The Top Birth and Death Widget located on Family Dashboard will show you the Top 10 countries that have the most births and most deaths in your family tree.
Once you see the widget on your dashboard (as shown on the left) click "View larger map."
This will bring up a separate window that will have a large map with pink and yellow tags over various countries on the map.
The yellow tags have a picture of a rattle on them and this symbolizes the birth countries. They will have a number 1-10 on them, which indicates where it falls in the Top 10 counties.
The pink tags have a picture of a headstone on them which symbolizes the death countries. Like the birth countries these have numbers that rate them in the Top 10 countries.
The numbers at the bottom of the page correspond with the tags and list the Top 10 birth and death countries for your ancestors.
When you click on the county it will give you a list of all the people that were born/died there, the date, and the exact location.
