00c School District Sources and Uses of Funds .. goto topics

Survey Forms

2023 General Survey

2024 General Survey

About the Data -- the 2023 Survey of School System Finances, similar to previous Census Bureau/National Center for Education Statistics programs, covers the entire range of government finance activities - revenue, expenditure, debt, and assets (cash and security holdings).

The program consists of 14,733 public school systems as counted for the 2022-23 survey cycle in a May 2024 listing of school systems in the Governments Master Address File. This includes approximately 13,500 school districts.

Charter schools whose charters are held by operators that are not governmental are considered to be out of scope for the purposes of Census Bureau government finance statistics. In these cases, school district payments to charter schools are included (within the expenditures of the paying school district), but the finances of the charter schools themselves are excluded from the statistics (and thus are excluded from the summary tables and data files).

With the exception of school systems in Alabama, the District of Columbia, Nebraska, Texas, and Washington, the 2023 fiscal year for school systems in all states began on July 1, 2022 and ended on June 30, 2023. The fiscal year for school systems in Alabama and the District of Columbia ran from October 1, 2022, through September 30, 2023. The fiscal year for school systems in Nebraska, Texas, and Washington ran from September 1, 2022, through August 31, 2023. Survey data are not adjusted to conform school systems to a uniform fiscal year.

School District Sources and Uses of Funds -- Start-up View
This graphic shows the 2023 sources and uses of funds profile for Los Angeles Unified School District. By dbl-clicking the school district name in the left column, a profile of sources and uses of funds is displayed on the left, in the grid.


Complete Excel profiles
Examples of school district sources and uses of funds profiles are shown below. Each is similar and organized in six sections: location and number of students, per pupil, total revenue, total expenditures, capital layout and selected groups of expenditures and revenue. The per pupil section enables comparison of one district to another. The field name column shows the field name in the dataset.
  - Alexandria City Public Schools VA -- District of Columbia Public Schools
  - Laguna Beach School District CA -- Irvine Unified School District CA
  - Los Angeles Unified Schools
  - Murfreesboro, TN Public Schools -- Rutherford County Public Schools
  - Hawaii Public Schools
  - Wichita, KS Public Schools
  - Winfield, KS Public Schools -- Arkansas City, KS Public Schools
  - Houston ISD, TX - Dallas, ISD, TX

Integrating the Data in Usage with VDAGIS


California
Los Angeles Unified enrollment has decreased by nearly half in the past two decades, from 747,009 in 2003-04 to 387,152 in the current year. Note the data for the 2023 year show enrollment of 427,795. Since 2016-17, L.A. Unified enrollment has dropped nearly 30%. Over that same period, the state decline was just under 7%. See more about this story in the LA Times article.

Discussion topics
  • the opportunity to use a standardized (across states) format for comparison.
  • why most school administrators are unfamiliar with these data.
  • the application uses cash-based, fiscal-year accounting, different from accrual or calendar year methods.
  • charter schools -- excluded unless part of a district and not listed by name.
  • age of data; FY 2023 most recent available.
  • data focused solely on funding; how to pair it with ACS and CCD Nonfiscal data for a full profile.
  • guide for setting voucher amounts; but private schools omitted.
  • identifying other valuable insights and practical use cases.

A look ahead
  • again covered next week; expanded to side-by-side comparision of distticts.
  • addition of per student and related measures.
  • different formats; vertical displays over a set of districts for selected items.
  • VDAGIS mapping school district sources & uses of funds projects.
  • development of Web page similar to 2022 data including interactive table.

3. About Congressional Communities & Congressional Districts .. goto topics

Congressional Communities (CCs) are geographic areas that subdivide Congressional Districts based on census blocks. CCs in a CD uniquely exactly exhaust the area of the corresponding CD. CCs provide a way to examine regional differences across each CD. New 119th CCs have been developed based on the 119th Congressional Districts. CCs typical range from 30,000 to 70,000 in population. CCs provide a way for stakeholders to make their voice better heard on legislative policy and agency rule-making issues that affect residents that affect commeunity needs. Participate in your Congressional Community (CC), a subdivision of a Congressional District.

.. what this does; user benefits
    - a batch application embedded in VDAGIS tools
    - main benefit is generated site demographics for circle(s) defined by the user
    - enables a series of site analysis applications based on a set uf user supplied site attributes
    - example: user enters a site attribute string like "1,39.354,-120.18,1"
        these can be keyed into the listbox or pasted from a text file
    - 4 items in a comma-delimited string
        site ID
        latitude of center point for site
        longitude of center point for site
        radius of site circle for site, floating point miles
    - each row in the listbox is processed as a site
    - results are written back in the listbox and can be saved as a file upon processing completion

.. start the Site Analysis API from the VDAD main menu: Analytics>Site Analysis API

.. processing works on the "active layer" in the GIS project -- selected by the user
    - when a layer name is clicked in legend panel, it is the active layer
    - all items in this layer are then shown in checked listbox shown at right in user interface
    - user can select one, many or all items
    - clicking the Run button starts the process
        shapes in the active layer that intersect with the circle are summed
    - at end of processing the message "done" is shown

.. an example using the Tahoe National Forest, CA (TNF) GIS project
.. note in this example, the site profile only includes only TOTPOPA23
    - total population based on ACS23 estimate
