<br />Section 5 <br />Consumptive Water Needs in the North Platte Basin <br /> <br />5.1.1.2 Population Projections <br /> <br />Future population projections were obtained from the <br />Colorado DOLA, Demography Section. This dataset <br />contains county population projections from 2000 to 2030 <br />in annual increments. Populations for counties that lie <br />within two or more basins were allocated to the <br />respective basins based on estimates from known <br />population centers within each basin. <br /> <br />From 2000 to 2030, Colorado's population is projected to <br />increase by about 2.8 million additional people - a <br />65 percent increase - to a 2030 population of over <br />7.1 million. Aggregated basin summaries of the data are <br />presented in Figure 5-1 and Table 5-2. The vast majority <br />of the state's population in 2030 will live in the South <br />Platte and Arkansas Basins. <br /> <br />Yampa/White/Green <br />Colorado <br />Gunnison <br />Dolores/San Juan <br /> <br />Arkansas <br /> <br /> <br />Rio Grande <br /> <br />Figure 5-1 <br />Relative 2030 Populations in Each Basin <br /> <br />Table 5-2 Population Projections by Basin <br /> <br />On a basin level, West Slope growth rates are projected <br />to be the highest, with the Colorado Basin population <br />almost doubling and Gunnison River and Dolores/San <br />Juan/San Miguel Basins' populations increasing by 82 <br />and 89 percent, respectively. <br /> <br />5.1.1.3 Estimates of Per Capita M&I Water Use <br /> <br />Numerous factors affect per capita water use rates, and <br />through the course of SWSI, differences in the water use <br />components that are included or excluded from individual <br />entities' per capita estimates clearly affected the resulting <br />values. Per capita water use rates are in large part a <br />function of: <br /> <br />. Number of households <br /> <br />. Persons per household <br /> <br />. Median household income <br /> <br />. Mean maximum temperature <br /> <br />. Total precipitation <br /> <br />. Total employment <br /> <br />. Ratio of irrigated public land areas (e.g., parks) to <br />population in service area <br /> <br />. Level of tourism and/or second homes <br /> <br />. Ratio of employment by sector (e.g., agriculture, <br />commercial, industrial) <br /> <br />.
