Angel investors are quite often the wind beneath the wings of eager early-stage entrepreneurs. They are a hearty bunch who like to be close to the action and the buzz of a hot new idea, a blazing new startup, an inspired entrepreneur.

They also take risks that might make other kinds of investors blanch.

This is why a nicely package report about angel investor activity is important. (Angel investment trend data is not easy to come by.) Now us journalists have some angel investment data to cite when we do our stories, thanks to Silicon Valley Bank, the Angel Resource Institute, and CB Insights. I'm not gonna lie -- when you're on deadline all the time, it helps to have an infographic like this one handy.

* California accounted for nearly one-third of total dollars invested by angels; the Mid-Atlantic was 6.8 percent.

* Angel round sizes swelled to $700,000 last year, compared with $500,000 the year before. More money flowing to startups.
