School district estimates posted on this site were revised May 16, 2003, to reflect corrected geographic boundaries for school districts in the following 14 states: Iowa, Kansas, Massachusetts, Minnesota, Missouri, Montana, Nebraska, New Hampshire, New Jersey, Oklahoma, Oregon, South Dakota, Texas, and Vermont. Only these states were affected by the revision; the date stamp in the FTP directory, and the date tag within the data files, identify the updated files. This link provides the list of school districts with a population or poverty estimate change.
Additionally, files for three states were updated for corrections to the following district name or ID number : North Carolina (37 37099 Eastern Cherokee Reservation Schools), Pennsylvania (42 15150 Meyersdale Area School District), and Virginia (51 04020 Williamsburg-James City County Public Schools). The population and poverty estimates remain unchanged.
School district population and poverty estimates for income year 1999 were initially released on this site in December, 2002. The school-age population figures in all files were replaced on February 27, 2003. The initial release contained only school-age children in families, instead of all school-age children. On average, the revised counts are larger than those they replace by 3 percent. The February 27, 2003 revision did not affect either the total population or the estimated number of poor school-age children related to the householder.
I. File Organization:
The files in the FTP directory contain estimates of population and
poverty. The school districts for which we have estimates were
identified in the 2001 school district mapping project's survey
which asked for all school districts as of July 15, 2001. Thus the 1999
estimates reflect poverty in 1999 of the population in 2000 for school
district boundaries in the 2001-2002 school year. There is one
file for each of the states, the District of Columbia, and the entire
United States. Each file contains the FIPS state code, Department of
Education Common Core of Data (CCD) ID numbers, District names,
the total population, population of school-age children, and estimated
number of poor school-age children related to the head of the household.
II. File Names
Two kinds of files are located here:
