15. U.S. CENSUS DATA – 2010: DISSEMINATION OF DATA SUMMARY FILE 1 (SF 1): This file shows detailed tables on age, sex, households, families, relationship to householder, housing units, detailed race and Hispanic or Latino origin groups, and group quarters. Most tables are shown down to the block or census tract level. Some tables are repeated for nine race/Hispanic or Latino origin groups. The nine groups are (1) White alone, (2) Black or African American alone, (3) American Indian and Alaska Native alone, (4) Asian alone, (5) Native Hawaiian and Other Pacific Islander alone, (6) Some Other Race alone, (7) Two or More Races, (8) Hispanic or Latino; (9) White alone, Not Hispanic or Latino.

17. U.S. CENSUS DATA – 2010: DISSEMINATION OF DATA SUMMARY FILE 2 (SF 2 CONTINUED): This file shows detailed tables on age, sex, households, families, relationship to householder, housing units, and group quarters. Most tables are shown down to the census tract level. Tables are repeated by 141 race groups, 98 American Indian and Alaska Native tribes/tribal groupings, and 39 Hispanic or Latino origin groups. In order for any of the tables for a specific group to be shown in SF 2, the data must meet a minimum population threshold. The tables in SF 2 will be repeated for each group if there are at least 100 or more people of that specific group in a particular geographic area. (Release: December 2011-April 2012)

18. U.S. CENSUS DATA – 2010: DISSEMINATION OF DATA SUMMARY FILE 2 (SF 2): The SF 2 National Update File contains the same data tables as the state files, but the geographic levels include the U.S., regions, divisions, and other areas that cross state boundaries. (Release: May 2012) The SF 2 Urban/Rural Update File provides users with urban/rural population and housing unit counts (down to census tract) and characteristics for urbanized areas and urban clusters.

19. U.S. CENSUS DATA – 2010: DISSEMINATION OF DATA Congressional District Summary File – This file is a re-tabulation of Summary File 1 for newly redistricted Congressional Districts for the 113th Congress. State-based files will be released in January 2013 and every 2 years thereafter for states where congressional redistricting occurs. State Legislative District Summary File – This file is a re-tabulation of Summary File 1 for State Legislative Districts drawn following the 2010 Census.

Tables are repeated for the total population, the total AIAN population, the total American Indian population, the total Alaska Native population, and for numerous American Indian and Alaska Native tribes. In order for any of the tables for a specific group to be shown, the data must meet a minimum population threshold of at least 100 or more people of that specific group in a particular geographic area. (Release: April 2013)

21. U.S. CENSUS DATA – 2010: DISSEMINATION OF DATA Public Use Microdata Sample (PUMS) Files – The PUMS files contain state-level 2010 Census data containing individual records of characteristics for a 10 percent sample of people and housing units. Data will be included for age, sex, race, Hispanic or Latino origin, household type and relationship, and tenure data with identifying information removed, for PUMAs of 100,000 or more population. (Release: TBD) Of lesser importance than 2000?

22. Decennial Census In Census 2000, the census used 2 forms “short” form – asked for basic demographic and housing information, such as age, sex, race, how many people lived in the housing unit, and if the housing unit was owned or rented by the resident “long” form – collected the same information as the short form but also collected more in-depth information such as income, education, and language spoken at home Only a small portion of the population, called asample, received the long form.

24. The sample data are now collected in the ACS

25. Puerto Rico is the only U.S. territory where the ACS is conducted

26. 2010 Census will have a long form for U.S. territories such as Guam and U.S. Virgin Islands

30. 2 categories of group quarters:Institutional Non-institutional

32. Contrast with point-in-time estimates that describe the characteristics of an area on a specific date

34. American Community SurveyData Products Profiles Data Profiles Narrative Profiles Comparison Profiles Selected Population Profiles Tables Detailed Tables Subject Tables Ranking Tables Geographic Comparison Tables Thematic Maps Public Use Microdata Sample (PUMS) Files

37. Data for larger areas are available now and data for mid sized area will be available in December 2008

39. These estimates will cover the same small areas as Census 2000 but with smaller sample sizes

41. Cooperative Agreements Data available to at no cost to member institutions without any rights to redistribute or resell. Joint annual summer workshops to offer training on the new Census data products. One week training sessions held in 1991-1994 and 2001-2004 Census Bureau staff participated extensively in these courses Attracted both researchers and ICPSR Official Representatives who attended to learn how to provide assistance to faculty and students on their campuses

42. The Decennial In(di)gestion Census Data: Collected regularly since the 1960s. Number of files and bytes have grown exponentially with every new Census. Main reason for the rapid growth in the numbers of data files archived and disseminated by ICPSR. How much and how rapid?

43. The Decennial In(di)gestion

44. U.S. CENSUS DATA: DISSEMINATION OF DATA AND ICPSR Another access point, focused on the social science research community, to Census data and documentation Original Census data available from the 1960s onward as well as special samples created for earlier years TIGER Line Files American Community Survey Many of the newer files are available in a variety of formats: SAS SPSS Stata Ascii text files Tab-delimited

45. Special Census Subsets These files report population and housing data for national and specific sub-national geographical entities, for example: The entire nation Each individual state Counties Metropolitan Areas Places Census Tracts

46. Contextual File Based largely on Census data Provides information at the ‘county’ level in the U.S. (subunits of states numbering more than 3,100 in all) Contains data from other government and private sources at the same geographic level Under certain circumstances, can be merged with survey data

47. Contextual File - 2 Population by age, sex, race, and Hispanic origin Labor force size and unemployment Personal income Earnings and employment by industry Land surface form typography Climate Government revenue and expenditures Crimes reported to police Presidential election results Housing authorized by building permits Medicare enrollment Health profession shortage areas

48. Preservation ICPSR provides another location to preserve data and documentation files produced by the Census Bureau ICPSR keeps multiple copies of these files both at its home location at the University of Michigan and at other sites in the United States Copies are continually checked and updated when necessary Considerable interest in historical Census data by demographers, historians, and economists.

49. Current Happenings with ACS and Plans for Census 2010 Consulted with Collection Development Committee of ICPSR Council: Advised to continue ICPSR precedent of acquiring Census 2010 since the membership and the research community in general have traditionally come to ICPSR for their Census data needs. Suggestion that the data files need not be archived right away since all public-use data will be available directly from the Census Bureau. Emphases should center on archiving the most important Census data products when it could be best determined that final versions were created. The Committee also suggested that ICPSR consider holding training workshops on Census data once again as they did during the last decade and decide how best to finance them within the context of the Summer Program.

50. Current Happenings with ACS and Plans for Census 2010 Suggestion to study possibility that SDA functionality might work to produce subsets for Census data instead of creating specific data products to do so. Emphasis placed on partnerships and as an example working with the University of Minnesota Population Center and their National Historical Geographic Information System (NHGIS) which is expected to be able to produce subsets of 2010 Census data. Determine in general from membership and user community what value-added features might make sense for academic researchers as greater amounts of Census 2010 data become available.

51. Current Happenings with ACS and Plans for Census 2010 Select files archived at ICPSR beginning with 1996 ACS: Emphasis on PUMS files at first Greater interest in Summary Files as more data is released and, in particular, with the recent appearance of the first 5-year Estimates File covering calendar years 2005-2009

52. Current Happenings with ACS and Plans for Census 2010 TIGER files (Topologically Integrated Geographic Encoding and Referencing System) 2010 extracts containing geographic and cartographic information from the Census Bureau's MAF/TIGER® (Master Address File/Topologically Integrated Geographic Encoding and Referencing) database. These files support the 2010 Census Redistricting Data (P. L. 94-171) and the National Summary File of Redistricting Data/Summary File 1 releases. The files provide the digital map base for a Geographic Information System or mapping software. The files do not contain any mapping software.

53. Current Happenings with ACS and Plans for Census 2010 TIGER files (Topologically Integrated Geographic Encoding and Referencing System) All legal boundaries and names are as of January 1, 2010. The boundaries shown are for Census Bureau statistical data collection and tabulation purposes only; their depiction and designation for statistical purposes does not constitute a determination of jurisdictional authority or rights of ownership or entitlement. The geographic entity codes needed to link the Census Bureau's demographic data to the geography are included in the files. The TIGER/Line Shapefiles do not contain any demographic or economic data; data can be downloaded separately using American FactFinder.

54. Current Happenings with ACS and Plans for Census 2010 TIGER files (Topologically Integrated Geographic Encoding and Referencing System) Differences between shape files and line files Data stored at ICPSR through designated Web site Maintain archival copies as older versions of TIGER files cease to be distributed by Census Bureau http://www.icpsr.umich.edu/TIGER/index.html

55. ICPSR’s Public Archives

56. ICPSR’s Public Archives Three Differentiating Characteristics of a “Public Archive” Funding Sources Access Search

57. Funding Sources & Long Term Access ICPSR’s public archives are funded by entities including: Government agencies Foundations Other Organizations And if the funding ceases: ICPSR commitment to support access Access generally reverts to membership-only after some time period

58. Why are Funders using ICPSR? An Archive’s Reasons for Being Dissemination Infrastructure Systems & Search = technology, security, & metadata Data Community Base (700 immediate members to share with) Community Outreach/engagement expertise Preservation Fulfillment of Data Management Plan (Grant) Requirements Ability to Measure & Report Dissemination Statistics

59. Data Search within our Public Archives A search for data/documents from within a public archive defaults to searches of materials (data) within that archive A strategy to help one narrow their scope All materials are publicly available
