Trouble Finding Recent Figures for Net Migration

[Sam Gaddis]

I often see people on BP recommending that market analysis should always involve reviewing Net Migration – however, I've been unable to find any good sources of data that look at net migration in recent years.

Most sites (like City-Data) use the US census data measuring net migration from 2000 - 2010. And of course I'll look at that, but how much should you trust data that's so old? 

I wouldn't bother with it except that I'm always hearing shocking figures about population growth in local news sources (Austin is growing by xx people per month), so I presume someone has more recent figures on this somewhere. 

Any ideas?
