Dual Boot Install Question

I have Windows 7 and am going to reformat/reinstall, but want to try a dual boot configuration with Linux mint. If I install Windows creating 3 partitions: one for Windows, one for Linux, and one for all of my data (to be accessed by Windows and Linux), is there still any need for me to create an additional "home" partition during the Linux install? I am planning on creating a small swap partition.
