Professional, Scientific and Technical Services in the US Industry Data and Analysis
Professional, scientific and technical services have grown steadily, even amid inflationary spikes and interest rate uncertainty. The need for quality, proficient and well-versed services in field such as corporate law were significant drivers of sector demand, as businesses sought out expert services to address core issues such as tax guidance. While inflationary spikes, which peaked at 9.1% in 2022 per the BLS, curtailed demand within the construction sectors, this trend began to show reversal in recent years. A 0.85% rate cut in 2024, per data from the Federal Reserve, provided critical respite to the construction space, as architects, engineers, lawyers and interior designers enjoyed rebounding interest among residential and nonresidential clients alike. Revenue grew at a CAGR of 2.7% to an estimated $3.2 trillion over the past five years, including an estimated 0.5% slip in 2025 alone. Profit remains stable for the sector, although challenges in navigating new tariffs curtailed growth.
