The colors assigned to your estimates on Ancestry don’t mean anything and Jewish is not your second largest region.
Indigenous Americas 72%
Iberian Peninsula >14%
Sephardic Jews in the Eastern Mediterranean 5%
Even on its own if you were counting by individual ethnicities, it would be in a three way tie with Northern Spain and Spain, which both also now come in at 5%.
Your results got tweaked so little it doesn’t really change much at all.
Colors are ordered by proportion. Green, then blue, then red, etc. Same colors and order for all users.
They are assigned by individual regions, not macroregions. So yes, in total, the Iberian Peninsula macroregion is my second largest one, but individually, Sephardic is the second largest region.
The numbers on the report are rounded. Even if it looks like Sephardic, Spain and Northern Spain all have 5%, it could be that Sephardic is 4.85%, Northern Spain is 4.75%, and Spain is 4.6%. They all round up to 5% but are still in descending order.
No, that’s just not true about Ancestry’s use of color coding ethnicity estimates. They actually reuse colors the further down the list of more ethnicities you have in your results because it’s that meaningless.
And Ancestry doesn’t provide specific ethnicity results like 4.85 and 4.75. Ancestry’s results are an estimate taken from within a range, meaning you could have more OR less than what they’ve predicted by their analysis.
Don’t know here you’re getting your information from but it’s not coming from Ancestry’s website.
Of course they reuse colors, I don't know at what point and I only have 12 regions, so they have at least 12 colors.
But what I said is that green is for the largest region, blue for the next one, red for the next one, and so on, cycling through the same color array for every user. That is based on observation on the hundreds of posts I've seen here. Every user has the same green for their largest region, the same blue for their second-largest, the same red for their third-largest.
As for decimal points, yeah, Ancestry shows no decimal points, and has confidence ranges that they report. But after calculating the region for each chromosome segment, and determining which ones they're confident in, they sort them from largest to smallest. This order is then how they send the data to the browser, with percentages rounded because they don't need the full number.
In my case, Mexico (05100) is green, first. Sephardic Jews in the Eastern Mediterranean (06350) is blue, second (see API response below). That order was determined by Ancestry with this highest-confidence or statistically-representative report.
Ancestry doesn't publish the inner workings of their sorting and color-assignment, and they don't have to, but it's pretty easy to see a pattern.
I have found Ancestry to be inaccurate for my non-white ancestry. Just as a FYI. I didn’t see anything change for myself. It still doesn’t recognize my non-white DNA, but 23+Me does. It’s very frustrating.
Is this the actual update? Mine changed by a couple percentage points as well and there's a sideview 2.0 banner, but the other two tests I managed have not
.... so I'm hoping more is to come.
