 Featured Number
13 - The number of ozone exceedances in Maricopa County in 2008.
Ground level ozone is an ongoing problem in metro Phoenix and throughout the state. Hot, dry cities are especially prone to
high levels of ozone, which is created when heat causes a chemical reaction between substances from vehicle exhaust and industrial
emissions. In March 2008, the Environmental Protection Agency strengthened the ozone 8-hour standard to 0.075 parts per million from
0.084 parts per million, increasing health protections but making it more difficult for Arizona counties to reach compliance. In
2008, Gila, La Paz, Maricopa, Pinal, and Yuma counties all recorded one or more ozone exceedance for the year. Furthermore, most
of Maricopa County and a small portion of Pinal County were classified as nonattainment areas by the EPA. Breathing ground level
ozone can contribute to numerous health problems including acute respiratory problems and aggravation of asthma.
Announcements
As Arizona begins the second decade of the new millennium, Arizona Indicators asked its subject experts to reflect and comment
on the most important trends observed during the previous decade. Visit this special
2010 feature to get a glimpse of what lies ahead.
Many Arizona students speak a language other than English at home. Read the latest issue of
Policy Points for a new analysis of how
these non-English home language students perform on the Arizona Instrument to Measure Standards (AIMS) test relative to their English
home language peers. Each issue of Policy Points contextualizes a pressing topic facing Arizona residents and presents key facts and figures
to inform policy choices.
New Arizona Demographic Data and Achievement Data for Students with a Home Language Other than English
Check out Population Basics for updated demographic profiles
of Arizona, our counties, and metro regions. The latest data is based on 2006-2008 estimates from the American Community Survey.
Arizona Indicators is pleased to publish a new set of indicators showing AIMS achievement data for students with a home language other than
English. Visit the expanded Education tab to see how the
AIMS pass rate is slowly increasing for non-English home language students. While data show that the achievement gap between these students and
their English home language peers is narrowing, parity is still on the too distant horizon.
