There is no way to tell just from that df output how much is in home as opposed to somewhere else.

Try this as root:

	du -shc /bin /boot /etc /home /lib /root /sbin /tmp /usr /var

That'll take a while to run, but it'll break it down for you much better.  The du command show disk usage.  The -s says "only show what I ask for, not a recursive mess", -h is "humanize (use K, M, G to show me sane numbers)", and -c is "Give me a total at the end." Sample output from one of my VMs:

root# du -shc /bin /boot /etc /home /lib /root /sbin /tmp /usr /var
4.9M	/bin
4.0K	/boot
21M	/etc
516M	/home
23M	/lib
24K	/root
4.6M	/sbin
28K	/tmp
457M	/usr
1.2G	/var
2.2G	total
