How does Ethnicity Conversion actually work?

[Culthrasa]

Hey all, question...

Does anyone know the nitty gritty of how Ethnicity conversion actually works? There are buildings which modify at "of current rate" but i can't find the base rate anywhere and what it depends upon... I have the feeling that culture output factors in somewhere, but does anyone know the actual formula?

The base is 4%. Then each 100 points of Culture of your own ethnicity is +0.2%. For example a region with 1000 Culture but 75% Celt and 25% Italic has 250 Italic culture only.
Then for each base unrest point of the population considered, lose 20% of this value. An Hellene population has 3 base unrest, so conversion will be time x80% x80% x80%.
Then up or down depending of national modifiers. Say if your value was 5% and you have a ruler giving +20%, then that's a relative percentage, so the end result is 5 x 1.2 = 6% (and not 5 +20 = 25%).

thz for the reply Pocus... let me see if i get it right...

I have a region with only Iranian pops (lets say 10 pops all unrest 8 ). I'm playing Judea and have a national modifier of -30% conversion.

I assume only one pop at a time is converting(or is the conversion checked every turn for every pop?). So one pop has a base chance of 4%*0.7(national modifier)=2,8% new base chance. It has unrest 8 so 2,8%*0,8*0,8*0,8*0,8*0,8*0,8*0,8*0,8=0,46% chance of converting. Since i don't have any own pops, culture has no impact. Is this right?

Also if i produce new culture through a building (monument etc), does that new culture count as Iranian culture or Judeac culture?

in this context culture is neutral, it merely increases the chance of a pop pt flipping.

also there are a few buildings that increase conversion and one decision (there is also a ruler trait but that is pretty random)

I think its one pt per region per turn (as a max)

Any chance of showing the cultural flip value somewhere in the UI?

Hi, I read the manual and I believe all the GUI on Culture. I have not seen where it says Culture impacts the Conversion. Is this a new thing?

Could someone provide me with an easier math example? Say a region is 50% my culture and 50% Hellenic.., what are the odds of converting if Region Culture is 0, if it is 100, if it is 500, and 1000. Thank you.

PS - I would think this is a very important concept and should be in BOLD somewhere.

[Pocus]

Yes that's probably something to show in the UI.

Note that the unrest we talk about is the base ethnicity unrest, not the one you see which get inflated for citizens if you have a lot of population. So in the case of the Semitic ethnicity, that's 5.

0.8^5 is 0.32

So 4% base, time 0.7 (if you have a -30% national modifier) time 0.32 will be rounded to 1. 1% per turn. One population at a time.

Now the Hellenic are at 2 and the Italic at 3.

Hi Pocus, great game. Not sure I understand what you are doing with math.., which is fine. Are you saying that Culture output does impact your nation's ethnic conversion? If so, could it be a significant impact if you focus heavily on culture? Thank you

This will help, definitively, but I would say it's better to build buildings boosting conversion rate (religious buildings)
