18 Comparison Profiles Display Multiple Years Worth of Data and Indicate Where There are Statistically Significant Differences

19 Selected Population Profiles (SPPs) Display a Variety of Data for a Particular Race, Origin, Ancestry, or Country of Birth Group

25 25 Tables () 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 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. CV = Standard Error of Estimate Estimate

27 The Detailed Tables are the Foundation on Which the Rest of the Data Products are Built

52 52 New Data Products for 2008 by Topic

53 53 Deleted Data Products for 2008 by Topic

54 54 Modified Data Products for 2008 by Topic

55 55 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

56 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

57 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 estimates

58 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

59 59 Changes Due to New Content Nine new marital history tables Two new service-connected disability tables Six new health insurance tables

60 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
