2020 Census and Redistricting Thread: California

[President Punxsutawney Phil]

I've fixed Vargas' seat. It is now up to 54.7% Latino VAP.

I've fixed Vargas' seat. It is now up to 54.7% Latino VAP.

Go to the sidebar on the right and where it says Voting Age select '2018 CVAP.' It is impossible to get a pure SD seat above 52% using that data, unless you tentacle, so I know you are using the wrong stuff. I also won't fault you since DRA added the CVAP in a stealth unannounced update, and I only discovered it 10 days ago or so. However, it's very easy to get over 50% HVAP purely in the county.

EDIT: looks like they added it in the announcement bar now, there was no such notification back when it first came out.

I got my Juan Vargas district to 52% Hispanic CVAP.

It is not a problem for me re: seeing the data you speak of because I enabled everything.

I'm trying to limit municipal splits anyway. I don't think the Latino % being just over a majority of CVAP matters too much esp. since the Asian and white % evenly split the non-Latino segments of the seat.

[I’m not Stu]

I actually managed to successfully draw LA County without sharing any districts with OC. I also did the same with San Diego. I also hate OC-SD splits.

Yep, which is why I say 47%+ is probably the magic number when it comes to CVAP (outside of the South valley), as long as whites don't pass the Hispanic CVAP total. 50% though is crucial in SD because if it is under 50% than the potential Imperial-SD pairing is back on the table. But like I said, it's presently a no-brainer to get such a seat over the 50% line that one would have to put the interests of other groups ahead of the Hispanic seat for it to require the pairing.

I also don't like La Habra being paired with Santa Ana.

[President Punxsutawney Phil]

I also don't like La Habra being paired with Santa Ana.

It is pretty good from a "keep the Central OC seat's  Latino % firmed up" perspective. It also helps produce a better Asian Belt seat.

Is my Asian Belt seat (Westminster, Garden Grove, Huntington Beach, Cypress, and Seal Beach) fine?

It is decent. Ofc I couldn't replicate it due to my differing set of county cuts but it works well enough in your map.

Mine gets more of the Vietnamese vote by taking in Huntington Beach and slightly less of Fullerton. My Asian Belt seat is mostly Vietnamese. What's yours?

I would have sent it into Cerritos but I already had two seats being shared between OC and LA, I didn't want another.

What's the largest Asian group in that district? Mine is a Vietnamese district.

I wouldn't know the largest Asian group inside the district, but I would guess still Vietnamese due to it having all of Westminster and the core of Little Saigon.

Little Saigon is mostly Garden Grove, with a small part of Westminster. Long Beach doesn't go very well with OC, except for the somewhat less liberal suburban areas near Cypress and Seal Beach (the neighborhoods near Long Beach State and along 2nd Street).

The general regional blocs of your San Diego and Inland Empire districts are really good. However, you need to clean up along municipal lines and more natural boundaries in general. Corona and some of the San Diego lines are particularly awkward. I really, really don't like districts which connect OC to the Inland Empire or the San Gabriel Valley, so I'd prefer you reconfigure OC to get rid of your CA-42 district.

Re: municipal lines, it is very hard to actually follow municipal lines due to the specific shapes of the units I'm dealing with.
It's a shame that's the case.
Re: CA-42, it was my effort at an Asian opportunity CD. I wound up having to do San Brenardino (because you don't want to violate the natural boundary now delineating many sections of CA-8) and this wound up requiring a revamp of the areas around Fontana and Ontario as I had 300k left over. I also had leftovers from Riverside County. This necessitied the shape of my current CA-41. I then used the leftovers to make the rest-of-OC, rest-of-SB, and parts-of-SE-LA CD as Asian as possible.

I probably wasn't too successful. In practice I got a CD that basically is very similar to the old CA-39.

I guess you can say Long Beach being the core of the CD with the rest of far western OC in it was due to geography if nothing else.

My Santa Ana district has a higher Latino VAP with West Anaheim than the one you have with La Habra. It's better to put La Habra in the Yorba Linda district or the Norwalk district (mine has it in the Yorba Linda-centered district).

But what impact would such an arrangement have on my Asian Belt CD? It'd absorb heavily white Huntingdon Beach, surely that would harm an Asian candidate's chances of winning and make it plurality White...

Mine just absorbs small parts of Huntington Beach. It has over 30% Asian CVAP.

I get where you're coming from. I still stand by this as the ideal pairing of OC communities:



If you want to avoid that OC-SD split, I'd try and move Fullerton and Cerritos out of my CA-45/CA-46 districts and into LA-based districts and reconfigure from there.

[President Punxsutawney Phil]

How should the other Asian seat in LA county go? The one centered on Arcadia and Monterey Park.

[I’m not Stu]

My Asian Belt district takes in Huntington Beach to give white working class voters more influence as well, so rich whites don't have too much of an influence. It loses most of West Anaheim so Correa's district can have enough Hispanic VAP.

[Oryxslayer]

How should the other Asian seat in LA county go? The one centered on Arcadia and Monterey Park.

I just let that one be decided by what is best for it and it's neighbors. As long as you got all the cities with a good asian population in there it is fine. These cities don't have enough for one CD, so you can play around with what fills up the rest. For example, Pasadena and El Monte would work fine in the seat, but neighbors may desire them better so you go elsewhere. As long as the neighbors don't get too greedy and the seat ends up crossing the mountains like presently.

[I’m not Stu]

How should the other Asian seat in LA county go? The one centered on Arcadia and Monterey Park.

What do you want your LA Asian seat other than Judy Chu's (Arcadia/Monterey Park) to be? On my map, Chu's is plurality-Asian and the northern OC coast district is barely plurality-white with whites just barely outnumbering Asians.
