The state uses official population figures to determine how much each city receives in shared revenue from sources such as income, sales and vehicle taxes. The competitive nature of the system is pitting high-growth communities like Gilbert and Peoria against more-established cities like Phoenix and Mesa, The Arizona Republic reported (http://bit.ly/1HE9nvH ). When three small communities with limited resources — Prescott Valley, Page and Chino Valley — proposed the same legislation to the League of Arizona Cities and Towns last summer, the resolution was rejected. Phoenix and Mesa are pushing for adjustments to the state's population estimate process to improve accuracy in lieu of an expensive door-to-door count.
