  1. SCHOOL ABSENCES: A CONSEQUENCE OF AIR POLLUTION IN CALIFORNIA?

  2. ASSESSING THE PROBLEM • “The state calculates that meeting the hourly and daily ozone standards will alleviate 3.3 million school absences each year for California’s kids.” • -The Environmental Working Group • Goals: • To utilize GIS as a tool to illustrate the health impacts of poor air quality on California’s population. • To determine if there is a link between poor air quality and school absences • To determine if there are significant impacts to public school funding

  3. 160-120 Days of poor AQ – 1558 Schools 91-105 Days of poor AQ – 343 Schools 76-90 Days of poor AQ – 3335 Schools 61-75 Days of poor AQ – 1888 Schools **Schools not heavily impacted: 5523

  4. Total Number of Asthma Hospitalizations

  5. According to the Rand • Corporation, in 2009, there • were 343 public schools • that had a daily attendance • under 90%.

  7. Skills Used: • Slide 3: inset map • Slide 7: aggregating attribute fields • - “Perc_ada < 90” • - Percent average daily attendance < 90% • Slide 6: creating indices • - “Co_perc_ad * co_enrollment = avg_ada” • - (average % daily attendance) * (county enrollment) = • (average number of kids per day in attendance) • - co_enrollment – avg_ada= avg_absences • - (county enrollment) – (avg. number of kids per day in • attendance) = (avg. number of daily absences) • Slide 7: point graduated symbol • Slide 7: geocoding • Slide 4: geocoding and graph
