Share of Facebook users posting about the election. (Darla Cameron)

More than 1 in 10 U.S. Facebook users has engaged with the upcoming elections, according to exclusive data provided to The Post and visualized by graphics editor Darla Cameron.

Between July 10 and Oct. 19, 22 million U.S. users posted about the elections or liked a candidate page — roughly 11 percent of the site’s active users. Mainers were most active, while New Yorkers were the least active, as determined by dividing the number of unique users engaged in the election by the number of active users on Facebook in each state.

In Maine, where Gov. Paul LePage is engaged in an extremely tight reelection campaign, nearly one in five active users had engaged in the election over that roughly three-month period. Women ages 45 to 64 were the most active, while men  ages 18 to 24 were least active. In New York, just under 1 in 10 active users were engaged with the election.
