Illinois is projected to see $57 billion in data center construction through 2035, with 121,000 jobs created during the build phase.[^1]

Researchers estimate only 2,800 of those positions will remain once the facilities are operational.[^2]

Census Bureau construction spending figures for August show private data center construction increased 73% year over year, rising from $49.05 billion to $84.95 billion.[^6]

Multiple local governments have enacted or proposed temporary pauses on new data center approvals. None of these rules affect construction projects already underway.[^3]

Pima County, Arizona voted 3-2 on September 22 to approve a 120-day moratorium on new data centers in unincorporated areas.[^5] Charlotte, North Carolina city council has scheduled a public hearing for October 12 to extend its existing pause by 11 months to October 2027.[^4]
