How Many of My AncestryDNA Matches Have an Ancestry Member Tree?

I posted How Many of my AncestryDNA Matches Have Attached Trees? back on 29 October 2018, so it has been 20 months and I thought I would update it. 

I used my top 500 matches in 2018, but I want to count the trees of all of my AncestryDNA matches with 20 cM shared DNA or more - so that is  1,500 matches.  This is a tick mark challenge, so I tried to be careful doing it.  

Here is the top of my AncestryDNA match list.  

As you can see, the list tells me if a match has a tree, and how many profiles are in their tree.  It also tells me if AncestryDNA has found a Common Ancestor and there is a ThruLine.

Here are my categories for the trees:

*  No Tree
*  Private Tree (linked or unlinked)
*  Unlinked Public Tree
*  1-10 Profiles in Public Tree
*  11-100 Profiles in Public Tree
*  101-1000 Profiles in Public Tree
*  1001-10,000 Profiles in Public Tree
*  10,001 or more in Public Tree

I also counted how many Common Ancestor matches there were in each category.

Here are my results:


Some observations about the data:

*  47.67% of my matches have a public Ancestry Member Tree.  (In 2018, that was 43.2%)

*  23.13% of my matches have no Ancestry Member Tree.  (In 2018, that was 24.4%)

*  7.33% of my matches have a Private Ancestry Member Tree. (In 2018, that was 8.0%)

*  21.86% of my matches have an Unlinked public Ancestry Member Tree (In 2018, that was 24.4%)

*  11.33% of my matches have a Tiny (1-10 profiles) Ancestry Member Tree (In 2018, that was 7.6%)

*  14.07% of my matches have a Small (11-100 profiles) Ancestry Member Tree (In 2018, that was 11.4%)

*  12.27% of my matches have a Medium (101-1,000 profiles) Ancestry Member Tree (In 2018, that was 13.0%)

*  8.00% of my matches have a Big (1,001-10,000 profiles) Ancestry Member Tree (In 2018, that was 8.6%)

*  2.00% of my matches have a Large (over 10,001 profiles) Ancestry Member Tree (In 2018, that was 2.6%)

*  0.47% of my Top 1,500 matches are labeled as having a Common Ancestor and a ThruLine.

*  The numbers above have not changed very much over the past two years, with some exceptions.

*  More of my DNA matches have a Public Ancestry Member Tree. 

*  More of the matches with a public Ancestry Member Tree have a tiny or small tree.

*  One significant difference is that there are 1,500 samples as opposed to 500 samples in 2018.

I have not done this type of tabulation for the other DNA match providers.  Stay tuned!
