As part of our investigation into the variations in suspension practices and outcomes across OUSD schools, we mapped the location of each student and aggregated their data to the census tract they live in. We then symbolized each tract (darker color indicates higher rate) with the rate of suspension for the African American males in that tract for the 2010-2011 academic year. The second map below shows the rate of suspension for ALL students per school using the exact same break values in the tract coloring. We think these maps clearly illustrate the massive differential in suspension rates for African American male students compared to students overall and also serve to show how outcomes vary widely across the city. There were only three tracts with overall suspension rates in the second highest range as the rates for African American males. Again we see an east/west bi-modal distribution: African American males are suspended at high rates across the city, but the overall rates in the central flat-lands are quite positive in comparison to the rest of the city. From the first map, the most striking outcome is that in almost half the city's neighborhoods, African American males are suspended at a rate of at least one in five students in a single year.
As with most outcome data it is important to consider the data from both a facility (school) and a community (tract) perspective. To view the maps of suspension rates by school read this post. To read the full attendance report, click here.
Note that for relevance we removed tracts with fewer than 10 African American males as these neighborhoods' data can easily skew the results and create misleading figures that are not statistically stable (numbers that cannot be trusted for interpretation).
