Social Weather Stations data

I was looking over this article for copyediting purposes, and it looks like the math doesn't quite add up on the social weather stations data for totals vs percentages, especially when looking at the percentage of a smaller group.

For example, 36% of all households bike; this amount is listed as 10 million households. If 24% of those households own their own bikes, that would be 2.4 million households, not 6.6 million.

It seems that the way the data is presented in the source article makes this same error, but it doesn't fit with statistical understandings of how a percent of a percent works. The percents within these categories generally add up to less than one hundred -- in this example, the percentages that own vs. borrow bikes added up to 36% only. That implies to me that 24% of all households are bicycle using households who own at least one bicycle. Not that 24% of the 36% do. If 6.6 million actually own a bicycle, that would be 66% of bicycle-using households.

I'm not sure what we can do about it, but it seems to be a statistical reporting error throughout the tables & data both here and in the source. Ideally we could find the raw data of the source and estimate actual percentages from there.
