019. The previous series of data is retired to the Historical Data Library geodatabase (according to the ACS series end date) from where it can be accessed if needed. The description of the attributes that are in the business table joined to TRACTS10_AREA are not repeated here in this layer file metadata. The table metadata, accessible from the link in the Supplemental information section, can be viewed to review the item descriptions.
Purpose: Provides a relationship between the 2010 Census Tracts geometry and associated business table data. The same business table information can be obtained from the geodatabase or dbf table, (acs_b28006_edutypeinternethshld), but associating the table (via a join on the GEOID item) with the Tracts geometry allows creation of a customized layer file which can be symbolized. This relationship provides a multi-year statistical estimate for selected demographic, social, economic and housing characteristics. These estimates represent concepts that are fundamentally different from those associated with sample data from the decennial census long form. Further, because ACS data are collected continuously, they are not always compatible with data collected from the decennial census. This data is a sample size based on a 5-year period. The sample size based on the 5 year period estimates is still smaller than the decennial census, resulting in larger standard errors. A five year estimate represents data collected over a 60 month period. Therefore ACS estimates based on data collected from this 2013-2017 period should not be labeled as '2015' estimates, even though that is the midpoint of the 5-year period.
