Phrase meaning of equal parts

IN THE CUT-THROAT realm of reality TV, “Wanted Down Under” is a survivor. A daytime fixture that has just finished its 13th season, the BBC documentary follows Britons contemplating relocating to Australia or New Zealand. Equal parts travel, property and life-makeover programme, it has a rival, “A New Life in Oz”, on Channel 5.

So the part from "equal" and onward gets unclear here since I can't think of a reasonable explanation to that equal part things. How often is "equal parts" used in such manner, how do I better make that out?

Solution 1:

The content of the programme consists of travel documentary, property (house hunting) and 'life-makeover' (advice on starting a new life) in about equal proportions.
