Three trustee-area map options presented for Center Joint Unified; none produce majority‑minority districts

At a meeting on trustee‑area mapping for Center Joint Unified, the district’s demographer presented three proposed map scenarios and said none of them create a majority‑minority trustee area given current population and census‑block configurations. The presenter walked trustees through citizen voting‑age population (CVAP) figures, population variance calculations and tradeoffs between keeping rural areas intact versus minimizing population deviation.

The presenter said the district returned about 29,511 census responses and that, with five trustee areas, an ideal trustee area population would be about 5,902 people. He described the legal check required by AB 764, explaining that the demographer must attest whether maps could create or dilute majority protected‑class areas and that CVAP data are used to avoid packing or cracking protected groups. "In no way, shape, or form were we able to create a concentration that would constitute a majority area for any of those ethnic classes," the presenter said.

The presentation summarized each scenario and its overall population variance: Scenario 1 had a 9.1% variance and required extending into Sacramento County to balance growth; Scenario 2 emphasized rural areas and produced a 7.6% variance; Scenario 3 grouped rural blocks more tightly and produced the lowest variance, 4.6%. The presenter highlighted which trustee areas in each scenario had above‑average CVAP shares for Hispanic, Black/African American and Asian residents, but reiterated that none reached a majority threshold under the reviewer’s CVAP analysis.

The presenter also addressed a map submitted by Trustee Ballen, saying the submitted configuration would produce an outsized variance (about 123%), shortfalling Trustee Area 5 by roughly 3,400 people and overpopulating Trustee Area 1 by about 3,800 — outcomes that exceed the typical 10% threshold used to judge balance. The presenter described how he adjusted the lines in Scenario 1 to add roughly 2,300 people into Trustee Area 5 (bringing that area closer to the 5,902 ideal) and said those additions necessarily shifted population counts in neighboring areas.

Explaining technical limits, the demographer said the team follows U.S. Census block boundaries and avoids splitting blocks because doing so would require assumptions about the internal distribution of protected populations. "We didn't split any," he said, describing the use of the smallest available census units to minimize guesswork when drawing lines.

The presenter closed by showing a side‑by‑side comparison of all three scenarios and inviting feedback and requests to view larger maps. He said the process remains open for adjustments through the final adoption and that the group would reconvene on April 9 for further consideration and possible selection of a final map.
