DMINews -- June 2007
CommunityViewer and Census 2010 LUCA Program The Census Bureau Local Update of Census Addresses (LUCA) program is a decennial census geographic partnership program focused on updating geographic data. LUCA gets operationally underway this summer. It will help the Census Bureau use local knowledge in developing its Master Address File (MAF) for the 2010 Census. The LUCA program presents an important opportunity to cities and other governmental units to participate in the development of the most accurate census possible. By improving the accuracy of the census, localities improve their opportunity to receive their fair share of Federal and other governmental funding and services. In states where a congressional seat might be potentially added or lost, the more important the collective participation of local governments across the state. Tribal, state, and local governments can contribute to a more complete and accurate census for their community by reviewing and commenting on the list of housing unit and group quarters addresses that the Census Bureau will use to deliver questionnaires within their community. The Proximity CommunityViewer software (http://proximityone.com/cv.htm) and related data resources can help tribal, state, and local governments participating in the LUCA program maximize the comprehensiveness, quality, and usefulness of the LUCA-related data. The Proximity program provides a means for LUCA program participants to use the data that they help develop and establishes a structure and tools for accessing and analyzing Census 2010 data in a manner integrated with other data. See more detailed information about using CommunityViewer and the LUCA Program. PlaceRank -- Ranking Places based on Flexibly Defined Criteria and Weights Where are the "best places?" ... the answer to this question depends on the weights and ranking criteria used. PlaceRank, an integrated software and database tool, enables you to rank cities/places based on criteria that you choose and weights that you assign. The detailed PlaceRank database enables you to generate side-by-side demographic comparative analysis profiles for cities/places of interest to you. Although extensive data are available for analyzing city infrastructure, socioeconomic composition and trends, and geophysical characteristics, only the PlaceRank database pulls together essential subject matter items. Many of the multi-sourced data items are difficult to obtain and require conversion into a form useful for analysis. See more about PlaceRank here -- http://proximityone.com/placerank.htm Census Bureau Transforming TIGER/Line Geographic Base Beginning in the fall of 2007, the Census Bureau will begin releasing TIGER spatial data in shapefile format. In February 1989 the Census Bureau released the first TIGER/Line files. The prototype TIGER/Line file was based on the Columbia, MO GBF/DIME file which I developed. The TIGER/Line files provided the first seamless nationwide street centerline coverage of the United States. With the modernization of the Census Master Address File (MAF) and Topologically Integrated Geographic Encoding and Referencing (TIGER) system, Census announces that the last TIGER/Line files to be produced from the legacy database are the 2006 First and Second Edition TIGER/Line files that have released (December 2006 and March 2007). From the new MAF/TIGER System, the Census Bureau will make available shapefiles, TIGER/GML, TIGER spatial data over the web (WebTIGER) using XML (Extensible Markup Language)-based GML (Geographic Markup Language), and the Web Map Server (WMS). More detail will be covered in later editions of DMINews. The near term impact. A review of the proposed new MAF/TIGER shapefiles suggests little will be lost in the translation. However, there are transitional issues. With completion of the 2006 Second Edition TIGER/Line (TGR2006SE) files in March, there are now 1,871 counties and 78 Puerto Rico municipios that have realigned street feature coordinates resulting from the MAF/TIGER Accuracy Improvement Project. Of the 1,871 updated counties, 272 counties are new with the TGR2006SE files (others were released earlier). The TGR2006FE and TGR2006SE files reflect the latest available governmental unit boundaries (generally January 1, 2006 and updates the 2005 versions that reflect boundaries for governmental units as of January 1, 2005). Many other counties are yet to be completed under the MAF/TIGER Accuracy Improvement Project; many would have have been released as the TGR2007FE files in [presumably] December 2007. It now appears those county updates will be released in the new TIGER shapefile structure. However, that leaves several hundred counties for which there will be no MAF/TIGER improved either TIGER/Line or TIGER shapefiles for the onset of the Census 2010 LUCA program. Watch later editions of DMINews for updates. Metropolitan Population by State -- Ranking Table The percent population that is metropolitan varies widely by state. Two states are comprised of 100 percent metropolitan population - can you name them? Approximately one-third of the population is metropolitan in the two states with the lowest percent metropolitan population - can you name them? These data are based on the population in metropolitan statistical areas (MSAs) as of July 2006, and for MSAs defined as of May 2007. Nationally, 83.28 percent of the population is located in MSAs. See the MSA-to-State Ranking Table to view states of interest. The ranking table also shows the percent personal income in metropolitan areas by state. Generally, the proportion of state personal income in metropolitan areas is slightly higher than the percent state population in metropolitan areas. The ranking table shows this relationship as an index. 2006 State Population Estimates by Age-Race/Ethnicity-Gender -- School Age Population Ranking Table The new state by population age cohort ranking table (http://proximityone.com/st0006.htm) shows percent change in school age population, 2000 to 2006, by state based on the latest estimates released in May. To use the ranking table, click on a subject matter column of interest to view different state rankings. 26 states experienced a decrease in the population under 18 years of age between 2000 and 2006. However, only 12 states, predominantly in the northeast, experienced a decline in the 0-to-5 age group during the period. Corresponding July 1, 2006 county level age-race/ethnicity-gender population estimates will be available later this summer. National Per Student Public School Spending Approaches $9,000 The nation’s public school districts spent an average of $8,701 per student on elementary and secondary education in fiscal year 2005, up 5 percent from $8,287 the previous year, based on data reported by school districts to the Census Bureau sponsored by the U.S. Department of Education and released in May 2007. New York spent $14,119 per student, highest among states followed by New Jersey ($13,800), District of Columbia ($12,979), Vermont ($11,835) and Connecticut ($11,572). Seven of the top 10 with the highest per pupil expenditures were in the Northeast, several being the same states with declining school age population -- see above. Among states with the lowest expenditures per student are Utah ($5,257), Arizona ($6,261), Idaho ($6,283), Mississippi ($6,575) and Oklahoma ($6,613). All 10 of the states with the lowest spending per student were in the West or South. In all, public school system expenditures were $497 billion, up from $472.3 billion the previous year and with the largest portions being instruction ($258.4 billion) and support services ($146.1 billion). Revenues were $488.5 billion in 2005, up from $462.7 billion the previous year sourced from state governments (47%), local sources (43.9%) and the federal government (9.1%). The School District Financial Analyst (http://proximityone.com/sdf.htm) integrated software and database provides access to these revenue, expenditure, debt/asset data by detailed category for each school district in the U.S. |
