  2. Healthy Kids Healthy Oakland Opportunity Mapping Update TASK FORCE GOAL To develop an expanded data framework, including non-traditional indicators and aligned data tools to support a full-service community school district and the needs of the whole child. • Develop a map-based data tool to explore alignment of district-wide socio-economic indicators with school and student based data

  3. Healthy Kids Healthy Oakland Opportunity Mapping Update • Current scope of work: • Create map-based tool integrating various school & community databases into a geographic context within an ArcGIS software environment

  4. Healthy Kids Healthy Oakland Opportunity Mapping Update • Current scope of work: • Task #1: Create district-wide base maps • US Census Bureau American Community Survey 5 Year Block Group estimates

  5. Healthy Kids Healthy Oakland Opportunity Mapping Update The American Community Survey (ACS) is an ongoing statistical survey by the U.S. Census Bureau, sent to approximately 250,000 addresses monthly (or 3 million per year) It regularly gathers information previously contained only in the long form of the decennial census.

  7. Healthy Kids Healthy Oakland Opportunity Mapping Update • 2005-2009 Map • 2000 Map • 2005-2009 vs 2000 Data: • Estimate & Margin of Error

  8. Healthy Kids Healthy Oakland Opportunity Mapping Update Statistical Significance. The determination of whether the difference between two estimates is not likely to be from random chance (sampling error) alone. Standard Error. The standard error is a measure of the deviation of a sample estimate from the average of all possible samples. Margin of Error (MOE). An MOE is the difference between an estimate and its upper or lower confidence bounds. Confidence bounds can be created by adding the MOE to the estimate (for the upper bound) and subtracting the MOE from the estimate (for the lower bound). All published ACS MOEs are based on a 90 percent confidence level. 2005-2009 Estimate Range: 29.8 to 30.4 (30.1-0.3) to (30.1+0.3) 2000 Estimate Range: 27.0 to 27.4 (27.2-0.2) to (27.2+0.2) Difference: 2.9 (30.1-27.2)
