  Analysis/Interpretation: Data Usage

Using GIS to Assess Long-term Demographic Change

The change in population density by county for a 10-state great plains regions is chronicled by a set of Web pages starting with the 1940 10-state region by county population density map. Maps of this type can be an effective tool to make compelling presentations either in the form of Web pages or slide shows.

Geographic Reference Files and Software

Proximity has developed Address Matching Street Shapefiles and Address Match/Code software for use to (1) depict streets in mapping and GIS applications and (2) address-match and geocode user supplied site/address-oriented data and linkage to Census 2000 demographics.

  Funding and Resource Allocation Applications

This section reviews applications that involve use of Census 2000 data in funding and related resource applications.

Using Census 2000 Data for ESEA Title I LEA Funding Allocations

The Elementary and Secondary Education Act (ESEA) is operated by the U.S. Department of Education and distributes in excess of $8 billion annually to local education agencies (LEAs). The ESEA Title I program is designed to improve educational opportunities for low-achieving children in schools and school districts (LEAs) serving areas with high poverty.

The allocation of funds to LEAs is based on a complex formula that involves use of decennial census and other data. Under reauthorization legislation recently enacted, and under similar measures expected to be before Congress in the fall of 2002, the formulas make use of 1990 Census-based estimates.

Proximity has compared the 1990 Census-based estimates with corresponding Census 2000 data for school districts and found large differences between the population estimates and the Census 2000 data. The magnitude and direction (overestimate or underestimate) of the differences vary widely for LEAs. Although an assessment is yet to be performed, the differences in magnitude of the estimates suggest the substantial possibility of within-state LEA funding allocation inequities, thus prospectively undermining the a primary goal of the ESEA Title I program (some LEAs possibly getting more funds than they should, others receiving less than they should - per the intent of the legislation). See for more information.

The ESEA Title I formula, among other criteria, makes use of data on the number of persons 5-to-17 years of age for each school district. These data are available in the Proximity Census 2000 school district demographics database. See sample application. Data on the number persons 5-to-17 years of age play a role in other Federal funding and resource allocation programs that will be reviewed in this section in the future.

  Mapping and Geographic Information System Applications

This section reviews mapping related applications/resources and topics that are a merger of the access and analysis sections. Mapping and GIS applications are important and widely used with decennial data and warrant this special focus. In addition, the Census Bureau TIGER/Line files from the foundation for many mapping and GIS resources and are thus also connected for this reason.
