Note: Three data points were removed from the sample due to my subjective opinion that they were fake. Any self-reported IQs of 0 were removed. Any self-reported income of 0 was removed. 

*89% of the LW population is between the age of 15 and 34.

**88% of the LW population has an IQ between 125 and 155, with an average IQ of 138. 

****Median numbers were adjusted down by a factor of 1.15 to account for the fact that the source data was calculating household median income rather than individual median income.

Update 1: Updated chart 1&2 to account for the fact that the source data was calculating household median income rather than individual income.

Update 2: Reverted Chart 1 back to original because I realized that the purpose was to compare LWers to those in similar income brackets. So in that situation, whether it's a household or an individual is not as relevant. It does penalize households to an extent because they have less money available to donate to charity because they're splitting their money three ways. 

Update 3: Updated all charts to include data that is filtered for US only.
