We have provided a community supported open data website to help make it easier for you to find data: http://data.openoakland.org.
You can also find public data for the City of Oakland at: https://data.oaklandnet.com
Or data from Alameda County at http://data.acgov.org
If you cannot find what you need you can request help, if we know of a data source we'll happily refer you to the location. We do not perform custom data acquisition support.
