Also, I'm fairly certain your calc's for EPR, ARE, AMB and SLG are wrong, as their div's haven't grown by those percentages. All four came public in 1997, so I'm guessing you used their partial div's for the year for your base to calc div growth. AIV is also wrong; I don't know where your numbers are coming from. But hey, I tentatively think that the remaining five might be right! Just follow this simple rule: GGP should always come out #1 in historical dividend growth among REITs. If you get another result, your looking at the wrong info.
This article needs a bit more homework. GTY and RYN weren't REITs for the entirety of your timeframe, so their dividend growth is skewed upward by their REIT conversion. PEI's div growth doesn't reflect the fact that the company foundered through most of the 90's and had to cut its dividend and restructure through a backdoor UPREIT (in 1997) before starting to grow again. PSA's div growth is skewed by some of its formation transactions.
