Lineage The original 1990 School District file delineation work was done at LMIC on contract to the U.S. Census Bureau. The Census Bureau was under contract to the U.S. Department of Education to create a nationwide school district file and population totals that matched the 1990 Census boundaries. LMIC provided delineations of the school district boundaries to the Census Bureau, based on map information provided by the County Assessors' Offices to LMIC. The Census Bureau did the automation of the 1990 file.

Subsequent annual updates have been made to the file, to reflect boundary changes, boundary corrections, and school district consolidations. In addition, school attendance area boundaries have been added to the most recent files. These updates have been done by the Minnesota Legislative GIS Office (LGO), the Land Management Information Center (LMIC), and the Office of the Secretary of State, with assistance from the Minnesota Department of Children, Families, and Learning.

The steps used to create the original 1990 file and subsequent updates to 1999, are outlined below.

CREATION OF THE ORIGINAL 1990 SCHOOL DISTRICT BOUNDARY FILE:.

1. Delineation of school district boundaries (LMIC):

LMIC's role was to delineate school district boundaries to match Census county, mcd, tract, and block boundaries. LMIC received a set of large-scale (approx 1:800) maps of census boundaries from the Census Department. These census boundary maps included mcd, tract, and block boundaries.

LMIC obtained school district boundary maps from the County Assessor's office in each county. LMIC sent blank County Highway Maps to each County Assessor, and received back those maps with the school districts delineated on them. The Assessor's Offices drew the boundaries according to their official records. LMIC still has these maps on file.

Using the County Assessors' delineation maps, LMIC transferred the school district boundaries onto the 1:800 Census maps. Census had very specific guidelines, which they enforced. Delineations were to match to within 1/16 of an inch - basically, a fine pencil-width.

2. Automation of School District Boundary Linework

The Census Bureau did the automation of the maps to create the digital file. This was done in two steps:

1. Wherever the linework matched the Census tract, block, mcd, etc., boundaries, exactly, the census units were assigned a school district code via a lookup table.
2. Where the school district boundaries did NOT follow the Census Boundaries, then the Census Bureau digitized the necessary linework. These base maps for automation eventually came back to the state, and are stored in the State Demographer's Office files at Minnesota Planning.

3. Population totals (LMIC):

Where the school district boundaries did not match the Census boundaries, LMIC also provided population figures to apportion the Census unit population into the school districts. Rather than apportioning population strictly on the basis of area, this was done through examination of other maps; sometimes, as in the metro area, by counting the houses on aerial photos. The demographic distribution by school district was important as a basis for funding.

4. File distribution (Census Bureau):

In 1992, the automated 1990 School District Boundary files were delivered by the Census Bureau to the Legislative GIS Office (LGO) in TIGER/line format. LGO extracted the data from the TIGER format and created an ARC coverage, which was then provided to LMIC and other agencies. LMIC did not receive the digital files back from the Census Bureau for any type of review or verification. Errors in the school district boundary file were reported to the Legislative GIS Office and the Secretary of State's Office. These errors were corrected on the final file. Many of the errors relate to the Census boundary alignment problem - i.e., school district boundary lines were moved to coincide with the appropriate Census boundary.


ANNUAL UPDATES AFTER 1990:

1. (1992-1996) The Legislative GIS Office (LGO) made updates to the file as needed, based on boundary changes, boundary corrections, and school district consolidations. Information on necessary updates was forwarded to LGO by the Secretary of State's Office or the Department of Education (now the Mn Department of Children, Families, and Learning). Most updates to the files involved school district consolidations. LGO did updates for the years 1992 through 1996.

2. (1997-1999) LMIC obtained School District 1996 boundary file from the Legislative GIS Office, and updated with coding changes and consolidation information for 1997, 1998, and 1999. As part of a project for the Minnesota Department of Children, Families, and Learning (CFL), LMIC also added school attendance area boundaries to the file. To create the school attendance area boundaries, LMIC plotted school district boundaries over a basemap containing roads, municipal boundaries, and other features, and asked all school districts to draw on the maps their school attendance area boundaries. LMIC then digitized the school attendance area boundaries into the school district file. The 1999 school district file contains all school attendance area boundaries; this information in previous years' school district files is only partial. The file created has as the smallest unit of area the elementary school boundary. All larger areas: Middle school and high school attendance area boundaries and the school district boundary - are aggregated from the elementary school boundary. The LMIC 1997, 1998, and 1999 school district boundary file data sets were provided to LGO for distribution.

Notes on boundary corrections: based on the CFL/LMIC distribution of the school district boundary maps, some (60+) school districts reported errors in the digital school district boundary file. These error reports were forwardrd to the Office of the Secretary of State. All of these corrections have not yet been made.

General note on updating: In general, the Secretary of State's Office and LGO wil be updating and correcting the school district boundary file. LMIC, working for CFL, will be updating school attendance area boundaries and identifying school locations.

NOTES ON MISMATCHES OF DATA:

1. The County Assessor's office is required to delineate school district boundaries by law, and maintains the official record for tax purposes. It must be noted that the school districts also have boundary maps, and that, while the two sets of map boundaries should match, they do not always do so. In cases where the school district and the county assessor records show different boundaries, this should be resolved locally. It becomes an issue for the maintainers of statewide files when updates are obtained from both sources.

2. Mismatches between the Census Boundary lines and the School District lines: although the school district boundary file generally matches Census lines, it does not always do so. Therefore, mismatches can be legitimate, based upon the original maps from the County Assessor's Offices, and can be verified against the maps on file at LMIC and the Demographer's Office.

Entity and Attribute Overview The file contains school district boundary and name. The school district is further subdivided into school attendance area boundaries. School district attendance area boundaries aggregate to the school district. The smallest unit is the elementary school boundary, which may be collapsed up into the middle school boundary and the high school boundary.
