As the year comes to a close,
we remember what was on our minds in 2015,
and the difference we made by coming together.
Take a look back at the most talked-about topics of the year.
The moments we shared in 2015 affected us all.
They shocked, moved and inspired us to take action.
They connected us.
Year in Review top 10 lists were measured by how frequently a topic was mentioned
in Facebook posts made between January and December 2015.
To put this list together, Facebook posts were analyzed in an aggregated, anonymized way,
and then ranked to create a snapshot of the year on Facebook.
