Happy Birthday, Giving What We Can!

Giv­ing What We Can re­cently cel­e­brated its 5th birth­day. It’s not much of a party if no-one ex­ter­nal con­grat­u­lates you, so here we go: Happy Birth­day, GWWC!

It’s pretty im­pres­sive how much GWWC has grown since those early days. Here’s a chart of to­tal mem­ber­ship, which I’ve put to­gether from GWWC emails and liberal use of the in­ter­net archive. I’m sure they have bet­ter data (with­out gaps!) in­ter­nally, but I’ve never seen this chart be­fore. Notably, growth seems to have picked up since the fall of 2013. Did GWWC change their strat­egy at that point? (or their mem­ber­ship-count­ing-method­ol­ogy?)

Lines going up are always good

Put­ting the same chart on a log scale, we can see that GWWC have ac­tu­ally done a rea­son­ably good job of sus­tain­ing ex­po­nen­tial growth.

Lines that go up on a log scale are even better!

Fit­ting a line of best fit to the chart, I es­ti­mate GWWC’s mem­ber­ship is grow­ing 73.1% a year. As­sum­ing 2% pop­u­la­tion growth, it will take just 30.25 years be­fore all the world’s pop­u­la­tion are GWWC mem­bers. Tak­ing over the world by the time I’m 58 sounds like pretty good go­ing!

Happy Birth­day, Giv­ing What We Can!
