Title
PER CAPITA INCOME and AGGREGATE INCOME IN THE PAST 12 MONTHS (IN INFLATION-ADJUSTED DOLLARS) [Washington (State)--Seattle]
Description
Table from the American Community Survey (ACS)B19301 and B19313 per capita and aggregate income. These are multiple, nonoverlapping vintages of the 5-year ACS estimates of population and housing attributes starting in 2010 shown by the corresponding census tract vintage. Also includes the most recent release annually.King County, Washington census tracts withnonoverlapping vintages of the 5-year American Community Survey (ACS) estimates starting in 2010.Vintage identified in the "ACS Vintage" field.The census tract boundaries match the vintage of the ACS data (currently 2010 and 2020) so please note the geographic changes between the decades.Tracts have been coded as being within the City of Seattle as well as assigned to neighborhood groups called "Community Reporting Areas". These areas were created after the 2000 census to provide geographically consistent neighborhoods through time for reporting U.S. Census Bureau data.This is not an attempt to identify neighborhood boundaries as defined by neighborhoods themselves.Vintages:2010,2015,2020,2021,2022,2023ACS Table(s):B19301andB19313Data downloaded from:Census Bureau's Explore Census DataThe United States Census Bureau's American Community Survey (ACS):About the SurveyGeography & ACSTechnical DocumentationNews & UpdatesThis 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, seeAccuracy of the Data). The effect of nonsampling error is not represented in these tables.Data Processing Notes:Boundaries come from theUS Census TIGER geodatabases,specifically, the National Sub-State Geography Database (namedtlgdb_(year)_a_us_substategeo.gdb). Boundaries are updated at the same time as the data updates (annually), and the boundary vintage appropriately matches the data vintageas specified by the Census. These are Census boundaries with water and/or coastlineserasedfor cartographicand mappingpurposes. For census tracts, the water cutouts are derived from a subset of the2020 Areal Hydrography boundaries offered by TIGER. Water bodies and rivers which are 50 million square meters or larger (mid to large sized water bodies)are erased from the tract level boundaries, as well asadditionalimportantfeatures. For state and county boundaries, the water and coastlines are derived from the coastlines of the2020500kTIGER Cartographic Boundary Shapefiles.These are erased to more accurately portray the coastlines and Great Lakes.The original AWATER and ALAND fields are still available as attributes within the data table (units are square meters).The States layer contains 52 records - all US states, Washington D.C., and Puerto RicoCensus tracts with no population that occur in areas of water, such as oceans, are removed from this data service (Census Tracts beginning with 99).Percentages and derived counts, and associated margins of error, are calculated values (that can be identified by the "_calc_" stub in the field name), and abide by the specificationsdefined by the American Community Survey.Field alias names were created based on the Table Shells file available from theAmerican Community Survey Summary File Documentation page.Negative values (e.g., -4444...) have been set to null, with the exception of -5555... which has been set to zero.These negative values exist in the raw API data to indicate the following situations:The margin of error column indicates that either no sample observations or too few sample observations were available to compute a standard error and thus the margin of error. A statistical test is not appropriate.Either no sample observations or too few sample observations were available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls in the lowest interval or upper interval of an open-ended distribution.The median falls in the lowest interval of an open-ended distribution, or in the upper interval of an open-ended distribution. A statistical test is not appropriate.The estimate is controlled. A statistical test for sampling variability is not appropriate.The data for this geographic area cannot be displayed because the number of sample cases is too small.
