I really wish they provided an expense break down for these numbers and knew some specifics of the families quoted - do they have cable, do they run the AC at 72 degrees... do they drive a Canyonero http://www.youtube.com/watch?v=e4QgWRycd7I?
It may not provide all the details you want, but you can find the full report here:
http://www.cnpp.usda.gov/Publications/CRC/crc2011.pdfThinking about big expenses associated with our LO in the first 5 years of his life they include ...
~$2K being born
~$20K my lost income year 1 (cut back to 30 hours/week from 40)
~$10K my lost income year 2 (35 hours)
~$6K childcare (part-time) years 0-4 ($30K total)
~$8K preschool (part-time) year 5
~$1.2K per year health insurance (adding him to my employer-subsidized policy) (~$7K total)
So that's ... what? $79K for the first 5 years (really 6, counting the year before his first birthday). I'd guess our costs will go down as we move from paid childcare/preschool to public school, but I expect them to go back up again as he gets older and acquires more expensive hobbies (than he has now). I'm OK with that.
Our housing's remained constant (though we live in the house DH bought to move his now adult kids to when they were in elementary school; in another scenario, that might have increased). Clothing, "stuff," and activities have been pretty incidental. I did upgrade to a different car after he was born (I didn't want to drive him around in my 1994 pickup truck), but those costs have been fairly incidental, too (I'd likely have upgraded/replaced around then anyway).
Our travel expenses have gone up also, as I've opted to fly (essential, there's an ocean in the way) to visit extended family, something I might well not have done (and didn't do as much of) absent the kid ... and of course, we now have to buy an additional ticket. But that's probably not typical and certainly not (absolutely) essential.
