A. SUMMARY This dataset contains San Francisco Board of Supervisor district boundaries approved by the San Francisco Redistricting Task Force in April 2022 following redistricting based on the 2020 Decennial Census. B. HOW THE DATASET IS CREATED The dataset was created from the final map submitted by the San Francisco Redistricting Task Force. Boundaries in this map were decided using data from the 2020 Census on the number of people living in each census block in the City and County. This data includes the number of individuals incarcerated in facilities under the control of the Department of Corrections and Rehabilitation based on their last known residential address. This information is made available by the Statewide Database based on U.S. Census Bureau Census Redistricting Data (P.L. 94-171). These map boundaries were trimmed to align with the city and county's physical boundaries for greater usability. This trimming mainly consisted of excluding the water around the City and County from the boundaries. C. UPDATE PROCESS Supervisor District boundaries are updated every 10 years following the federal decennial census. The Supervisor District boundaries reflected in this dataset will remain unchanged. A new dataset will be created after the next decennial census and redistricting process are completed. The dataset is manually updated as new members of the Board of Supervisors take office. The most recent manual update date is reflected in the 'data_as_of' field. Once the redistricting process is completed after the next decennial census and a new dataset is published, this dataset will become static and will no longer be updated. D. HOW TO USE THIS DATASET This dataset can be joined to other datasets for analysis and reporting at the Supervisor District level. If you are building an automated reporting pipeline using Socrata API access, we recommend using this dataset if you'd like your boundaries to remain static. If you would like the boundaries to automatically update after each decennial census to reflect the most recent Supervisor District boundaries, see the Current Supervisor Districts dataset or the Current Supervisor Districts (trimmed to remove water and other non-populated City territories) dataset.

C. UPDATE PROCESS This is a static dataset

D. HOW TO USE THIS DATASET This dataset is a many-to-many relationship between supervisor districts and ZIP codes. A single supervisor district can contain or intersect with multiple ZIP codes and similarly, a single ZIP code can be in multiple supervisor districts. This dataset does not contain geographic boundary data (i.e. shapefiles/ GEOMs). The datasets below containing geographic boundary data should be used for analysis of data with geographic coordinates.

A. SUMMARY This dataset contains a version of the current San Francisco Board of Supervisor district boundaries that have been trimmed to exclude non-populated City and County territory that is outside of the contiguous land mass of the City and County. This excludes for example City and County land in the Farallon Islands, Angel Island, and Alameda County, The underlying official current Supervisor District boundaries are available in the Current Supervisor Districts dataset. B. HOW THE DATASET IS CREATED This dataset will be updated to reflect the most current Supervisor District boundaries available. It currently reflects the same boundaries found in Supervisor Districts (2022). More information on how this was created can be found in the datasets by year: Supervisor Districts (2022) and Supervisor Districts (2012) C. UPDATE PROCESS Supervisor District boundaries are updated every 10 years following the federal decennial census. The Supervisor District boundaries reflected in this dataset will be manually updated after the next decennial census in 2030. The dataset is also manually updated as new members of the Board of Supervisors take office. The most recent manual update date is reflected in the 'data_as_of' field. D. HOW TO USE THIS DATASET This dataset can be joined to other datasets for analysis and reporting at the Supervisor District level. It is meant to facilitate visualization and mapping focussed on the contiguous land mass of the City & County and Treasure Island. If you are building an automated reporting pipeline using Socrata API access, we recommend using this dataset if you would like the boundaries to automatically update after each decennial census to reflect the most recent Supervisor District boundaries. If you'd like your boundaries to remain static, see the Supervisor Districts (2022) dataset. E. RELATED DATASETS Current Supervisor Districts Supervisor Districts (2022) Supervisor Districts (2012)

Five (5) Supervisoral Districts of San Diego CountyRedistricting takes place every 10 years after the federal census. District boundaries for federal, state and local elected offices are redrawn to reflect new population data and shifting populations. The County’s district boundaries will change so the five County supervisors elected to represent those districts each serve about 650,000 residents and reflects the County’s diverse population. Fourteen people were selected for the County's IRC. The process will act independently from the influence of the Board of Supervisors and reasonably represent the County’s diversity.On January 12, 2022, the IRC approved technical changes to the 2021 Redistricting Plan and Final Report adjusting boundaries of the supervisorial districts of the County of San Diego Board of Supervisors(https://www.sandiegocounty.gov/content/sdc/redistricting/2021-redistricting-plan-map1.html)The Board adopted the redistricting ordinance on December 14, 2021 (https://www.sandiegocounty.gov/content/dam/sdc/redistricting/docs/ircmeetings/irc-meeting-12-14-21/Item%2005%20-%20Resolution%20Adopting%20Final%20Report%20re-%20Final%20Redistricting%20Plan%20-%20SIGNED.pdf)
