Yes, starting at 105,000 and on up to 300,000 (the max on the chart) the last zero seems to have been cut off,

I don't think it's just the histogram. Check out the Age vs Income plot. There's no way people aren't making over 100k.

I cut off the age vs income plot at 100k because otherwise it would severely compress the points where it would be really hard to discern anything from it. There are people who reported over 100K.

How about reporting in 1000's, instead of including every zero? Typical in financial statements.

I wanted to do that, but I'm not proficient enough in excel to do it quickly. Surprisingly enough, even getting the histograms was kind of a pain in the ass. I spent an hour and a half getting those 4 charts done.

Yeah, its always shocked me that Microsoft couldn't be bothered to put in decent histogram fucntionality where you can choose your buckets and it'll put together a histogram.

I didn't even notice, I guess it is some sort of bug (or "feature") with excel, because the data driving that chart is correct. The numbers are in the correct order (increasing in 5K increments), but the second half has a zero clipped for some reason.

Perhaps decreasing the font (I use Numbers so don't know whether it is possible in Excel) of the horiz. axis will allow the full text to appear (if you can't display in 1,000's).
