Do you believe state-funded infrastructure projects significantly improve long-term economic growth in your community?

Researchers have found that $39 billion in infrastructure spending from fiscal year 2021 through 2028 is driving substantial economic activity in South Carolina. The investment generates $1.70 in economic activity for every dollar spent while supporting over 38,000 jobs annually.

Why it matters

As South Carolina leads the nation in population growth, these infrastructure improvements are essential to support expanding economic demands. The study indicates that such spending not only creates immediate jobs but also lays the groundwork for long-term regional stability.

The study highlights that $39 billion in investment yields $66.7 billion in total economic output, with an economic multiplier of $1.70 for every $1 spent. These projects support an average of 38,056 jobs per year with an average annual compensation of $72,678.

The details

The analysis accounts for direct spending in transportation, water, wastewater, broadband, and stormwater agencies, focusing on how these systems accommodate rapid population growth. By upgrading these critical networks, the state expects to boost annual employment growth rates from 1.3 to 1.8 percent over the coming decade.

Fiscal year 2021 through 2028 marks the period covered by the analysis.
The infrastructure impact study was published in 2026.
Projected permanent job growth is expected to span from 2026 through 2036.

Macro View

The analysis quantifies how state-level infrastructure development mirrors the outcomes of federal initiatives like the 2021 Infrastructure Investment and Jobs Act. It demonstrates that regional investments align with national efforts to drive long-term GDP growth through structural improvements.

Residents can expect these investments to stabilize local economies and create nearly 140,000 potential permanent jobs over the next decade. The initiative directly impacts household budgets by providing higher-paying roles, as average compensation for these jobs is 15 percent above the statewide average.

The takeaway

Strategic investment in public works continues to be a primary driver for state economic health and employment stability. Residents should monitor future regional project announcements to understand how infrastructure shifts will influence local market opportunities in their counties.
