I'm confused how you get some of those numbers for the 1% though, it doesn't look like the chart is showing relative proportions like yours did (as in only the 1% colored section is theirs) it looks like straight numbers, so the 1% went from over ~62 Trillion in wealth down to over ~55 Trillion in wealth and back up to something over ~105 Trillion in wealth.
Umm, the $105 trillion is the total of all cohorts added together. Have another look at the data. You can turn off the other cohorts if you want to see just one cohort graphed.
I got the numbers by merely clicking on
the tab labeled "Table" to view the raw data from your link.
Over the same period it looks like the bottom 50% went from maybe 2 Trillion, down to less than 1 Trillion, and back up a bit over 2 Trillion?
The figures tell and interesting story, if you look back at the "bottom 50%" wealth, you'll notice there was almost zero growth for the 10 years
before the crash. 1997 Q2 wealth (bottom 50%) is 1.30 trillion (and that's not even the peak, but I'm using Q2's to be fair: if you pick a later date in 1997 or 1998 can actually show *negative* growth between 97/98 and 2007), while the very peak at 2007 Q2 was only 1.39 trillion (I missed this data point before, it's higher than 2007 Q3 for this cohort, so it's a fairer peak).
So in the 10 years between 1997 Q2 - 2007 Q2, the bottom 50% averaged 0.67% growth per year (one fifth of one percent). In the 12 years between 2007 Q2 (the peak before the crash) and 2019 Q2, they've averaged 3.1% per annum growth, a growth rate 4 times faster than the previous decade.
And this is measuring from the peak, not the bottom, so it accounts for both the crash and recovery. Growth since then is actually averaging much higher than 3.1%. Right now, the last 12 months growth for the bottom 50%'s wealth was apparently 12.8% per annum, and if you average growth rates since the absolute bottom for the poor (2011 Q2 - 2019 Q2), you get 36% per annum growth.
