. . . . Power Market Survey - Colorado River StoragEl Project It is anticipated that employment in manufacturing will increase considerably in all areas. In Area II, Arizona,an increase of 565 per- cent from 1950 to 1980 is anticipated. It is estimated that the manu- facturing empioyment for the region will exceed 400,000 by 1980, as compared to about 131,000 in 1950. Climatic advantages, availability '01' raw materials, and the rapidly eJ<panding western market for finished products, are factors which were given weight in arriVing at the esti- mates. The "All Other" classification of the labor force is expected to increase from 983,002 workers in 1950 to 2,339,434 in 1980, or an in- crease of 138 percent. This subdivision in 1950 constituted 73 percent of the total labor force, and it is expected that it will include about 78 percent by 1980. In 1950 the w;) rkers in this category were distrib- uted as follows: construction, 11 percent; tranilportation, communication, and public utilities, 12 percent; wholesale and retail trade, 27 percent; .professional and related services, 13 percent; goverrunent, 8.3 percent; personal services, 8.3 percent; and miscellaneous, 20.4 perc.ent. It is expected that a similar distribution will prevail in 1980. Residential, commercial, and industrial construction is expected to be stimulated by the industrial expansion and the associated population growth. The high growth in utility electrical requirements shown else- where .in this report will cause an increase in the utilit;y labor force. Federal employment on construction projects with the associated permanent local commercial developments is expected to increase during this period. State and local goverrunent employees will increase along with the increased population and other economic expansions predicted. Because of the recrea- tional advantages of the region the tourist trade will continue to grow rapidly. Service industries which supply the needs of this transient and prosperous multitude will demand more and more of the available labor force. Other fields, such as wholesale and retail trade, which depend on popula- tion and economic activity will also require additional workers. By 1980 the total labor force will, it is estimated, amount to over 2,987,000 persons, an increase of 85 percent aver the 1955 total. F - Population The population of an area is, in general, closely related to the area's economic activities which in turn are based on its natural resources, be they mineral deposits, arable land, or geographical location. The pop- ulation also generates economic forces requiring additions to serve itself. - 13 -
