What does this data set describe?

Title:
2010 Census SF1 table: Urban and Rural - Total Population for Block Groups
Abstract:
US Census 2010 SF1 data table for: Urban and Rural - Total Population subject area related to Block Groups. This physical table contains 6 items representing 1 subcategory(s) (also know as logical table(s)).These logical table category(s) encompass the following topics: p2-Urban And Rural (6); . The value (letter number combination) before the dash is the logical table name,which is also the prefix for the items in that logical table. The value inside the ( ) after the description of the logical table is the number of items in that logical table. If the description of the logical table is all in uppercase this logical table is also provided as a customized lyr file (blkgrp10_area_sf1p02.lyr) where these items have been joined to the Census Block Groups featureclass to help meet defined interest or business uses. If the table name and description are all in mixed case, this logical table is of less importance to county business and is available only as a table, and not as a lyr file. However any SF1 table can be joined to the appropriate Census geography on the GEOID relationship.

    Entity_and_Attribute_Overview:
    There are 6 items in this physical table. Each item is identified with the 10 character alpha-numeric code provided by the Census Bureau. In addition, when stored in an ESRI GDB, each table item is provided with an alias constructed from the field description provided with the data tables. For some items, these aliases are lengthy. To minimize the length of the alias strings where possible the following abbreviations were used. Abbreviations used: pop = population; Wh = White; BlAfAm = Black or African American; NaHaPaIs = Native Hawaiian and Other Pacific Islander; HispLat = Hispanic or Latino; SOR = Some Other Race; AmInAlNa = American Indian and Alaska Native; hsehlds = households; hsehlder = householder; grp = group; qtrs = quarters; occ = occupied. The full unabbreviated versions of the descriptions are available in the metadata for this table.

Why was the data set created?

Provides Standard Form 2010 Census counts for People topics.


How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    Date: 01-Aug-2011 (process 1 of 1)
    Data tables for Washington were downloaded from the Census website. A geographic cross-reference table was constructed in Access and populated with the GEOID values necessary for each census geography. This table was then filtered for only King County records. A script was created to filter only King County records from each of the 47 data tables. The data dictionary provided by the Census was formatted as a spreadsheet and denormalized. This was then imported into a table to drive other processing tasks. First, a script was created to build each of the data table shells in a ESRI geodatabase, assigning an alias to each field name based on the item description. Next, another script was used to import the text data files into each structure. Finally another script was created to join the GEOID table with each data table and filter out appropriate Block, Block Group, Tract, and Place extracts based on SUMLEVEL. The spreadsheet data dictionary was also used with a script to generate FGDC xml metadata for each table and selected LYR Files.

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    See section in SF1_2010.pdf document available through link in Supplemental Info section

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    Covers all of King County

  5. How consistent are the relationships among the observations, including topology?

    In the entire SF 1 series, there are 47 physical tables spanning 331 logical tables. Not all tables are related to each geography (place, tract, block group and block). Of the 331 tables, 269 are population tables and 62 are housing tables. Of the 269 population tables, 177 relate down to the block level, 82 relate down to the tract level and 10 relate to the county level. Of the 62 housing tables, 58 relate down to the block level, 4 relate down to the tract level and none relate to the county level. Some tables are repeated by each major race and Hispanic or Latino groups: 14 population tables and 4 housing tables are shown down to the block level and 5 population tables are shown down to the tract level.
