Tax Bill, Inflation, Income, and Extension

The school district has prepared a graph to show that tax growth is in line with CPI ("cost of living"), but the presentation is lacking in two regards. First, the starting year was specially chosen to support the conclusion, but it misses the bigger picture regarding the bigger picture of Batavia's financial health. See what happens when you move the starting point just one year; then the picture is not as rosy:

From 2007 to 2014, the amount of taxes the district has extended has increase by  36.8%.  The average residential tax bill (the district's portion) has increased by 20.3%.  Overall increase from inflation, according to the Consumer Price Index (CPI), has been 16.6%. Batavia's Median Household Income has increased by 1.5%.
For the heart of Batavia, the increased tax burden has well out paced their household income.
