Numbers and links are pulled directly from i18n and entered manually by Andy monthly here.
Its a good idea to read the i18n section in the documentation section to understand how this process works as you’ll be creating a modal window for any stats which are made up of more than one dataset combined on the homepage and pulling the numbers in directly from i18n.
All the stats and their links can be found here: Stats and Links
Please turn the stat title for each bottom level stat into a link, which is also accomplished inside i18n.
