Some more interesting data. Not sure how it holds up against other alliances, but here it is:
10% of NPO nations (the 49 largest infra nations) own 638,090 of the alliance infrastructure (63.6%).
10% of NPO nations (the 49 largest tech nations) own 215,909 of the alliance tech (75.6%).
One more thing I noticed as I pulled this data. 81 Nations have been wearing NPO AA for 2 months or less; 110 nations at 100 days or less. Only one of these nations isn't a brand new nation/reroll or undeveloped nation.
