I stand corrected - there was a 0.36% increase in 2014 once the merged branches are accounted for, pulling numbers from the thread below.
Yes, strictly speaking you are correct. But the increase in 2014 followed two years of far bigger drops in memorial attendance compared to 2011. That drop has now reversed but still represents much slower growth in memorial attendance numbers. As I said a few posts back, the best way to describe the US and territory patterns in recent years is "fluctuating" attendance patterns.
BTW, on what night of the week was the 2011 memorial held because that saw a huge increase in US attendance that was not surpassed until 2014.
