The .info has always been larger because of the promotions from registrars. This causes a boom and bust growth cycle but it is a well recognised TLD. The .us ccTLD is around 1.6M domains so it is doing relatively well. With a bit of promotion and development it could easily be in the top ten. The .us is in the worst position of having .com as the de-facto US domain of choice.
The .ru ccTLD figure is surprising because it is rarely mentioned and it is such a large market. For the last few years the focus has been on the .de, .uk and .cn ccTLDs. The growth in .biz is steady but slow.
