I don't live in
Israel either. I've just always considered
Aviva to be a fairly common Hebrew name and I remember seeing somewhere that it was quite popular in
Israel in the moment, but I don't have a chart unfortunately. I do remember hearing that
Noa was number one.
Here's one article I found about the name popularities, although they don't mention
Aviva. Maybe it's not topping charts at the moment like I thought.

I'm sorry if my comment came off a bit rude. I live in a predominently Jewish area although I'm not Jewish myself and I freqently meet people with Hebrew names. So it just seems odd to me when people are surprised to see these names in use.
America is home to a considerably large Jewish population. Maybe that's not the case where you live, but to me the thought that it would be "rediscovered" was just odd. Like worrying that the name
Catalina would be rediscovered when it's simply a very common Spanish name. But I do recognize that these names can become very popular among people who aren't apart of that culture.
