The percentage of Welches on WikiTree which are considered as "Sourced" has remained in a narrow range between 94.4% and 94.7% since September. On the one hand, quite a number of the profiles with the {{Unsourced}} template on them are unlisted, which, in my mind, is a bit unfair, since privacy regulations make it very hard to source most people while they're still alive. (Unless they hit the news or something.) On the other hand, there are probably hundreds, or possibly even thousands, of unsourced Welch profiles on WikiTree which don't have any sources, but don't have the template, either, so even though I track those numbers, they're probably not to be trusted.
The percentage of Welches on Wikipedia (in other words, notable Welches) and on ThePeerage.com which are considered as "sourced" appear to have taken a dramatic jump this quarter. We have been able to add more sources, but most of the difference is that I've decided to count the sourced profiles as a percentage of the profiles on WikiTree, rather than as a percentage of the people listed on the source. (So, for example, 31 sourced profiles for people listed on ThePeerage.com out of the 34 profiles on WikiTree comes to 91.2% sourced, as opposed to 49.2%, which is what it would be if I were still taking the percentage from the 63 Welches listed on ThePeerage.com. I didn't make that change to make the numbers look better [although they do], but rather to give a more accurate picture of the state of the profiles on WikiTree. [The "Adding Profiles" chart already shows how much farther there is to go there, anyway.])
I've implemented a new measure this quarter, measuring the average sourcing level for Welches on WikiTree (or at least those four subsets of Welches which I'm tracking in my spreadsheet, and thus have sourcing levels for). Sourcing levels are as follows:
3 = 3 or more primary sources, possibly plus secondary sources
2 = 2 primary sources, possibly plus secondary sources
1 = 1 primary source, possibly plus secondary sources
0.5 = One or more secondary sources, no primary sources
0 = Unsourced or unavailable for analysis due to privacy settings
So the goal is to move the average sourcing level to 3, or at least closer to it.
