California Senate District boundaries comprised of active, deferred, and accelerated district boundaries until the 2024 Election.
<DIV STYLE="text-align:Left;"><DIV><DIV><DIV STYLE="font-size:12pt"><P><SPAN>Senate Districts in California with boundaries showing active, deferred, and accelerated district boundaries until the 2024 Election. This data is available at a public level for everyone to use.</SPAN></P><P><SPAN>The active districts are comprised of even district numbers with Senators elected in 2022. These even districts use the boundaries edited in the 2020 Census. They were finalized in 2021 so that is why the districts are referenced with that date. The first election they were ready to be used in was the 2022 Election, but not the 2020 election. </SPAN></P><P><SPAN>The 2020 Election used the boundaries of the districts created in the 2010 Census (finalized in 2011). The odd numbered senate districts used the 2011 boundaries in the 2020 election. These odd senate districts will change to the 2021 Certified districts with the 2024 election cycle. Until then the odd numbered 2011 Certified Senate districts are still active. These even and odd districts are labelled as Active Districts in the layer.</SPAN></P><P STYLE="margin:1 1 1 0;"><SPAN>Since some of these boundaries were changed, there is overlap of some of the odd and even districts. They are referred to as Accelerated Districts and they occur where an existing odd-district is overlain by a new even-district. The constituents in the accelerated areas will have two Senators who may represent them.</SPAN></P><P STYLE="margin:1 1 1 0;"><SPAN>Some of the district boundaries were changed so that there are gaps with no district coverage at all. If there is a gap in coverage, the area is referred to as a Deferred District. They occur when an area that was an even-numbered district in the 2011 redistricting plan becomes an odd-numbered district in the 2021 redistricting plan. The area does not have a Senator until the conclusion of the 2024 election when the new odd-numbered district becomes active. During the 2023-2024 session the Senate Rules Committee assigns Senators to provide constituent services in deferred areas.</SPAN></P></DIV></DIV></DIV></DIV>

The Senate Office of Demographics sent the California CRC Senate District boundaries delimited with the proper attributes. There were 3 layers (Active, Accelerated and Deferred), so these were merged into one for ease of access. This involved reprojecting to WGS 84, erasing the Accelerated polygons from the Active Districts since there was overlap there, and them Appending each layer to a new layer with a new schema. The attributes were altered to function in a single layer. Some fields were merged as well to improve simplicity and labelling properties.
