Presentation Overview
  • Boundary and Annexation Survey (BAS)
  • - What is the BAS?
  • - Why do we conduct the BAS?
  • - What are the current and future BAS submission
    methods?
  • - What are important dates for the current BAS
    year?
  • - Who should you contact if you have questions?

3
What is the Boundary and Annexation Survey (BAS)?
4
Boundary and Annexation Survey (BAS)
  • Voluntary survey conducted annually to collect
    boundaries for legal areas
  • Primary source of information regarding
  • legal boundaries
  • names of governments
  • legal status
  • types of governmental units
  • new governments
  • boundary changes
  • geographic relationships
  • e.g. a place annexes into a new county or minor
    civil division (MCD)

5
Boundary and Annexation Survey (BAS)
  • Governmental units (entities) included in the
    survey
  • counties and their equivalents
  • MCDs
  • incorporated places
  • American Indian reservations and off-reservation
    trust lands (federally recognized)

6
Why do we conduct the Boundary and Annexation
Survey (BAS)?
7
Boundary and Annexation Survey (BAS)
  • Ensures that population and housing counts are
    assigned to the correct geography
  • Used to present statistics for various censuses
    and surveys
  • American Community Survey (ACS)
  • Population Estimates Program
  • 2010 Decennial Census Programs

8
Legal Boundary Changes versus Boundary
Corrections
The two types of modifications that can be made
to a boundary are legal boundary changes and
boundary corrections. A boundary change is an
alteration to a boundary as a result of a legal
action (i.e., ordinance). Reporting legal
boundary changes is the primary goal of the BAS.
A boundary correction is the adjustment of a
boundary to correct an error in how the Census
Bureau depicts an existing boundary and does not
require legal documentation.

Preparing for the Boundary and Annexation Survey
(BAS)
10
Determining the BAS Contact
  • Each year BAS materials are mailed to our BAS
    contacts
  • How do we determine who the BAS contact is?
  • We are instructed by a local official as to who
    should receive the BAS package
  • A local government employee responds to the BAS
    multiple consecutive years, the Legal Areas team
    will make them the BAS contact.
  • If we have not received a BAS response for
    several years, the Legal Areas team will attempt
    to establish a contact in either a planning or
    GIS department.
  • The Advance Response phase (non-decennial phase)
    of BAS provides contact updates
  • State Data Center staff provide contact updates
    to the Census Bureau during the telephone
    follow-up phase of BAS.
  • If there is no BAS contact and the Census Bureau
    is unable to establish a contact, the package
    will be mailed to the Highest Elected Official
    (HEO)

11
Advance Response (non-decennial years)
  • Sent in September-October
  • Participants receive a letter, one-page form, and
    one-page informational insert about the BAS via
  • Mail
  • E-mail
  • Fax
  • Requests participants to
  • Verify contact information
  • Indicate if they have boundary updates to report
  • Indicate the method they would like to submit
    their boundary updates

12
Submission Methods
  • Paper Submission
  • Web-BAS
  • MAF/TIGER Partnership Software
  • Digital BAS

13
Paper Submission
  • Census Bureau
  • mails paper maps and a BAS form to the BAS
    contact
  • Participants
  • annotate and return large scale paper maps and
    forms
  • provide documentation for each legal boundary
    change (date, number, acreage)
  • If the participant does not have any changes to
    report, they can return a No Change postcard

14
WEB-BAS
  • Participants
  • Currently (E-BAS)
  • are able to
  • login to a secure website
  • submit a No Change postcard or form updates.
  • are not able to
  • submit map updates
  • In 2009 (Web-BAS)
  • are able to
  • submit spatial data
  • The E-BAS website is linked off of the BAS
    homepage (http//www.census.gov/geo/www/bas/bashom
    e.html) and the username and password are
    provided in the Special Instructions section on
    the paper form.

15
MAF/TIGER Partnership Software
  • Available for 2008 BAS
  • Participants will receive
  • a CD containing the software to install on to
    their computer
  • one or more CD(s) containing the data for their
    entity and the surrounding area
  • a user name and password to access the data in
    the software
  • Participants will be able to submit map and form
    updates.

16
Digital BAS
  • First offered during the 2005 BAS for a limited
    number of entities
  • Designed to accept submissions from experienced
    users of Geographic Information Systems (GIS) who
    modify Census Bureau spatial data
  • Spatial data provided in GIS shapefile format
  • Goal is to permit governmental units to
  • update digital files in place of paper maps
  • submit boundary change information through
    digital file metadata
  • Participants are required to
  • follow the detailed requirements posted on the
    BAS website http//www.census.gov/geo/www/bas/ba
    shome.html
  • Limited to entities and counties
  • that have gone through the Census Bureaus
    MAF-TIGER Accuracy Improvement Project (MTAIP)
    process

Future Goals
  • Boundary Validation Program (BVP)

    Boundary Validation Map to the Highest Elected
    Official of every legal entity in the United
    States for final review before tabulation.
