Democrats were twice as likely to make political donations last year compared with Republicans, according to data from the American National Election Studies (ANES).
The data by ANES, published in a Wednesday report from Pew Research Center, found 22 percent of Democrats and Democratic-leaning individuals reported making a donation in 2016, compared with 10 percent of Republican and right-leaning individuals.
Pew noted that the data marked the first election since at least 1992 during which Democrats reported making donations at a markedly higher rate than Republicans.
The data found that between 1992 and 2016, 15 percent of Republicans and 14 precent of Democrats reported donating to either a political party, specific candidate or outside group.
The ANES data also found that more Americans generally donate directly to political parties and individual candidates over outside groups such as political action committees.
From 1992 to 2016, the percentage of Americans who donated to an individual candidate grew from 6 percent to 12 percent. In the same time period, the number of people donating directly to political parties increased from 4 percent to 9 percent.
By comparison, the number of Americans donating to outside groups and PACs has stayed between 3 percent and 6 percent.
