# What is the meaning of pct_trend_adjusted in FiveThirtyEight's polling data?

I'm working on polling data from fivethirtyeight. What is the meaning of the pct_trend_adjusted column here? I understand that pct stands for percentage, but I don't get what the trend is that they are adjusting for, and how these figures are obtained.
