The demand for new workers in STEM (science, technology, engineering and mathematics) occupations in Arizona is a function of net job growth in these occupations in the state and the number of workers leaving STEM jobs in Arizona. Employees may leave their position for various reasons, including to retire, to move out of the state, or to change their profession. The supply of new workers in STEM occupations in Arizona is a function of the number of new college graduates in related majors, the number of workers moving to the state who are qualified to fill STEM jobs, and the number of Arizonans who are qualified to fill STEM jobs moving from a non-STEM to STEM occupation.

The war on poverty during the 1960s succeeded, cutting the national poverty rate in half by the early 1970s. Since then, however, the poverty rate of Americans under the age of 65 has increased. The poverty rate has climbed particularly among children; compared to an average of 15.5 percent during the 1971-to-1975 economic cycle, the poverty rate in each of the three cycles since 1982 averaged between 18 percent and 21 percent. One-in-five children lives in poverty and Arizona has consistently experienced higher poverty rates than the national average for all age groups except seniors.
