- 23. Viewing and Downloading BAS Maps http://www.census.gov/geo/www/bas/bashome.html

- 29. Important Dates and Deadlines Date(s) Description December Advance Response Letters and Forms mailed to the BAS Contacts December -February BAS Materials mailed to the BAS Contacts January 1 Boundary Changes (annexations and detachments) reported to the current BAS must be in effect on or before this date. February 1 Last day for participants to request BAS materials to be shipped by mail. March 1 First Deadline: Changes received by this date will be included in the upcoming Population Estimates Program and ACS. Boundary updates will be depicted on the next release of BAS maps. May 31 Final Deadline: Changes received by this date will be depicted on the next release of BAS maps
Editor's Notes
- Circular No. A-16 designates layers of geographic information and what agencies are responsible for maintaining them. For example, geo.data.gov and the National Map are both maintained by USGS, but the Census Bureau supplies the boundaries and the street features.
- This survey replaced the long form. **If the audience asks about the ACS ACS is conducted monthly and reported annually. 3 types of ACS estimates: 1-year estimates: produced annually for geographic areas with pop > 65,000 3-year estimates: produced annually for geographic areas with pop > 20,000 5-year estimates: for small areas. In 2010, Census plans to release the 1 st 5-year estimates for small areas, based on ACS data collected from 2005-2009. 5-year estimates released in 2010 use older geography (ex: 2000 census tracts, but 2009 legal boundaries, etc.) and provide a picture of the country for that 5 year period. By contrast, the data reported from the 2010 Decennial Census uses 2010 geography and provides a picture of the country in 2010.
- This program and ACS (previous slide) are available through American Fact Finder.
- All groups benefit from more accurate assignment to geographic areas Federal funding is determined by the findings of the BAS In some states, state funding too
- All groups benefit from more accurate assignment to geographic areas Apportionment of Federal funds In some states the apportionment of state funds are affected Community planning
- For Georgia and Michigan, the state government will send the list of entities with boundary changes and/or legal updates directly to the Census. The Census then uses this list to determine which entities will receive a BAS package. For all other states, the entities provide the updates directly to the Census. Please note that we donāt eliminate contact with the local governments. Once a year, they still receive a letter from us, even if they are in a state agreement.
- There are currently more than 40 county-level BAS agreements. These help us reduce duplication, save on packaging costs, and are also more environmentally friendly If you are interested in a county-level agreement please contact the Legal Areas Team
- Reasons itās good to have a good BAS contact: Itās important to get it to the right people It saves money It makes a more effective BAS We used to have a terrible package return rate; now we spend a lot of time keeping contacts up-to-date, which has improved the return rate immensely.
- We will not be shipping paper maps to anyone, unless they request one.
- If the contact information is the same as the BAS Mailing contact simply check this box (point out box) If the contact information is the same as the HEO check this box (point out box) We also need to know who made the updates.
- If we are missing anything, this is the respondentās chance to correct it.
- Five steps to update BAS: 1. annotate legal boundary changes and/or corrections on the map 2. compare the address breaks at the intersection of any road and boundary to a local source 3. complete the form 4. print and sign your name, and enter the date in the āSignature Boxā on each map that has changes return the signed maps and survey forms Boundary changes are drawn by the participants relative to the features present on the map. This may cause spatial inaccuracies but ensure correct topological location. Legal Disputes If it comes to our attention that an area of land is in dispute between two or more jurisdictions, we will not make boundary corrections or add annexations until the parties come to written agreement, or there is a documented final court decision regarding the matter/dispute.
- Digital BAS is for participants who do not want to update paper maps, and who are experienced with using GIS.
- MTPS is a customized GIS system for developed by the Census Bureau for participants who do not have their own GIS or are not experienced GIS users.
- Maps can be viewed and downloaded directly from the BAS website. Remember that you wonāt receive a paper map unless you request one.
- Re-emphasize contacts sheet
