Questions regarding the bar charts:
The last FHAR for 2021 reported statistics for 2019, 2020, and 2021. These numbers were 67.6%, 68.3%, and 69% for the 4 Generations block. The first FHAR report for 2022 shows the following numbers for 2020, 2021, and 2022: 67.8%, 68.2%, and 39.2%. I do not understand the differences for the same year bars and how the 2022 percent can be 30% lower. This trend appears across the Member Login and Family History Activities blocks. I can understand a small difference due to members moving in and out, but 30% is baffling.
Can anyone help me to better understand the year-end transition of the numbers?
