For the approximate largest 3,300 school districts with population 20,000 and over, wide-ranging demographic updates are available (as of 12/8/08) from the 2005-07 "3-Year" Census Bureau American Community Survey (ACS). A main importance of these data is that they are the first set of wide-ranging demographic data available for school districts (with exception of school districts coterminous with county boundaries and having population of 60,000 or more) since Census 2000. They enable assessment of more recent characteristics than provided by Census 2000. They enable assessment of how some demographic measures have changed since 2000. There are a few new types of measures that can provide different insights.
Availability and Reliability
The population of threshold of 20,000 is not arbitrary. Reliable estimates for smaller population areas cannot be developed from the ACS survey design. More attention to reliability of estimates is required as compared to sample based estimates from the decennial census. Some relative sense of the Margin of Error should be kept in mind while using these data.
Data Access and Analysis
While these data are readily accessible using the Census Bureau http://factfinder.census.gov, they are quite difficult to use in an analytical manner. For example, there is no facility to "browse across" or sort school districts using a dataset/extract of these data. There is no facility to view these data as thematic maps to visually examine patterns. There is no facility to integrate other related data. This section reviews Proximity software and integrated data focused on accessing, viewing and analyzing these data. Applications shown here focused on Texas can be produced for any region using the same toolset.

SDProfile Software, Database & Analytical Profiles
Use the SDProfile software and SDProfile database to explore and compare updated demographics for selected districts. Compare these 2005-07 estimates with corresponding Census 2000 data (see earlier section tables). Klein ISD, for example, has increased in total population from 141,414 to 192,100. How has the total resident population ages 5-17 years changed? How has the K-12 enrollment participation rate changed over the period? How does this district compare to peer districts?
The following view shows side-by-side demographic profiles for three districts. Table 00-1 shows the Census 2000 population by age. Table 07-1 shows the ACS 05-07 population by age.
Use the Select table to view feature, as illustrated below, to view a specific table of interest (select from tables listed above). In this example, the 05-07 ACS estimates for school enrollment and educational attainment are shown.
The spreadsheet displayed above may be exported to Excel or CSV
Unlike the complete count tabulations in the decennial census, all ACS data are survey-based estimates and have an error of estimation and associated margin of error (MOE). By adding and subtracting the margin of error from the point estimate, you produce the range around it called the confidence interval. With 90 percent confidence, the interval 15,120 +/- 1,377 (the MOE for this estimate) contains the true Klein ISD population estimate for the population 5 to 9 years of age. This information means that if the survey is conducted 100 times, the number of respondents in this age group would range between 15,120-1,377 and 15,120+1,377 most (90 percent) of the time.
Estimates of size 100 or smaller may have a margin of error larger than the estimate. An estimate of 10,000 may have a MOE of 1,000-1,200; an estimate of 20,000 may have a MOE of 1,400-1,600. Precisely computed MOE values are available for all ACS estimates.
The SDProfiles Browser feature enables paring through a spreadsheet structure where a row contains attributes of a school district. Once the spreadsheet is loaded, the selection of districts can be sorted on an item of interest and columns summed. Invoke the Tools>Browse feature.
The Browse form appears.
Click the Load button to populate the grid with the file <sdacs071.dbf> and include only those records that match the criteria <state='06' .and. sduni<>' '>.
Click the Sum button to sum fields as shown below. the TOTPOP field/column has been resized with mouse to view larger field sum value 24,832,378, the sum of the total population of all California unified school districts.
Change the query/filter and click Load to examine a different set of districts:

The map is displayed in the currently open browser window. Two successive map views will therefore use the same browser window. If you do not want the current browser window to be used, open another browser window and make it active. The map will be displayed in that window. Use this method to display two school districts of interest or a school district and related metro. Only MSA maps are shown. MISA maps are not supported with this version. |
