thresholds as standard tracts and block groups

off-reservation CDPs

Redistricting Data Program
• Enacted by Congress in December 1975, Public Law
94-171 requires the Census Bureau to provide states
with the opportunity to specify geographic areas for
which they wish to receive census population tabulations
• Requires the Census Bureau to tabulate decennial
census population data, according to the geographies
submitted in the state plan, no later than April 1, 2011
Phase 1 –
State Legislative District Project (SLDP)
(2004-2006)
• Collection of State Legislative District (SLD)
boundaries (House and Senate)
• 100% participation
• Completed in January 2007
Phase 2 –
Voting Tabulation District (VTD)
Block Boundary Suggestion Project (BBSP)
(2007-2010)
• This phase combined the option to
– submit voting district boundaries for 2010 Census
tabulation block boundaries
– suggest 2010 Census tabulation block
boundaries
• Participation in both components or just one
• Verification phase included for all
components (VTD/SLD/CD)
Phase 3 –
Delivery of the Decennial Census 2010
Redistricting Data
(2010-2011)
In accordance with 13 U.S.C. 141(c)
the Governor and legislative leaders of both
the majority and minority parties will receive
population counts for standard geographies
down to the census tabulation block no later
than April 1, 2011
Data Delivery
• Delivery of population counts to the President
by December 31, 2010
• TIGER/Line Shapefiles to states in late
November 2010 through January 2011
• P.L. data to states February through March 2011
– Must be delivered by April 1, 2011
Phase 4 –
Collection of Post-Census 2010
Redistricting Plans
(2012-2013)
• The Census Bureau will collect from each state
newly drawn congressional and legislative district
plans
• The Census Bureau will re-tabulate 2010 census
data for these newly drawn boundaries
• The American Community Survey (ACS) will also
tabulate ACS data for these newly drawn boundaries
Phase 5 –
Evaluation and Recommendations
(2012-2014)
• Evaluation of Census 2010 Redistricting Data
Program
• Recommendations for the 2020 Census
• “View from the States”
– Final phase will result in the 4th edition with
recommendations for the 2020 Census
Post-2010 Census Geographic Areas
Urban Areas: Census 2000
Overview
•
•
•
•
ZCTAs - ZIP Code Tabulation Areas
Urban Areas – Urban/Rural
TAZs - Traffic Analysis Zones
PUMAs - Public Use Microdata Areas
ZIP Code Tabulation Area Delineation
• 5-digit ZCTAs only for Census 2010
– No 3-digit ZCTAs
• 2010 census blocks will form the
“building blocks” for ZCTAs
• ZCTAs will be defined only for areas with
residential ZIP Codes
– Will not cover the entirety of the nation
• ZCTAs will more closely approximate ZIP
Codes
Initial ZCTA Line Insertion
Software
An example of block and MSP address configuration where a block split should occur
The most frequently occurring
ZIP Code in this block is
associated with only 60% of
the addresses.
Initial ZCTA Line Insertion
Software
Example of adding a ZCTA split line to a block
ZCTAs Delineation Schedule
• Spring 2010: Added non-visible edges to
MAF/TIGER Database
• November 2010 - March 2011: ZCTA
delineation
• April 2011: ZCTA TIGER/Line Shapefiles
Urban/ Rural (Urban Areas)
• Two types of urban areas:
– Urbanized areas of 50,000 or more people
– Urban clusters of at least 2,500 and less than 50,000
people
• Rural areas
– Territory outside urban areas
• Census Bureau has classified Urban since 1906
• Urbanized Areas defined since 1950 Census
• Urban Clusters defined first for Census 2000

Urban Areas: Schedule
• November 22, 2010: Public comment period ends for
proposed criteria published in Federal Register
– http://www.census.gov/geo/www/ua/urbanruralclass.html
• First quarter of 2011: Final criteria published in Federal
Register
• March-December 2011: Delineation
• Spring 2012: Federal Register notice listing Urban Areas
• Spring 2012: Urban/Rural TIGER/Line Shapefiles
Traffic Analysis Zones: Background
• Sponsors
– American Association of State Highway and
Transportation Officials (AASHTO)
– Federal Highway Administration (FHWA)
• Census Transportation Planning Products (CTPP)
– Largest special tabulation done by the Census Bureau
• Primary participants
– Metropolitan Planning Organizations (MPOs)
– State Departments of Transportation (SDOTs)
Traffic Analysis Zones
Two types of areas:
• Traffic Analysis Zones (TAZs)
– Defined based on 2010 census blocks
• Traffic Analysis Districts (TADs)
– New for 2010
– Aggregations of TAZs
Traffic Analysis Zones: Schedule
• March/early April 2011: Mail out of materials to
MPOs and State DOTs
– Participants have 3 months to delineate TAZs
• June 2011: Return deadline for submissions
• October 2012: TIGER/Line Shapefiles include
2010 TAZs
PUMA Types
• Standard PUMAs (one level)
• Place-of-work (POW) PUMAs and migration (MIG) PUMAs are
proposed to be county based, consisting of:
–
–
a single PUMA for county-based PUMAs
a combination of adjacent tract based-PUMAs, so that together the
PUMAs compose one or more complete counties

Population Threshold for PUMAs
• Each PUMA must have a minimum 2010 Census
population of 100,000
• Minimum population must be met at the time of
delineation and maintained throughout the decade
• Number of PUMAs should be maximized
– PUMAs should not contain more than 200,000
people
PUMA Guidelines
•
Federal American Indian reservation/off-reservation
trust land (AIR/ORTL) relationship wherever possible
•
Wherever possible, each PUMA should comprise an
area that is either entirely inside or entirely outside a
current Core Based Statistical Area
•
Use place definitions, urban/rural definitions, as well
as local knowledge to inform PUMA delineation
PUMA Draft Schedule
• November 2010: Proposed criteria will be
distributed to SDCs and a wide variety of
stakeholder groups
• August 2011: Materials sent to SDCs for
PUMA delineation
• Fall 2011: Hands on training using MTPS
• January 3, 2012: Return deadline for
submissions
