There are different broods of periodical cicadas. Any given brood has adults emerging only once in 17 years and has a defined range of occurrence. It is a brood with a relatively small distribution, occurring mainly in eastern Ohio, the panhandle of West Virginia, and about a dozen counties in southwestern and western Pennsylvania. Adults will emerge in a couple of months mid-May, but with climate change issues this is becoming less predictable; when the subsurface soil reaches 64 degrees Fahrenheit, emergence will begin , females will lay eggs, nymphs will hatch weeks thereafter, and those nymphs will drop to the ground, burrow into the ground below deciduous trees, tap into the roots to syphon the plant juices, and remain underground for the next 17 years.
The adults of this brood will not be seen for 17 years, emerging again in Photo from Wikimedia Commons. Currently there are 12 broods of year cicadas, each with a different aggregate distribution. This means that in a year period, adults will be emerging somewhere in 12 different years.

It could also just be that cicadas are more carefully monitored now than they have been in the past. Scientists use crowdsourcing websites to help monitor broods.
