In the early 1990s, a study of the Tanque Verde Creek by Dr. Julie Stromberg and others described the relationship between the depth to groundwater and the health of the mesquite woodland habitat in the area. This report revisits the Stromberg study to describe variations in groundwater levels since the report was completed early last decade. They identified around 3,000 acres of riparian vegetation in the Tanque Verde-Agua Caliente shallow groundwater zone.

The educational attainment in 2000 of the entire 25-or-older population in Arizona was similar to the national average and ranked in the middle of the states. Arizona compared less favorably to two sets of comparison states: “competitor” states defined by the Greater Phoenix Chamber of Commerce and “new economy” states identified by the Milken Institute. In 1990, however, Arizona’s educational attainment had exceeded the national average. Arizona ranked among the bottom 10 states in the 1990 to 2000 gain in educational attainment. Among both the entire population and those active in the labor force in 2000, the
educational attainment of Arizona residents 55 or older exceeded that of their peers nationally.
