Almost 24,000 workers were employed for one full year for every billion dollars spent in 1980 for new construction such as buildings, houses, and highways. More than half of the jobs were created in industries that produce, sell, and deliver materials and equipment required for construction, such as the manufacturing, trade, transportation, and mining industries. (See table 1.) The 13 activities surveyed covered more than half of the value of new construction. Each activity created roughly an equivalent number of jobs in the economy. The fewest jobs were generated in commercial office buildings and civil works land projects (nearly 22,000 jobs per billion dollars) and the largest number were in public housing (26,000 jobs).
