ARCGIS LYR File - ACS_B19001G_AREA_HOUSEHOLDINCOME2RACES: 2010 Census Tracts joined to B19001G business table. Business table is US Census American Community Survey (2013-2017) data table for: INCOME subject area. Provides information about: HOUSEHOLD INCOME IN THE PAST 12 MONTHS (IN INFLATION-ADJUSTED DOLLARS) (TWO OR MORE RACES HOUSEHOLDER) for the universe of: HOUSEHOLDS WITH A HOUSEHOLDER WHO IS TWO OR MORE RACES. 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 17 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_B19001G_HOUSEHOLDINCOME2RACES. 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.
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_b19001g_householdincome2races), 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.

Each value for a given item is an estimate (E) of that value. Adjacent to each E item is a M (margin of error) value. The margin of error value describes the possible range of error in the estimage value. The upper and lower bounds describethe 90% confidence interval for this value, i.e., there is 90% chance that the actual value of the item will fall between the bounds defined by the estimage - the margin of error and the estimage + the margin of error. In addition to sampling variability, the ACS estimates are subject to nonsampling error.
Each 2010 Census Tract has one record joined from the business table. Each table record contains the estimate for that item definition adjacent to the margin of error for that value.

1. In ArcMap, each ACS table is joined to TRACTS_AREA on the GEOID item. This join is preserved by saving the joined object out as a uniquely named layer file.

Entity_Type_Definition: ArcGIS layer file
Entity_Type_Definition_Source: US Census
Each table item name (field name) is a 9 or 10 character alpha-numeric string (such as E03002022) that provides information about whether the item is an Estimate value or MOE value (E or M, respectively), which table the item is associated with (next 5 or 6 characters), and the item position in the larger data sequence (last 3 numbers). Actual table names are 6 or 7 characters, but for use in item names are stripped of their leading letter so that the item name uses a modified identifier of 5 or 6 characters, depending on table. This was done so that any item name is comprised of the leading E or M (1 char) plus the modified table identifer (6 char, maximum) + the item position (3 char), totaling 10 characters, the maximum allowed to create unique table items that are dbf compliant (maximum 10 characters). Users will find the the common language alias, associated with each item useful in determining the identify of a field value. Each estimate value (stored in E item) is paired with a margin of error value stored in the M item for the same item number. Some data tables contained non-numeric characters, either representing the entire field value or appended to a integer value. Where the symbol was appended to a valid value, (such as + and -, to indicate that the value occurs in the upper and lower range of the open ended distribuiton) the symbol was removed. Where the symbol appeared by itself (i.e., -) the symbol was removed and the cell was left blank. Other non-integer symbols include asterisk(s) and 'N' and (X), where each symbol represents a different level of insufficient statistical viability; in these cases the symbols were removed and the fields left blank. More information can be found in the documents referenced in the Supplemental Information section. Edits made to values in specific tables can be found in the Supplemental Information document titled acs1317_ReviewRawDataContentReport.xls
