What is the put/call ratio?

Puts traded divided by calls traded. Above 1 means more puts than calls; it is read either as bearish positioning or, at extremes, as a contrarian sign that hedging is crowded. The open-interest version compares the standing book instead of the day's flow.

Why is SPY's ratio usually above 1 while single stocks sit below?

Index ETFs are the market's hedging vehicle, so puts dominate their volume; single stocks attract call speculation. Compare a ticker with its own history and with similar names, not with a universal threshold.

Where do the numbers come from?
