As-salaamu alaykum, Christine,
Interesting, I had assumed every Muslim I knew made their prayers (on time). Maybe because I've seen that my family all prays on time, alhamdulillah (and funny, my parents try to beat each other in praying "more on time" than the other).
By "missing," I would think you mean voluntarily missing the prayer time, and then not making it up, right?
Alhamdulillah, I haven't voluntarily missed prayers since the time I decided to pray regularly on my own (which was somewhere in my youth...). Now, the quality of the prayer, that's a different story (and one I constantly ask myself about).
If I happen to sleep past Fajr time (rare, but it does happen), I make it up when I get up. And hope to not miss it again! I'm always reminded of Hamza Yusuf's quote, which was something like: If you don't get up for Fajr, don't get up at all!
May Allah make us all steadfast (and remember that Shaytaan gives us plenty of excuses to use),
