This Indicator measures the percent of residential addresses that have been identified as “vacant” by the United States Postal Service (USPS) for at least two years. Data is collected and aggregated at the census tract level by the USPS on a quarterly basis.

This Indicator measures median household income by the race/ethnicity of householders.

This Indicator measures overall ratings for Oakland parks and compares average scores by City Council District. The overall ratings were based on an annual survey that assigned parks letter grades (A through F), which corresponded to scores (A=4, B=3, C=2, D=1 and F=0). In addition to Council District scores, the scores for parks surrounding Lake Merritt were reported as an average Lakeside score. The survey also included questions about greenery, amenities, recreation areas, and homeless encampments. For a map of the City Council Districts, see here: http://www2.oaklandnet.com/oakca1/groups/ceda/documents/image/oak044524.pdf.

This Indicator measures the percent of curbs with curb ramps that are not modern, indicating that they are non-compliant. Modern curb ramps should have all the proper elements: low slope and cross-slope, adequate width, level top and bottom landings, a detectable warning surface, and they should be directional and clear of obstructions in the curb ramp area. This is a citywide Indicator that measures conditions for individuals with physical disabilities and limited mobility.

This Indicator measures the rate of adult felony arrests by race/ethnicity adjusted for population. Rate is calculated as the number of adult felony arrests per 100,000 people of each race/ethnicity that are 18 years of age and older. To determine the number of adults of each race/ethnicity in Oakland, we took the population by race/ethnicity for all ages and multiplied by the percent of Oakland’s population that is 18 and over (80.33%). This approach was necessary due to the lack of exact data available on the 18 and over population in Oakland by race/ethnicity.

This Indicator measures the percent of employed individuals who are self-employed in their own incorporated business, professional practice, or farm.

Pollution burden is calculated by the Office of Environmental Health Hazard Assessment’s CalEnviroScreen 3.0. This tool measures pollution burden as a combined score that includes Indicators of potential exposures to pollutants and environmental conditions (e.g., ozone, pesticides, toxic releases, traffic, hazardous waste). The pollution burden scores are averaged by majority race/ethnicity of Oakland census tracts.

The measurement is the rate of teachers per 1,000 students of the same race/ethnicity in OUSD, in other words how representative are the teachers of the student population? Numbers of teachers and students were calculated from percents of the total number given in OUSD’s Fast Facts report.

Bus frequency is measured as the average number of buses per hour along routes in and surrounding census tracts. For this Indicator, 100ft buffers were created around each group of census tracts in order to capture bus routes that did not fall completely inside census tract boundaries but were still important to include because they were very close. For each group of census tracts, bus frequency was averaged, taking into account the length of the route.
