This ready-to-use layer can be used within ArcGIS Pro, ArcGIS
Online, its configurable apps, dashboards, Story Maps, custom apps, and mobile
apps. Data can also be exported for offline workflows. Please cite the Census
and ACS when using this data.
Data Note from the Census:
Data are based on a sample and are subject to sampling
variability. The degree of uncertainty for an estimate arising from sampling
variability is represented through the use of a margin of error. The value
shown here is the 90 percent margin of error. The margin of error can be
interpreted as providing a 90 percent probability that the interval defined by
the estimate minus the margin of error and the estimate plus the margin of
error (the lower and upper confidence bounds) contains the true value. In
addition to sampling variability, the ACS estimates are subject to nonsampling
error (for a discussion of nonsampling variability, see Accuracy of the
Data). The effect of nonsampling error is not represented in
these tables.
Data Processing Notes:
- This layer is updated automatically when the
most current vintage of ACS data is released each year, usually in
December. The layer always contains the latest available ACS 5-year
estimates. It is updated annually within days of the Census Bureau's
release schedule. Click here to
learn more about ACS data releases.
- Boundaries come from the US Census
TIGER geodatabases. Boundaries are updated at the same time as
the data updates (annually), and the boundary vintage appropriately
matches the data vintage as
specified by the Census. These are Census boundaries with water
and/or coastlines clipped for cartographic purposes. For census tracts,
the water cutouts are derived from a subset of the 2010 AWATER (Area
Water) boundaries offered by TIGER. For state and county boundaries, the
water and coastlines are derived from the coastlines of the 500k TIGER
Cartographic Boundary Shapefiles. The original AWATER and ALAND
fields are still available as attributes within the data table (units are
square meters).
- Field alias names were created based on the Table
Shells file available from the American
Community Survey Summary File Documentation page.
