The update showed LISD has declined by 583 students in the last five years and will continue to decline by approximately 500 students in the next school year.
Templeton Demographics Representative Rocky Gardiner said Texas as a whole has seen a "tremendous slow down in enrollment."
In the 2018-19 school year, Texas had an enrollment growth of about 32,000 students, which Gardiner said has been as high as 80,000 students in previous years.
Gardiner said charter schools received 20,000 of that enrollment growth and public schools around 12,000.
Part of LISD's decline is due to charter school growth, but also because exiting senior classes have been significantly higher than the incoming kindergarten classes, according to Gardiner.
However, Gardiner said he does anticipate the district having a fairly large kindergarten class next year.
"We expect the kindergarten class will be up by 100 students, where last year it declined by 40 [students]," he said.
