What term describes the number of persons employed in businesses that represent the economic foundation of an area?

Base Employment refers to the number of individuals employed in industries that are fundamental to the economy of a specific area. These industries, often termed "base" or "export" industries, typically produce goods or services that are sold outside the local economy, bringing in revenue and stimulating further economic activity within the area. This employment sector is crucial because it helps sustain other jobs and services in the community, forming the backbone of the local economic structure.

Understanding base employment is vital for real estate professionals, as it can significantly influence housing demand, commercial development, and overall market stability. In contrast, the other terms provided do not specifically address the concept of employment tied to the economic foundation of an area. Gross employment may refer to total jobs without considering their economic impact, net employment addresses hires and separations without focusing on foundational industries, and standard employment lacks specific relevance to the foundational aspect of the economy.
