I don't want to take away from the good things that Seattle has done with transit, but it's worth pointing out that Seattle is far and away the fastest growing city in the US, with an astonishing 3.1% (21,000 people) between 2015-2016.
If ridership increased by 4.1% between 2015-2016, then population growth alone may account for a significant chunk of that.
