<br />MAY lQ82 <br /> <br />Over the past 50 years Montezuma County has increased from 7,798 to <br /> <br />1- <br /> <br />16,510 people. During this time there have been significant variations in <br /> <br />population although the area has remained generally rural. <br /> <br />Initial growth was directly related to mining. Agriculture did not <br /> <br />become significant until after 1890, when irrigation water was first <br /> <br />delivered to Montezuma Valley. Until 1950, most of the population growth <br /> <br />was a result of the expanding agricultural industry. Growth was relatively <br /> <br />uniform and gradual until the decade of 1950-60 when oil exploration caused <br /> <br />a sharp increase from 9,991 to 14,024 during this 10-year period. <br /> <br />Following 1960, oil explorations dwindled and the population declined <br /> <br />sharply, although it remained above the 1950 level. Between the years 196u <br /> <br />and 1970, the population in Montezuma county decreased while population in <br /> <br />the State increased. However from 1970 to 1980, the population again grew <br /> <br />significantly due to renewed oil interest and construction of the Dolores <br /> <br />Project. <br /> <br /> Population change 1930-1980 <br />Year Nontezuma Percent Colorado Percent <br /> County Change Change <br />1930 7,798 1,035,791 <br />1940 10,463 34 1,123,296 8 <br />1950 9,991 -5 1,325,089 18 <br />1960 14,024 40 1,753,947 32 <br />1970 12,024 -14 2,209,596 26 <br />1980 16,510 37 2,88/l,834 31 <br /> <br />Indians and Spanish Americans, the largest minority groups, comprise 18 <br /> <br />percent of the County population. Approximately 1,651 Indians live in the <br /> <br />county; most of them belong to the Ute Mountain Indian Tribe at Towaoc, 11 <br /> <br />miles south of Cortez. Of all Indians in the area, 90 percent live in this <br /> <br />community which is outside of the McElmo study area. Also, the 1980 census <br /> <br />estimated that 1,352 people in the area are of Spanish-American origin, with <br /> <br />nearly 55 percent living in the city of Cortez. <br /> <br />III-14 <br /> <br />ro (,1 S 5 0 <br />,) \.,,' J. <br />
