it goes to the failure of the survey probably, as it might fail to define what it means to be religious. i.e. there are many many "traditional" Israelis, who might do a form of friday night dinner every week, with kiddush (blessing over wine) and all. They might then go to a movie afterward. They keep kosher in a sense, but not in a strict manner. However, they might not consider themselves "religious" because they are using the term relative to "orthodox" or "ultra orthodox" people, and they don't consider themselves "religious" in that context. Heck, my across the hall neighbors who don't consider themselves religious, due it almost every week with their kids. Personally, my observation is that in the US, we would consider someone who takes part in religious ritual every week to have a significant form of religious attachment. It might also be that Israel has a large "secular" contigent. Some that consider themselves "jewish" but "agnostic/athiest", and some that don't consider themselves jewish at all. There's a large debate in Israel if this cohort is growing or shrinking. If one just looks at Tel Aviv, it seems huge, but Tel Aviv is a bubble, and there's a large amount of traditional people almost everywhere else. It just so happens that a very large portion of Israle's population is in the tel aviv area.
