Detailed Tables (Base Tables)

• Basic distributions of characteristics
• The foundation upon which other data products are
  built
• Show estimates with its margin of error. By
  adding and subtracting the margin of error from
  the point estimate, you produce the range around
  it called the confidence interval. (there is 90
  certainty that the true answer lies within the
  listed upper and lower percentages).

26
Detailed Tables are Subject to Filtering
The 1-year and 3-year detailed tables are not
published (i.e., filtered out) if the median
coefficient of variation (CV) for the table is
.61 or higher.

Most of the Data Product Changes Stem From
Changes to the Questionnaire

• 3 New Topics
• Marital History
• Health Insurance
• Service-Connected Disability
• Notable changes to many other topics including
• Disability
• Employment
• Relationship
• Educational Attainment and Grade Enrolled
• Year of Naturalization
• Food Stamps

55
56
Changes to the Disability Questions

• Over half the 2008 data product changes were due
  to changes to the disability questions and
  instructions
• These changes were significant enough that 2008
  disability estimates are NOT comparable with
  previous disability estimates
• This is true even for the estimate of with or
  without a disability

56
57
Changes to the Disability Products

• As a result, we deleted all 83 old disability
  tables and replaced them with 33 new tables
• We also replaced tables that cross with
  disability
• Grandparents (1)
• Veterans (2)
• SNAP/Food Stamps (1)
• Employment (3)
• Many of the new disability tables will look
  exactly like the old tables but will carry a
  different table ID and a footnote to let users
  know that the estimates are not comparable with
  previous years
• Because of the break in series, there will not be
  any disability estimates in the 3-year data
  products until 2011 when we publish the 2008-2010
  estimates

57
58
Other Changes Due to Revised Content

• Fifteen new tables for expanded relationship (3),
  grade enrolled (10), and educational attainment
  (2)
• Two new foreign born tables displaying data from
  the new year of naturalization write-in
• Two employment tables deleted because the new
  categorical weeks worked question does not allow
  the calculation of aggregate or mean weeks worked
• One SNAP/Food Stamp table deleted because we no
  longer collect SNAP/Food Stamp amount

58
59
Changes Due to New Content

• Nine new marital history tables
• Two new service-connected disability tables
• Six new health insurance tables

59
60
Other Changes

• Twelve ancestry tables modified due to the
  creation of a new Irish-Scotch code
• Twenty-five industry tables modified due a
  regular update of the industry codes
• Two new tables for multigenerational households
• Three new detailed occupation by median earnings
  tables published only for the nation
• Most of the remaining changes involve new or
  deleted collapsed or race-iterated tables
