Two years later, I'd say it's close to 100%.
It is not very common for any job industry to have close to a 100% employment rate. I just have a hard time believing it is that good in a highly saturated field in the midst of a huge recession. Wow, I'd say that is pretty impressive if it is actually true....but what kind of employment is it? If a lot of those are unpaid internships, then no, I don't consider that real employment - no matter how great someone thinks their chances are of someday being hired permanent. Employment = paycheck. Unpaid internships are a huge problem today, not just in law, but in other careers.
It's an estimate based on anecdotal evidence, I don't know what the specific number is. But two years after graduation, yeah, the vast majority of my classmates are employed as attorneys.
That doesn't mean that they're all making great money or working at swanky firms, but they are employed as attorneys (not LL.M students or unpaid interns).
Remember, I'm talking about two years after graduation. It took some people a long time to find a job, and for many they're certainly not working at their dream job. Some have great job that they love, some are slogging through insurance defense. Others tried to get hired at firms, had no luck, and hung out their own shingle.
One thing that is different about law from many of the other fields mentioned is that you can always open your own office and start taking cases. Will it be hard to find clients? Yes. Will there be a learning curve? Yes. Will you make big money immediately? No. But it can be done, and you get better with time. If you know how to hustle and are willing to work hard, you can build up a nice practice.
