Census, U.S., 20190108, 2010 Tracts joined to ACS 2013-2017 table: Household Income In The Past 12 Months (In Inflation-Adjusted Dollars) (Black Or African American Alone Householder): King County, King County, WA.
US Census American Community Survey 2013-2017
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_b19001b_householdincomeblack), 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.
Covers all of King County
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.
