  • After the 2010 Census, the Census Bureau Director and his staff as well as all 12 regional directors worked together to build the restructuring plan. Our regional office structure has remained substantially unchanged for 50 years. Over 20 regional office designs were considered, ranging from 4 to 12 regions.
  • Regional Offices are located in the following cities:New York, NYPhiladelphia, PAAtlanta, GAChicago, ILDenver, COLos Angeles, CAThere are a total of 6 geographers working for the Atlanta Regional Office – four of them work in the office located in Atlanta and two of us work from our homes. David Cline works from his home in Harrisburg NC and I work from my home in Charlotte. My primary partnership activities is working with governments in South Carolina. David Cline is my back-up.
  • We want to begin today’s presentation with some background on other initiatives from past decades.For 1990 Census - Census Bureau developed TIGER (Topologically Integrated Geographic Encoding and Referencing System) Census partnered with USGS to help build TIGER in rural areas; Census partnered with local governments in urban and suburban areas ( included 1980 GBF DIME File areas) Majority of maps received from GUs were paper maps that had to be digitized – 10 stations, 3 shifts1st time Census had spatial data for the nation, Puerto Rico and US Island Areas Originally planned as a 20 year resourceFor the 2000 Census – Bureau created MAF (Master Address File)Before MAF, Census compiled list of addresses from scratch, took significant effort to build address file each decade MAF compiled from:Decennial and survey field operationsHistoric agreement: USPS provides DSF (Delivery Sequence File) to Census twice a year LUCA (Local Update of Census Addresses) Program legally mandated– 1st time local GUs given the opportunity to review Census Bureau’s list of individual addresses; stipulations- sign confidentiality agreement, use information for Census purposes only, information destroyed/returned at endMAF used to support decennial census and also feeds into survey samples for monthly surveys including ACS MAF contains records for HUs, GQs, Transitory locations and non-residential addressesFor 2010 - Census conducted the MAF/TIGER Enhancement Program (MTEP)MTEP integrated MAF and TIGER into MTDB (MAF/TIGER Database) on Oracle spatial platformSpatially corrected street featuresCollected address point data (field staff captured lat/long at entrance to living quarters)Size of combined MAF/TIGER database: 28-30 terrabytesFor 2020, Census begins the GSS Initiative Program to build upon all of the prior initiatives
  • So, what is the GSS-I?In a nutshell, its’ an integrated program consisting of:Improved address coverageOngoing address and spatial database updates (annually instead of once a decade)Enhanced quality assessment and measurementBuilds on our relationship with partners and recommendation of stakeholder and oversight communitiesMost importantly, it supports a targeted Address Canvassing in preparation for the 2020 CensusMore about this idea and why this is important is outlined on the next few slides
  • This slide is intended to set the stage for introducing the GSS-I by presenting a high-level view of “the way it was done in the past.” Address list development for the 2010 Census (and to some degree the 2000 Census) was accomplished by relying on:USPS Delivery Sequence File Updates twice a yearThen we had once-per-decade partnership programs like LUCA and New ConstructionA massive field operation in 2009 called Address Canvassing covering the whole nation, requiring a lot of resources (people, time, equipment and MONEY).
  • In 2009 the Census conducted a complete Address Canvassing Operation. Over 140,000 temporary census workers were hired to verify 145 million housing unit addresses. They used hand-held computers to update feature and address information and capture lat/long coordinates for all living quarters. It took 151 local census offices to manage the operation that began March 30 and ended mid-July 2009.Just over 100 days to complete the massive operation!Duringand after the 2010 Census, we held many formal and informal meetings with our stakeholders and oversight communities. And, we listened to what they said and what we heard over and over again were:We need to develop ongoing partnerships, not just once in a decade with local governments. Local governments, in most cases, have the most complete and most accurate address and centerline information. We do not need to duplicate these efforts when we know that this quality information is readily available at the local level.We have to do a better 2020 Census with less resources – aka – Money
  • We have a shift in focus for the 2020 : instead of a complete Address Canvassing we do a targeted address canvassing. It hinges on having an acceptable address list for each level of government.Note that what defines “acceptable” will be a partnership collaboration between government partners and the Census BureauFor 2010, our partners (mayors, chairmen of county commissioners, etc.) took comfort when they understood that during Address Canvassing, Census staff would be visiting every street in America to make sure our address list was comprehensive.
  • If we implement programs designed to more regularly update the MTDB using sources other than the USPS, *AND*Develop methodologies to assess the quality and currency of the address list and spatial data, we should be able to identify areas where we are confident enough in our data that we DON’T HAVE TO CANVASS. Hence, “targeted.”As a result we “target” only areas with uncertainty.
  • To Reiterate.. The goal of the GSS-I is improvement in four arenas: address, feature, quality and partnershipLet look at these in more detail.For address improvement we want to:1.Initiate programs with partners to continually receive addresses throughout the decade2.Explore ways to achieve complete address coverage and a current address list3.Includefocus on rural addresses, Puerto Rico and group quarters, areas traditionally not covered as thoroughly in the USPS’s Delivery Sequence File4. Evaluate commercial address list sourcesFor feature improvement we want:1. A continuous update of the street network and attributes to facilitate improving the assignment of addresses to their correct geography (Geocoding)2. To broaden participation and submission options in existing programs (i.e. BAS)3. To develop new partnership programs to facilitate exchange of spatial data throughout the decade4. To research change detection methodsFor Quality improvement we want to:1. Thoroughly evaluate the content of the MTDB: the inputs, our update processes, and the outputs (products)2.Research effective methods for evaluating existing data, including the use of local data as a benchmark for comparisonAs far as Improved Partnerships we want to:1. Research methodologies and develop pilot programs for working with partners in acquiring address and spatial data in the most efficient and least intrusive ways
  • ACS and other surveys use the MTDB to create their sample frames; better data in = better demographic data outOur hope is that continual updates will reduce the burden required to participate in LUCA (if our address list is more current, that’s less work for you at the end of the decade).It will result in taxpayer savings: By establishing these partnerships, and developing the means to continually update the Census Bureau’s address and spatial data, we avoid the necessity of having address canvassers walk every street in the U.S. looking for updates prior to the 2020 Decennial Census.Every year the Federal Government distributes more than $400 Billion based on Census Counts – an accurate count is key! It’s been estimated that an entity loses funding in the amount of $1200/per person/year for anyone not counted in the Census. Now multiply that amount by 10 years! WHAT TYPE OF FEEDBACK WOULD PARTNERS LIKE TO RECEIVE? WHAT WOULD BE HELPFUL? Bearing in mind that individual addresses and address points are covered by Title 13 Confidentiality requirements.
  • Here’s a graphic depiction of the GSS-I Quality Assurance goals for the MTDB and processes:We want to:develop metrics and quality indicators in order to assess the quality of the data we already have in the MTDB evaluate the quality of incoming data evaluate the ways we process the data into the MTDB evaluate the data in our products
  • Local governments are the authoritative sources for address and spatial data. You know your area better than anyone else. We want to work with you to acquire your address and spatial data in the most efficient and least intrusive way.
  • Address number, complete street name (directional, proper name, and street type); for multi-unit structures, within structure identifier including a descriptor and unit identifier (all different examples - Apt 1, Lot 22, Garage Apt), ZIP code.

  • SouthCarolina was involved in some pilot work last year. Final recommendations from these pilots are under review and will be available soon. Currently six South Carolina counties are participating in a test to evaluate our processing and control systems for the GSS-I. These include Aiken, Dorchester, Greenville, Newberry, Spartanburg and York counties. Lots of ideas working their way towards implementation. Expect several different modes for data transfer, as well as some new online tools for address/spatial data management and/or standardization. Ideally, these tools will allow locals to better manage their own data, in addition to providing it to the Census Bureau.We WILL have a means for partners to ftp files to us using the web.Also, we will be requesting metadata on the files (at least to some degree), so that we aren’t guessing at what the data means…ENHANCED PARTNERSHIP TOOLS: Continued evolution of the MAF/TIGER Partnership Software, WebTIGER,
  • This is a graphic that providesa summary of the GSS initiative along with the key components. Beginning at the top, the Census Bureau starts with the existing MAF/TIGER database and works with partners to obtain updated address and spatial data. Quality assurance occurs throughout the lifecycle of the initiative. The end result is agreement from partners for a targeted address canvassing.
  • Lot of information and data is available for download.Go to the Census website www.census.gov. In the middle you will see a tab for Geography. Click on it. You’ll see several options. Click on Maps and Data if you are interested in downloading shapefiles. Go to Partnerships to find out more information on programs like the Boundary and Annexation Survey (BAS). On the left hand side of Geography menu you’ll see button for the GSS Initiative.
  • If you are interested in the Census Bureau making a presentation or conducting a workshop on census data, census geography, for example using the American Fact Finder to create maps in Arc Map, please contact the Geography Section at the Atlanta Regional Office. The number is 404-331-1339. Or email David and/or me. We’ll forward your request.The Census Bureau conducts webinars, too. There was one last week by the Boundary and Annexation folks. They covered how to submit a digital BAS, paper maps, and using the Census Bureau Maf Tiger Partnership Software.David and I want to thank the SCARC for allowing us to participate in this year’s conference and to thank you for attending our session.

  • 2010 Address Canvassing Facts• Number of housing unit addresses that neededverification: 145 million• Number of census workers hired for AddressCanvassing: 140,000• Number of hand-held computers used: 151,000• Number of local census offices that managedoperations: 151• Dates of operation: March 30 - Mid-July 2009
  • A Shift in Focus for the 2020Census• From a complete Address Canvassing toa targeted Address Canvassing– Hinges on establishing an acceptable address list foreach level of government8
  • Why a “Targeted” AddressCanvassing?• $$$! It is VERY expensive– Field an ARMY of address canvassers– “Walk” EVERY street in the nation…• Goal: developing regular update and changedetection processes• Result: “Target” only areas with uncertainty– Quality of Addresses– Currency of Addresses
  • Address improvement: explore methodologies toachieve complete coverage and a current address listFeature improvement: ongoing update of the streetnetwork and attributes to improve the matching ofaddresses to their correct geographyQuality improvement: broaden quality assessmentsand provide quantitative measuresImproved Partnerships: strengthen existing anddevelop new partnershipshttp://www.census.gov/geo/www/gss/Goals of the GSS Initiative

  • Partnerships are Key!• Local governments are the authoritative sources foraddress and spatial data!• Expanding our Partnerships is Critical– Key step towards establishing an accurate and up-to-date address list• The GSS-I Partnership Program seeks government,organizational, and commercial partners willing to sharehigh-quality data on:– Addresses– Housing Unit Structures– Street Centerlines and Attributes
  • What Kind of Address Data?• City-style addressesand/or• Non city-style addresses (i.e., Rural Route #)that “ideally” meet:1. USPS minimum delivery requirements, and2. The FGDC Address Standard (U.S. Thoroughfare, Landmark, and PostalAddress Data Standard)See the Draft Census Bureau Address Data ContentGuidelines:http://www.census.gov/geo/www/gss/gdlns/addgdln.html
  • What Kind of Housing Unit Structure Data?• Latitude/Longitude Coordinates for a Housing Unit structureor access point (i.e., from E-911 or Next-Gen E-911database)• Structure centroids• Latitude/Longitude Coordinates for a real property parcel orparcel centroid• Other points used by partner?Again, see the Draft Census Bureau Address Data ContentGuidelines:http://www.census.gov/geo/www/gss/gdlns/addgdln.html
  • What Kind of Street Feature Data?• Street centerline geometry• Street attributes – names, address ranges, etc.In order to:• Expand Census centerline and attribute coverage• Spatially-correct misaligned streets in conjunction withhigh-quality imagerySee also the Census Bureau Draft Feature Data and MetadataContent Guidelines:http://www.census.gov/geo/www/gss/gdlns/addgdln.html
