It is as good a flooring choice for a 21st century family as it was for the pharaohs of Egypt. Ceramic tile is appropriate anywhere in the house; indoors or out; below, on, or above grade level.

It's important to choose a tile that is appropriate for the rooms in your home. To help you understand the various options, the Porcelain Enamel Institute [PEI] developed wear ratings (groups) for ceramic tile's suitability in various spaces:
