<br />. <br /> <br />Power Market Survey - Colorado River Storage Project <br /> <br />Estimated Future Popul~tion <br />In estimating the future population consideration was given to the <br />past trends discussed in the foregoing, to potential developments of the <br />region's natural resources, and to the economic and industrial growth <br />anticipated as discussed earlier in this section. For the period through <br />1965 primary reliance was placed on the Bureau of Census Current Population <br />Reports, Series P-25, No. 110 and No. 145. <br /> <br />The population of an area. is closely related to the number of persons <br />in its labor force. Employment opportunities in an area attract labor <br />force and thus encourage in-migration of population to the area., while <br />increases in population both natural and migratory enlarge the market for <br />goods and services and, therefore, necessitate a larger labor force. Pop- <br />ulation and labor force are thus interrelated, and in mak~ estimates <br />for the future, neither can logically be considered independently of the <br />other. . <br /> <br />. <br /> <br />The relationship between population and labor force varies between <br />subareas, but the general trend throughout the region in recent ;years is <br />toward smaller family units and a larger percentage of the population in <br />the labor force. In 1950, about 35 percent of the population was in the <br />labor force as compared to 40 percent for the nation. By 1980 it is esti- <br />mated the regional percentage will increase to about 36 percent. <br /> <br />On the basis of the above considerations, it is estimated that the' <br />1980 population of the region will approximate 8,209,000 -- an increase <br />of 175 percent over 1940 and 116 percent over 1950. <br /> <br />G - Income <br /> <br />The amount and distribution of the income of a region are important <br />factors in the intelligent consideration of markets, including the market <br />for electric power. High per capita income usually signifies a high <br />standard of living and indicates a good market for electric appliances and <br />conveniences. <br /> <br />Statistics on per capita income are available only on a statewide <br />basis. Table 4 shows the per capita income of the United States and of <br />the eight states, all or parts of which are in the power market region. <br />Tbe figures shown are for the entire state; therefore, ilie data for <br />. Idaho, Nevada, and Texas may not be exactly indicative of the parts of <br />those states included in the study. <br /> <br />. <br /> <br />- 17 - <br /> <br />
