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 median household income by the race/ethnicity of householders.

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

This Indicator measures the percent of renter households that are considered rent burdened by the race/ethnicity of the householder. Households that rent their homes are considered to be cost burdened when a household spends more than 30% of its annual household income on rent.

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.

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.

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.

This Indicator measures the percent by race/ethnicity of Prime contractors for construction and professional services contracts who received under $100,000. Additional data is provided on the average amount received by these contractors. Data is from fiscal year 2015-16 and the date used to assign contracts to a fiscal year is the date that the compliance analysis was completed, or the review date. The dollar amounts represent the initial award; any negotiated bid amounts or change orders are not taken into account. The initial award is adjusted to how much of the total contract went to the Prime as opposed to Subprime contractors.

This Indicator measures the percent of the population living at or below the federal poverty level, as defined by the U.S. Department of Health and Human Services. (Source: https://aspe.hhs.gov/poverty-guidelines)
