These 11 maps present precisely how San Francisco’s supervisor districts will likely be redrawn
San Francisco has a new set of supervisor district boundaries. After a tumultuous process, filled with claims of gerrymandering, walk-outs and missed deadlines, the redistricting task force voted Thursday to adopt its final map.
Each of the 11 districts saw changes to its boundaries in order to balance the city’s population growth over the last decade. But districts with disproportionate population changes have entire neighborhoods shifting. As a result, some residents will find themselves in different districts, with new representatives. As of yesterday, the new boundaries are in effect and will remain in place for ten years, until the next round of redistricting.
We mapped each district’s boundary changes and highlighted the biggest shifts in terms of geography and demographics.
district 1
Includes the Richmond District and Seacliff. Currently represented by Connie Chan.
Demographic changes to the district’s citizen voting age population
| Old boundaries | New boundaries | Difference | |
|---|---|---|---|
| White | 45.6% | 47.2% | +1.6pp |
| Asian | 42.6% | 41.3% | -1.4pp |
| Hispanic | 7.2% | 7.2% | -0.1pp |
| Black | 3.1% | 2.9% | -0.2pp |
District 1, currently represented by Connie Chan, has historically been made up of what is considered the Richmond District. But for the first time in decades, the district will also include Seacliff, a predominantly white and affluent neighborhood which used to be part of District 2 (under supervisor Stefani).
Some residents of the Richmond neighborhood voiced concerns about this decision, saying that it could cause the district to become more politically moderate and dilute the voting power of Asians who live in the Richmond. The addition of Seacliff and other neighborhoods immediately south of the Presidio shifts the district demographic more white by about two percentage points and less Asian by 1.4 points. As a result, the difference in the share of Asian and white residents grows from three to six points, with whites making up 47% of the voting age population, compared to 41% of Asians.
district 2
Includes the Presidio, Pacific Heights, Presidio Heights, the Marina. Currently represented by Catherine Stefani.
Demographic changes to the district’s citizen voting age population
| Old boundaries | New boundaries | Difference | |
|---|---|---|---|
| White | 74.6% | 72.6% | -2.0pp |
| Asian | 16.6% | 17.9% | +1.4pp |
| Hispanic | 6.3% | 6.3% | +0.0pp |
| Black | 1.8% | 2.5% | +0.7pp |
District 2, currently represented by Catherine Stefani, is along the city’s northern border and includes the Presidio, Presidio Heights, the Marina and Pacific Heights. The new boundaries move Seacliff out of the district into District 1 and parts of Russian Hill into District 3. Its southern boundaries extend into neighborhoods North of the Panhandle and just above Hayes Valley, but avoid incorporating Japantown and the Western Addition.
These changes mean the district will have a slightly larger share of people who identify as Asian. Still, white residents make up nearly three-quarters of the voting age population, as it did under the old boundaries.
district 3
Includes North Beach, Chinatown, Union Square/Financial District and Russian, Nob and Telegraph Hills. Currently represented by Aaron Peskin.
Demographic changes to the district’s citizen voting age population
| Old boundaries | New boundaries | Difference | |
|---|---|---|---|
| White | 47.5% | 49.4% | +1.9pp |
| Asian | 40.2% | 38.0% | -2.2pp |
| Hispanic | 6.9% | 7.0% | +0.1pp |
| Black | 3.8% | 3.9% | +0.1pp |
District 3 is located at the northeast corner of the city and encompasses neighborhoods east of Van Ness Avenue and north of Market Street, including North Beach, Chinatown, and Russian, Nob and Telegraph Hills. The district is represented by Aaron Peskin.
While preliminary draft maps proposed moving entire neighborhoods into the district, the final boundaries mainly extend the northwest border to include all of Russian Hill. The district will see a small increase in people who identify as white.
district 4
Includes the Outer Sunset. Currently represented by Gordon Mar.
Demographic changes to the district’s citizen voting age population
| Old boundaries | New boundaries | Difference | |
|---|---|---|---|
| Asian | 54.3% | 54.5% | +0.3pp |
| White | 35.0% | 34.9% | -0.0pp |
| Hispanic | 7.3% | 7.1% | -0.1pp |
| Black | 1.8% | 1.7% | -0.0pp |
Represented by Gordon Mar, District 4 consists primarily of the Outer Sunset — the area west of 17th Avenue, bounded by Golden Gate Park to the north and Lake Merced to the south. The new boundaries keep the district relatively unchanged. Some areas just north of the lake and parts of Golden Gate Park are now included in the district, but the demographic makeup of the electorate remains largely the same.
district 5
Includes the Tenderloin, Japantown, Western Addition, Haight Ashbury and Hayes Valley. Currently represented by Dean Preston.
Demographic changes to the district’s citizen voting age population
| Old boundaries | New boundaries | Difference | |
|---|---|---|---|
| White | 60.4% | 53.5% | -6.9pp |
| Asian | 20.2% | 20.8% | +0.6pp |
| Black | 9.1% | 12.6% | +3.5pp |
| Hispanic | 8.5% | 10.6% | +2.1pp |
District 5, represented by Dean Preston, is among the districts with the largest changes, both in terms of geography and population. Under the new map, the district is now made up of the Tenderloin, Japantown, Western Addition and Haight Ashbury, and no longer includes Cole Valley and parts of the Inner Sunset.
As a result, the share of white voters in District 5 falls by seven percentage points, while the Black and Hispanic shares grow by 3.5 and 2 points, respectively. Black and Hispanic voters each comprise at least 10% of the district electorate, but the district remains majority white, at 54%.
district 6
Includes South of Market, Mission Bay and Treasure Island. Currently represented by Matt Haney.
Demographic changes to the district’s citizen voting age population
| Old boundaries | New boundaries | Difference | |
|---|---|---|---|
| White | 39.5% | 39.8% | +0.4pp |
| Asian | 34.8% | 38.2% | +3.4pp |
| Hispanic | 12.4% | 11.4% | -1.0pp |
| Black | 10.5% | 8.5% | -2.0pp |
Under the new map, District 6 consists of SoMa, Mission Bay and Treasure Island. The Tenderloin, which has long been included in this district, moves to District 5 (under Dean Preston) — despite objections from the LGBTQ and Filipino communities.
This move leads to a decrease in the Black and Hispanic voter shares by 1-2 points and an increase in the Asian share by more than three points. Asians now make up 38% of the voting age population, roughly equal to the white share (40%).
District 6 will soon be represented by a new supervisor, following current supervisor Matt Haney’s win in the run-off election for Assembly District 17 earlier this month. Mayor London Breed will appoint a new supervisor to represent the district until the November midterms, when representatives for the even-numbered districts will be up for election.
district 7
Includes the Inner Sunset, West Portal, Forest Hill and Parkmerced. Currently represented by Myrna Melgar.
Demographic changes to the district’s citizen voting age population
| Old boundaries | New boundaries | Difference | |
|---|---|---|---|
| White | 45.9% | 48.2% | +2.3pp |
| Asian | 37.7% | 35.0% | -2.7pp |
| Hispanic | 10.9% | 11.2% | +0.3pp |
| Black | 4.0% | 4.0% | -0.0pp |
Represented by Myrna Melgar, District 7 includes the Inner Sunset, West Portal, Forest Hill and Parkmerced neighborhoods. The new boundaries largely remove areas just north of Lake Merced (now part of District 4) and add parts of the Inner Sunset that were previously in District 5.
By adding the several blocks in the Inner Sunset, the overall demographic shifts less Asian and more white by about 2-3 points. White voters still make up the largest race group, at 48%, but by a larger margin than previously — it is now 12 points greater than the Asian share (38%).
district 8
Includes Cole Valley, Duboce Triangle, the Castro, Diamond Heights, Noe Valley and Glen Park. Currently represented by Rafael Mandelman.
Demographic changes to the district’s citizen voting age population
| Old boundaries | New boundaries | Difference | |
|---|---|---|---|
| White | 66.2% | 68.7% | +2.5pp |
| Asian | 17.1% | 16.4% | -0.8pp |
| Hispanic | 11.4% | 10.5% | -0.9pp |
| Black | 4.0% | 3.6% | -0.4pp |
District 8, which is represented by Rafael Mandelman, largely includes Cole Valley, the Castro, Diamond Heights, Noe Valley and Glen Park. The biggest changes under the new map is the addition of Cole Valley (which used to be part of District 5) and several blocks on the district’s eastern edge moving to District 9 (under supervisor Hillary Ronen).
As a result, the share of white voters grows by almost three percentage points to make up nearly 70% of the district electorate. Meanwhile, representation among Asians, Hispanics and Blacks decreases.
district 9
Includes the Mission, Bernal Heights and the Portola. Currently represented by Hillary Ronen.
Demographic changes to the district’s citizen voting age population
| Old boundaries | New boundaries | Difference | |
|---|---|---|---|
| White | 40.2% | 41.9% | +1.7pp |
| Asian | 27.2% | 25.3% | -1.8pp |
| Hispanic | 26.8% | 26.2% | -0.5pp |
| Black | 4.8% | 4.9% | +0.2pp |
District 9, which is currently represented by Hillary Ronen, comprises the Mission, Bernal Heights and the Portola. While previous draft maps proposed changing entire neighborhoods in the district, the final map shifts the district boundaries around its borders — several blocks east and west of the Mission are added, while areas between the Portola and Excelsior District are removed.
The district’s Asian share decreases by about two percentage points, while white representation grows by a similar amount. Hispanic voters now make up the second largest race group (26%), surpassing the Asian share (25%).
district 10
Includes Potrero Hill, Bayview-Hunters Point and Visitacion Valley. Currently represented by Shaman Walton.
Demographic changes to the district’s citizen voting age population
| Old boundaries | New boundaries | Difference | |
|---|---|---|---|
| Asian | 42.2% | 42.2% | -0.0pp |
| White | 21.7% | 21.0% | -0.6pp |
| Black | 18.9% | 19.6% | +0.7pp |
| Hispanic | 14.5% | 14.5% | -0.1pp |
District 10 runs along the east edge of the city, spanning Potrero Hill, Bayview-Hunters Point and Visitacion Valley. Though a preliminary map considered removing Potrero Hill, the final boundaries keep all of the original neighborhoods in the district. As a result, the voter demographic remains largely unchanged. Shamann Walton represents this district.
district 11
Includes Excelsior, Oceanview and Outer Mission. Currently represented by Ahsha Safai.
Demographic changes to the district’s citizen voting age population
| Old boundaries | New boundaries | Difference | |
|---|---|---|---|
| Asian | 56.0% | 56.6% | +0.6pp |
| Hispanic | 22.1% | 21.1% | -0.9pp |
| White | 15.3% | 15.8% | +0.6pp |
| Black | 5.5% | 5.4% | -0.1pp |
District 11, represented by Ahsha Safai, mainly encompasses Oceanview and the Excelsior District. The new map extends the district’s northern and eastern borders by a few blocks, resulting in some small demographic shifts — the share of Asian and white voters increases, while Hispanic representation decreases.
