What goods-producing sector has maintained its share of total employment in the U.S. economy since the Second World War?

The construction sector is notable for maintaining its share of total employment in the U.S. economy since the Second World War. Unlike agriculture and manufacturing, which have seen significant declines in their employment shares due to advances in technology and globalization, construction has remained relatively stable. It continues to be a critical component of the economy, driven by ongoing demand for housing, infrastructure development, and commercial projects. The sector adapts to economic cycles but has consistently provided a steady number of jobs, reflecting its essential role in the economy's overall functioning and growth.

Agriculture has experienced sharp declines in employment due to mechanization, while manufacturing jobs have been outsourcing and automation. Mining, though vital, has a much smaller employment share compared to construction and has faced fluctuations due to commodity prices and demand. Thus, construction stands out for its consistent contribution to overall employment levels.
