Gwinnett County is well on its way to reaching 1 million residents, officially crossing the 900,000 mark last year, the Atlanta Regional Commission said in August.

While singles, couples and families without school-aged children make up the majority of the population — the ARC’s annual Regional Snapshots population estimates report showed 910,700 people call Gwinnett home — students comprise about 20 percent of the county’s residents, meaning as the county’s population grows, the schools are becoming more and more crowded.
