As times changed, the demographic of Lee's student body shifted. As of 2008, it was made up predominantly of Hispanic immigrants and sons and daughters of Hispanic immigrants. Lee's multi-ethnic population changes parallel Houston's immigration waves, beginning with the Vietnamese families in the early 1980s. With the change in apartment housing rules in the 1980s, both the community and the school population changed. The demographic of Lee's student body shifted significantly in the 1990s, as students from the south zone (Gulfton area) who are a majority Mexican and Central American immigrants and/or sons and daughters of Hispanic immigrants became the overwhelming majority of the student body. Lee became one of the largest 5A high schools in the region by the late 1990s.
