If I had children near the age of college, I'd steer them towards studying "statistical sociology". I am not even sure that there is such a field yet, MIT doesn't seem to have it, but I would bet that this will be a big research area in the very near future (The search on Google yields 1250 results today, I wonder what it will in a year).
We live in the golden age of statistics. Data is being collected about you in more ways than every before. Computers are ubiquitous, that's why. On the web, every click you make is indexed, tagged, measured and calculated. There is a lot of data collected, and with data comes statistics. If Google can make a Chinese to Arabic translator without anybody speaking either language, that means with enough data, language translation looks like a statistics (math) problem. That is the golden age of statistics. One of my favorite posts, is all about this and how statistics can even expand our understanding of history.
Sociology is entering its golden age with the help of statistics. In social networks, one's popularity can now be quantified, it's actions measured, and social effectiveness determined. Not just popularity, but all social actions of a person, including how many blog posts, comments, chats, winks, links they create are all calculated. From these, an equation of "social effectiveness" will emerge. We are seeing signs already. There is a great company in San Francisco named Red Bricks Media, that's doing a great job in understanding the impact of sociology in our age. They help companies identify influencers, and create buzz marketing. "Buzz marketing", while I hate the term, is the first application of statistical sociology. There will be more and more on the horizon. Just wait till ecommerce becomes social.
So if you have kids in high school, and they are mathematically oriented, channel them to take probability.
As for my kids, I first have to teach them what a "variable" is, and then find a creative way to generalize the concept and teach them what a "random variable" is. That may take some time :-)
